The future prospects of NiMH batteries

Category: Uncategorizedadmin @ 1:26 am

In hybrid vehicles, nickel metal hydride batteries in the next five years to maintain an advantage and will dominate a larger market share. The lithium-ion batteries used in hybrid cars will gradually raise the share.

 

Institute of Physics, Chinese Academy of Sciences researcher Huang claims that B133EW01China’s nickel-hydrogen battery technology is not mature industry; there is no mass production capacity. If you now go to the introduction of advanced equipment, so the time has late, too big a price to pay, how to develop the need for a comprehensive thought.

 

But at the same time, China is rich in nickel metal hydride battery raw materials. China Automobile Industry Association, Executive Vice President and Director General Yang said: “Our country is rich in rare earth materials, but our technology can not be processed rare earth materials for automobiles would use the permanent magnet materials, we can only export of rare earth, permanent import Magnetic Materials.”Therefore, how to maximize resources for many of the industry thought.

 

Huang Xenia suggested domestic enterprises NiMH batteries should further enhance the level of key materials, for integration into the industrial chain. “If a large number of rare earth resources into car battery materials, China is still a good chance. Master Keli Yuan NiMH battery raw materials, the company is the largest manufacturer of nickel LP141WX1 foam, nickel metal hydride battery if domestic companies are like the company into the same chain, although not achieve the main role, but can play a key role in material supply, as valuable. “

 

Beijing Nonferrous Metal Research Institute, Senior Engineer Energy Materials and Technology Research Institute, Dr Wei Navy to reporters about the nickel-hydrogen battery, a new application areas - replacement batteries, he thinks this will be the future of nickel-hydrogen batteries as a major development direction. “Ni-MH battery applications in emerging areas such as replacing disposable batteries obvious advantages, has shown very strong growth momentum.” According to him, Japan’s Sanyo products for the consumer market has developed a low self-discharge rate of Ni-MH battery , after 1 year storage capacity retention rate of 85% capacity retention rate after two years 75%, completely breaking the traditional nickel metal hydride battery storage performance difference (ie self-discharge rate and storage capacity retention after 1 year was 50% Two years later, the basic capacity to zero) the disadvantages of the traditional Ni-MH battery into the era of new applications, is expected to replace disposable batteries. A low self-discharge rate of NiMH battery is equivalent to a one-time 1000-2000 Day, and the larger, higher power, fully green, dry batteries can significantly reduce the one-time application, energy conservation, protecting the environment.

 

It is understood that, in 2007 and 2008, low self-discharge rate of Sanyo Ni-MH battery shipments were 25 million and 30 million, and increased year by year. As at the end of October 2009, the company’s low LTN141W1 self-discharge rate of Ni-MH battery shipments has accumulated more than 100 million. Wei told reporters that the Navy, some domestic universities, research institutes have also been doing research in this area, but not excellent, lots of low self-discharge rate of the stability of a good NiMH battery anode material, domestic battery and low self-discharge Battery compared with foreign products, there is a wide gap.

How much do you know about laptop battery?

Category: Uncategorizedadmin @ 11:02 pm

With the notebook performance and technology continues to improve and improve laptop battery from nickel-chromium batteries, nickel metal hydride batteries to lithium batteries and even the development of future fuel cells may be popular, let me go with you to understand about laptop batteries.

 

From the notebook was born that day, the battery of this “servant” on its side have been with no battery, it can be said can not be called the laptop “mobile computer.” With the notebook ProBook 6440b performance and techniques have grown rapidly and improvement, it is “servant” of the “quality” has become increasingly high nickel-chromium batteries from the past, NiMH battery until now, has the use of lithium batteries and even may later Puji’s Ranliao battery, few people care about this and closely related to what laptop - the battery, then let me go with you to understand about laptop batteries.

 

Cell classification and distinction, and we typically use the battery has three kinds, Nickel-chromium batteries, Ni-MH battery, and Lithium battery; they are generally expressed as: Nickel cadmium NI-CD, Ni-MH, Lithium Battery LI, in recent years, the field also appear in the notebook of a fuel cell, its only by-product water and heat, no noise, the basic pollution-free, efficient power system than the normal high of more, to 43 ~ 58%, if the reaction heat is also used, the efficiency can be up to 80%! It is a clean environmentally friendly power. Because of its technology is not perfect, there are still many problems to be solved, and now its cost, size, weight, and fuel, both for convenience and absolutely no lithium batteries and polymer lithium traditional competition.

 

Nickel-cadmium battery NI-CD, since it was too early, so has many shortcomings of headache, such as: bulky, heavy weight, small capacity, short life, there is memory effect, etc. (nothing), is no longer used. Now mainly NI-MH batteries are Ni-MH and LI lithium two. Ni-MH battery which is also active in the battery industry, time, compared to other batteries,Samsung IA-BP85ST Battery nickel metal hydride batteries to a number of more environmentally friendly, it is also by far the most environmentally friendly battery, while the lithium Well, is small, light weight, large capacity, low memory effect, charging time and short, well received by users like, but you will often see the back of the battery and dispose of lithium batteries handling instructions? Because discard the lithium batteries will cause environmental pollution.

 

Now, some people may have misunderstandings on the lithium batteries, lithium batteries do not remember that, in fact, lithium is not no memory, but memory is relatively small it looks not very clear. Lithium long time ago there, and it is not safe when used often in charge when burning, burst, and this may be because the lithium element too active reason. Then there is the improved lithium-ion batteries, lithium element added to inhibit the active ingredients, so that lithium truly achieve a safe, efficient, convenient, and also followed the old lithium eliminated. As to how to distinguish those from the battery of the label can identify lithium as LI, lithium-ion battery LI-ION. Lithium and NiMH rechargeable batteries another difference is that the number of charge cycles for the lithium HP Pavilion dm3 Battery generally only 400-600 times, specially modified products, but 800 times, usually with 2 years on the legs, which is why the general notebook battery manufacturers to take only 1 year for repair reasons. In contrast to the lithium battery, nickel-metal hydride rechargeable battery would much more, usually 700 or more, good quality battery can charge and discharge 1200, Ni-MH battery life than lithium batteries often had.

 

That said, battery materials, we look at the battery in the place of origin, the origin of the general cell batteries in Japan, Korea, China and Taiwan Province, in particular, mostly in Japan. The more famous of Japan’s Sanyo (Sanyo), South Korea’s LG, Samsung, etc., I use IBM laptop batteries that Japan’s Sanyo (Sanyo) Company production.

 

Cells formed by the batteries, the general has been said 4Cell, 6Cell refers to the number of batteries within the battery, such batteries are readily available in the market, prices are generally 10-20 per month, South Korea, China and Taiwan mostly based processing and production of batteries are the core of Japan. In the next-generation battery batteries, some have no form of this park but used batteries is a lithium polymer block, used in some capacity in order to get more and more small size.

 

As the original battery is now available in the market with very high price about 1000-1500, so some friends started to adopt its own battery replacement batteries to achieve the purpose of extending battery life. Theory should, it is possible, but due to technology reasons, the battery generally are using ultrasonic welding, there is no gap, difficult to open, were separated from the very difficult even close, I see on the electronic Shangwang to the two hands are their own battery replacement batteries and then sell finished, the battery junction can see that there are clear signs after 502 glue, even with the batteries, replace more time to find a match difficult. And some laptop batteries such as IBM, there is a protection circuit inside the battery, the event of failures of the internal temperature is NB-2LH Charger too high, it will automatically cut off, has a protective effect, if the replacement of batteries, when accidentally the disastrous consequences of this piece of circuit is damaged . So I still is not recommended to replace batteries, if need to replace the professional and technical staff are also looking to help change.

The Construction of Laptop Batteries

Category: Uncategorizedadmin @ 1:35 am

1, laptop batteries Category:

Media can be divided in accordance with nickel-cadmium battery NI-CD, Ni-MH, lithium LI, Li-ion and the latest lithium-ion polymer battery, most laptops now use lithium ion batteries.

 

2, the structure and capacity laptop battery calculation:

No matter what kind of laptop batteries, are protected by the batteries + charging circuit, the charging protection circuit in turn, the control chip to prevent over-charging the battery overheating and prevent overheating protector formed. General notebook batteries are 10.8v, 11.1v or 14.4v’s. How was the number ProBook 4311s of batteries inside it?

Remember, each section of lithium-ion battery voltage is 3.6v to 3.7v, so to get all three voltage, you first need three or four batteries in series, and then by the n group composed of such batteries in series battery . For example, your battery nominal 10.8v/3600ma, it may be 6 or 9-core, single core power-saving capacity of 1800ma or 1200ma

  

3, lithium-ion battery charge and discharge limits:

Why laptop battery protection circuit to be built-in charging? This is because the lithium-ion battery has a charge voltage limit, the general 3.6v battery charges no more than 4.2v, and otherwise it may explode. This requires an external device monitoring charging voltage, in approaching the critical value of the time to stop charging the same, batteries have discharge restrictions, 3.6v battery can not discharge more than 2.75v, otherwise it will lead to battery failure, which is what we often that the “over discharge.”

   

4, lithium-ion batteries Model:

Lithium-ion battery signal is provided in accordance with its exterior size, the general notebook batteries used with the following models: 18650,18500,17670,17650, 103448,103450, to 18650, for example, the power core diameter 18mm, length 65mm Therefore, a 18650.103448 and 103,450 are battery box, IBM 240 series on the use of this type of battery, high HP Envy 13 Battery width to length was 10mm, 34mm, 48mm. Laptop batteries are generally used 18650 or 17670 batteries, mainly because the two batteries have larger capacity, smaller size, are likely to cause the shape of the battery needed.

  

5 What are the change batteries?

Change batteries in the battery pack is the original batteries out, replace the other batteries. Batteries for battery manufacturers are strictly prohibited conduct, because it has a very high risk. When changing batteries in the battery itself with a voltage soldering iron or other tools to easily generate electrostatic discharges cause a short circuit, causing combustion explosion. On the other hand, due to charging protection circuit has been written into the original batteries information (capacity, discharge curve, etc.), changing batteries is likely to lead to circuit failure protection, which can not be charged, or even lead to over charge explosion. So for batteries are dangerous, and there is a risk, it must pay attention! !

  

 6, change batteries need to pay attention to?

Risk for batteries, but to save money, so we have to take the risk. Change batteries before the battery should shine some attention (usually around 5% can be placed). This is because the new batteries with only a little more than their own power, if you put a fully charged battery Naqu for batteries, charging protection circuit will always remember with your battery is dell Vostro 1220n battery full charge, even if no electricity for the new batteries circuit is also not allowed to recharge, and many of the core after changing the battery can not charge for that reason.

In addition, the change should carefully check the batteries before the batteries type, capacity, brand, sometimes different brands of batteries into the charging circuit, the circuit will automatically lock (small technology developed in Japan), resulting in failure for the core. So as far as possible the same kind of want to change brands of batteries.

Also, for all batteries must be replaced, must not only change some batteries, it is very dangerous, they must face significant loss petty advantages.

Also, do not blindly pursue high-capacity batteries, because some of the circuit for the detection of the new capacity is greater than the original batteries when the batteries will be locked, or only allow charge to the original capacity, so high-capacity batteries for success rate is very low.

  

7, after changing batteries need to pay attention to?

After changing batteries should note that the first three full charge and discharge must be filled up, the full charge after a period of time, and then start using; discharge to put 5% and then start charging. This is because the new batteries and the circuit between the original required some adjustments, to achieve accurate measurement of the degree of power. Some of the new-for-cell battery used to power down immediately when 30% to 0, this is actually quite normal, indicating the circuit is not yet complete self-calibration (calibration), measurement is not accurate. Usually after two or three times to achieve the best possible state).

  

8, who changed the battery batteries can and back to the core?

A battery changed his batteries once again for general or core, as long as the circuit is no problem. But after several circuit core solder for intensive, not easily again on the tin, and possible weld, Weld’s case, it is generally do not change the core of another.

  

9, change batteries will bring things:

Notebook computers are certain to bring, and the other to bring battery monitor or battery mark like the software, for full charge capacity immediately after testing, and charge-discharge curve. General business will give you some time warranty, so about 15% of charge as long as the spot to test on the line, get it back again to the devil test.

Exacerbation of Hotspot Effect for Battery Industry

Category: Uncategorizedadmin @ 2:04 am

Held in May this year, the second round of Sino-US Strategic and Economic Dialogue, the U.S. Secretary of Commerce, Locke said he United States will in the new energy technologies and employ Tonguing areas of cooperation, including new energy automotive industry is one of cooperation in such key directions. From the perspective of today’s news reports, yesterday met with Premier Wen Jiabao attend the third China-Japan high-level economic dialogue Katsuya Okada, the ProBook 4710s Japanese Foreign Minister and his party, said that China’s imports from Japan and the Japanese fast investment growth, circular economy, green Economic, environmental protection cooperation is expected to become a new bright spot. China and the two most important economies in the world are focused on the development of green this year, economic cooperation, apparently to speed up industrial restructuring, changing economic growth pattern, to achieve capital growth and restructuring objectives.

 

Based on past experience, the Government has received major support from the industry are often extraordinary development. Hot look from this year’s market, though stocks were twists and turns, but the low-carbon economy is a new energy battery plates, particularly the performance of a very eye-catching plate. Because the development of new energy vehicles in China in the electric vehicle industry in particular has a resource advantage, the key parts electric car motors and batteries as the key needs of rare metals lithium, manganese, rare earth, China’s large reserves of these resources, and production in the world occupy more large proportion. Technical level is not enough in the past restricted the development of relevant industries, as China’s strengthening and leading the dell-inspiron-1570n-battery-p-98572.html”>Inspiron 1570n United States and Japan cooperation in science and technology, related field may be a breakthrough. This year, many places have been introduced in the support policies of new energy vehicles, huge subsidies is bound to stimulate new energy vehicles, the rapid development of the whole industrial chain.

 

From the hot market for new energy vehicles to explore effects of view, is the vehicle manufacturers initially, followed by transition to a key component of new energy battery, then began to tap new energy battery lithium primary lithium upstream resources and electrolyte, such as Jiang special motor The rose and the development of lithium-earth Yichun Mine was not unrelated to the recent hot spots continue to fuel-cell proliferation effect, Tongji Science and Technology is therefore of three consecutive daily limit. In addition, new energy battery of other raw materials have also sought after by the market, such as involved in lithium-ion battery cathode material lithium iron phosphate Hengdian DMEGC development also rose 40% last week. Hengdian East magnetic technology is also the upstream manufacturers Jinrui daily limit today in one fell swoop. In international cooperation, policy support and investors favored the background, is expected to focus new energy battery industry will continue to in-depth interpretation of effects. The relevant EN-EL3 section of stagflation attracts varieties investors due attention. Such as low-cost fuel cell unit 000 571 new continents A, the same investment in the production of lithium-ion battery cathode material lithium iron phosphate, etc. 600 078 Chengxing shares.

 

From Monday the broader market trend, the U.S. stock market in the U.S. Federal Reserve Chairman Ben Bernanke expressed his support to maintain a loose monetary policy to stimulate the rebound department, under its impetus, for two consecutive days in 2600 were supported above the opening A-share rally heavy volume , units fully active. Institutions Shigekura consumer stocks, pharmaceutical stocks, and favored by hot money and a new lithium battery materials, the average mine stocks rose more than 4%, indicating that both optimistic and institutions and the hot money, but banks, real estate has not been represented much as a heavyweight restricted the space for broader market rally. Thus, while the broader market rebounded Monday, but if the heavyweight has been anything, the continuity may not be too strong rebound; broader market will remain cabinet vibration pattern.

The Trend of Battery Industry’s Market to be Optimistic

Category: Uncategorizedadmin @ 1:20 am

Hengdian DMEGC is a well known company in October 2009 construction of 100MW 262 million investments in crystalline silicon solar cell production line in March this year, 316 million construction ProBook 6545b investment in 100MW solar silicon film project.

 

100MW solar cell current project has been put into operation the first two lines, and sales income 88 million Yuan, total profit of over 10 million Yuan. The substantial expansion of production capacity once again, reflects the company’s solar business expansion. Full production will reach an annual output of 300MW solar cells (including the 200MW and 100MW monocrystalline silicon solar cell battery slice) and the production capacity of 50MW cell components, annual sales revenue of 3.1 billion Yuan, total profit of 304 million Yuan.

 

Article V has entered the construction phase of solar wafers, corresponding to the total production capacity has reached 125MW. Solar energy business revenues this year, the company could substantially VW-VBG260 exceed expectations. Of course, the latest general meeting of shareholders is a lot of people excited, they will be the talk, the talk is not to release the information or does that should be held responsible, spread of public information is also fast and Mian is also widely.

 

This is how I know the business from a friend in private circumstances and the information from the public for some time that the development of enterprise information. But to know the basic principles of the stock up or pile up by funds, and various public and non public statement just to play a role, that is raising the expectations of share holders, 18 per 25 hours into the expectations Yuan, 25 Yuan, but when the stock price expectations has become 30. Now of course, from time to time will be daily limit, only shows that there is continued access to capital.

 

The hands of people who have huge amounts of money found more and more difficult to DMW-BCG10 study them is also increasing. Behind the stock of cattle or more money ah! That is more money, so the battery will be mad up.

 

The current stock market trend for the term: the new energy, continue to develop up period. Perhaps the trend of the future will be higher! All good investments, all of the battery industry’s future, have very high expectations!

Methods to Identify Cell Phone Batteries

Category: Uncategorizedadmin @ 1:49 am

The basic method to identify the majority of the brand is that the face of new batch of batteries manufactured in the identification of the means be different.

 

1. Nokia Battery

Method 1: Battery positive real rough with your fingers without a sense of touch, but leave the battery with a fingernail scratch was evidently feel more sand; real battery terminals with the plastic shell out easily VGP-BPS21 battery with a fingernail marks, and fake batteries are very hard.

Method 2: I’m up and down the battery cover, tight joints, and leave the battery joint space is relatively too large, especially in particularly evident in the four corners.

 

2. Motorola Battery

Method 1: fake cell worse printing quality a lot, the edge of rough characters, bar codes also often have broken the case, the battery really close contact between the electrode and the shell, and four electrodes are in the same plane, very neat.

Method 2: Now the batteries are the batteries were sold with a red mark: “random batteries, such as retail, manufacturers can not enjoy the three guarantees”, used to prevent businesses with random false battery replacement battery.

 

3. Sony Ericsson batteries

Method 1: the battery is really superior engineering plastic with texture, but this is only the difference between previous approaches. Now the fake batteries have also been matte treatment, but leave the battery cover, matt VW-VBG6 to coarse particles is much dimmer, and leaves the battery weighs less than a really thin battery.

Method 2: Look electrode, in the lit area, real battery electrode has a one small box Obscure, but leaves the battery electrode without any treatment.

Method 3: general illustrations, most children in the lower left corner of the painting marked a clear illustration of the original electronic printing, you can vividly see the children’s eyes and mouth have fingers, but the false call is basically a few black specks, not your fingers no.

Method 4: geographical indications, the original electrical origin marking is very clear, leave the location of the battery a lot of writing is distorted, and contour lines of the letter is not clear.

Method 5: In the back of the battery at the top of the right contacts for the three copper, said his side has a relative thickness of approximately 0.1MM 5MMX3MM the protruding part of the site fully integrated with the shell of the polymer.

 

4. Samsung Battery

Method 1: I’m a matte plastic battery handle, but  HP Pavilion dv3 Battery smooth feel, although there is a fake battery matte treatment, but feel jerky.

Method 2: Tag: true character of the edge of the battery is very smooth, red, bright-colored printed notes, fake batteries character edge rough, red is relatively bleak, and the characters are off the word situation.

Method 3: bar code: bar code true battery has Ao Tugan, but did not leave the battery.

Power Norit to Develop Solar Thermal Market

Category: Uncategorizedadmin @ 10:09 pm

According to China’s “long term renewable energy development plan”, China’s annual amount of solar energy resources can be developed up to 1.7 trillion tons of standard coal equivalent, which includes wind, hydro, biomass, geothermal energy, including renewable energy equivalent to all other standards Less than 6 billion tons of coal. Accordingly, experts VGP-BPS15 battery predict that solar energy will gradually become the dominant global energy. Solar energy development at this stage include solar thermal and photovoltaic camps, from a realistic combination of factors to consider, slightly obvious advantages of solar thermal, solar thermal technology at the same time as the rapid improvement and force the rapid growth of companies such as Norit, solar thermal and photovoltaic power generation will also be the advantage of salon competition.

 

At present, photovoltaic field all to grasp core technology in the developed countries. In which European governments to preferential policies to support enterprises to develop solar photovoltaic industry, are also ways to use subsidies to encourage people to use solar energy. “But as we all know the reasons, European countries do not produce polysilicon in their own countries, but rather the production of polysilicon into the developing countries,” Han Tianen said, “Polysilicon production is an energy-consuming process, to produce carbon dioxide, which a carbon emissions problem, if developed countries want developing countries to buy VW-VBG130 the raw materials the production of solar silicon, we must follow to purchase the carbon emissions produced by developing countries to use the money to solve the technical problems of pollution links. “In addition to beyond this, the cost of photovoltaic power generation is still 10 times the thermal power, photovoltaic power generation cost has hindered the pace of development.

 

And core technology and raw materials out of the country, the production process of high energy, high cost of photovoltaic power generation than solar thermal power generation “has a core technology, production materials, glass and steel main needs” advantage. Power Norit’s products have been entered in the high temperature collector rapid production, the promotion stage, in refrigeration, industrial preheating and power generation, the application field and laid a solid foundation.

 

“Compared to photovoltaic, solar thermal power generation is more convenient and domestic power grid in docking, because the basic principles of solar thermal power and thermal power of the principle of similarity, while the domestic power network construction mainly thermal-based. As is the use of polycrystalline silicon photovoltaic cells convert light into other energy carriers, so the traditional test of a great power to regulate and control. “Investment consultant in the energy industry, said chief researcher Jiang Qian, solar thermal power will not power peaking, wrong peak of a great burden that is its absolute advantage.

 

Solar thermal power followed the larger the lower the cost of the law. Currently, the industry generally accepted scale is 1000 MW, the scale of 1,000 MW of solar thermal power plants can reduce the cost of electricity to the considerable advantages of 0.7-0.8 Yuan per kWh. “Solar thermal power generation of the technical issues has been resolved, but the Samsung IA-BP85ST Battery initial investment is very large, like the 1,000-megawatt-scale needs 20 billion of upfront investment, which is unbearable for some businesses, this area also needs the support of national policy.”

 

Solar Thermal for direct radiation in 1900 kilowatts hours per year / square meters, and the resource conditions of the world only the United States, Spain, Africa and China have. The United States and Spain has been the winner, while in China, solar thermal power generation project has just started, and there are large areas of light and heat resources, waiting for development. This is behind it, is undoubtedly a huge amount of the market.

 

According to the European Solar Thermal Association, published in 2005, a report is expected in the next 20 years, the global solar thermal power generation will be 16.4 billion Euros a year’s huge market. By 2025, the world’s total installed solar thermal power generation capacity will reach 36,000 megawatts; to 2040, solar thermal power generation to meet the 5% of world electricity demand. Relative to the global market, its domestic market potential for solar thermal power nikon EN-EL4 Charger generation is very large. It is engaged in electric light and heat of the Chinese Academy of Sciences researcher Ma Sheng Hung is estimated that by 2015, solar thermal power generation in China will reach 400-500 MW. After 2015, annual solar thermal power installed capacity will reach 300-500 MW.

 

“Photovoltaic and solar thermal power, advantages and disadvantages of each, who will replace who I do not think the future is the coexistence of two more, have their own applications.” Jiang Qian said that the relatively large-scale solar thermal power generation, while the PV is relatively small, suitable for families, residential area and so, therefore, the two are not exactly the same application. But speaking from the energy and technology, light and heat are more in line with China’s national conditions and long-term planning stage.

 

The current global use of solar heat into electricity installed capacity of about 700 MW, 1,200 MW of projects under construction, has announced the construction of the installed capacity was 12,600 MW, and these figures are updated weekly. View the current form of development, the rising star of the field of power generation is likely to surpass PV in the near future, become an important force in the field of power generation.

 

However, the rapid development of solar light and heat, can not do without the constant efforts of domestic solar energy companies. “Power Norit as a leader in the solar industry, independent research and development has always insisted, advocated by continuous technical research, make full use of solar thermal technology in the areas of life, and to further advance the industry. Do the same development, and fully enter the power generation only a matter of time. ”

Zinc-manganese battery development has undergone a long evolution, back in 1868, the French engineer George - Leclain Agency and charcoal powder with manganese dioxide as cathode powder, it would be pressed intoB150XG01 the body of porous ceramic cylinder and plug a carbon rod as cathode inverter set, with a zinc rod inserted solution for anode, electrolyte is 20% ammonium chloride aqueous solution, the battery container is glass, made the first zinc-manganese battery wet.

 

1886 Gass will use ammonium chloride solution, zinc chloride, gypsum and water, paste, and zinc for the battery Zuocheng cylindrical container, and seal with paraffin wax, which made the original prototype of the battery. Shortly thereafter, in turn flour and starch gel as the electrolyte solution, manganese dioxide batteries is greatly increased portability, as this battery of industrial production and extensive use of lay a good foundation. After 1890 years ago, this battery into a worldwide industrial production.

   

1870 years ago, has been introduced after amalgamation of zinc anode in Dell Latitude D820 Screen order to reduce self-discharge of zinc. 1877 on the carbon rod with wax dip to prevent crawling liquid carbon rod, to reduce corrosion on the metal collector.

 

1923 instead of using acetylene black powder, so the capacity increased by 40% -50% in 1945, electrolytic manganese dioxide battery application to discharge performance of zinc-manganese battery has greatly improved further. However, with the development of the times, ordinary alkaline manganese batteries can not meet the market demand.

 

As early as 100 years ago, it was proposed to do with a zinc anode, MnO2 to do positive, KOH or NaOH electrolyte to do, in the long process of research around four main issues: First, instead of flaky powder porous zinc electrode reduce the discharge current density and resolution of zinc passivity in alkaline solution is easy shortcomings; two anti-polar structure LTN156AT02 is used to improve the fill volume of MnO2 to match the capacity of positive and negative; Third, zinc amalgamation process and alkali fluid plus ZnO, solve the corrosion of zinc in alkaline solution; four sealing structure and materials is improved to address the phenomenon of climbing base.

 

Until after 1950 on behalf of the zinc-manganese dry battery in the developed based on the success of alkaline manganese batteries, It zinc as the anode, electrolytic manganese dioxide as cathode, electrolyte using NaOH or KOH, double the increase the battery performance. It is not only high capacity, also suitable for continuous large current discharge. Also has excellent low temperature performance, storage performance and leak-proof performance.

 

But in the early alkaline battery anode zinc powder in alkaline solution to control the volume, the battery was very large with mercury, using mercury in 2% -6%, the late eighties as the strengthening of people’s environmental awareness, set off a mercury-free alkaline manganese battery of fever, look for organic or inorganic inhibitor substituting mercury and zinc powder alloying elements (mainly Al, Bi, In, Pb) has become a major research direction. To the mid-nineties, mercury-free alkaline manganese manages battery market.

                                                                                                               

At the same time, from 60’s, on the rechargeable alkaline zinc-manganese rechargeable battery carried out extensive research, after 30 years of research breakthrough has been made, but because of its shallow depth of discharge, cycle life is short, not yet achieves commercialization.

 

Into the twenty-first century, alkaline manganese dioxide batteries are growing  HP Pavilion DV2000 Screen rapidly, a great alternative to ordinary zinc-manganese batteries and other batteries trend. The development of electric appliances at the same time alkaline batteries of high capacity and large current discharge higher demands. Therefore, future studies of alkaline concentrated in high-power heavy-duty discharge performance, improve battery capacity and increase the storage life.
