digital batteries

1, the price of materials of the drums continued to increase

Battery industry in China is currently facing a serious problem of “internal and external” troubled. As countries around the world to improve the requirements of environmental protection, and some developed countries have adopted the lead, cadmium, nickel and other production of nonferrous metals in the country to pass its own environmental pollution, which caused the price of lead electrolytic skyrocketed from 2003 to 4,500 yuan per ton rose to 13,000 yuan ton earlier this year, nickel price of 150,000 yuan per ton last year or so, now represent almost 450 thousand yuan per tonne. In addition, raw materials, cobalt, cadmium, the powdered natural manganese, zinc and other prices soar, to varying degrees. As the price of export products is well established with the signing of the contract, prices for commodities, the price can not synchronize to follow resulting in an export product, the greater the “loss situation. Production of household batteries coupled with fierce competition between companies, leading to their accumulation in recent years, low low to withstand the risk of these factors are closely related to each other the direct result of producing household batteries are moving forward with difficulty and would have reduced the scale of production and marketing in order to reduce the loss.

2, the impact of the export tax adjustment policy on reimbursement of the battery industry

September 14, 2006, the State Ministry of Finance jointly issued by five ministries and the “party products on the adjustment of reimbursement rates of export tax and the addition of the notice processing trade ban catalog. “According to the” Notice “of lead acid batteries, mercury oxide-policy export tax rebate has been canceled; Already in 2004, the Laptop battery has started exporting to the low rate of tax refund every year, and will be phased in rebate. The current lead-acid batteries, mercuric oxide, and nickel-cadmium batteries were included in the prohibited category into the Directory of processing trade, for inclusion in this directory should be levied on imports of goods, duties and import taxes.

According to the statistics agency, the reimbursement rate of export tax reduction of 1 percentage point each, equivalent to the cost of exports in general trade increased by about 1 percentage point; So the introduction of the refund policy of export tax would reduce the competitiveness of the export market of the battery, which will accelerate the battery industry to re-wash Brand, a number of competitive enterprises, small and medium enterprises will have a serious loss, or even its closure.

3, the green barriers abroad, the impact of the battery industry in China

According to the Official Journal of the EU “The recent adoption of batteries and instruction of the IBM ThinkPad R52 battery, the battery in the lead, cadmium, mercury objective fact, more demanding and requires commitment fees for cost recovery. REACH Regulations and guidelines based on ROSH improve registration fee and charge the battery test, a significant increase in the cost of battery production and the cost of export sales.

The European Union and other developed countries often establish “green barriers” have substantially increased the cost of exports of batteries, some SMEs because of economic reasons and technical reasons, to abandon foreign markets.

4, the fight against foreign-dumping and technical barriers to the impact of the battery industry in China

The battery industry in China after another 337 hit if the United States investigation of alkaline manganese batteries, the United States investigating the case of 337 lead acid batteries, the United States responsible corporate Ni-MH hp Pavilion dv6000 battery Chinese company charges, the United States and Japan, where the lithium-ion batteries and other intellectual property rights of patent cases, for the respondent, the consumption used a large number of Chinese companies involved in human resources, material and financial resources, the sales network has been seriously affected.

Recently, the battery industry in China also hit South Korea alkaline manganese antidumping sunset review, India, batteries dry antidumping sunset review. Increased by lead acid batteries and other products for more than a dozen anti-dumping, export trade battery has been severely affected.

Some anti-dumping cases and 337 businesses participating in the survey because they do not respond, which led to the trial the whole sector of the local market.

Responding to the lack of financing mechanisms under the current circumstances, the businesses under immense pressure.

5, the impact of RMB appreciation on the VGP-BPS2B battery industry 

The exchange rate of RMB 2005 1:8.3, by adjusting the current of about 1:7.5. Battery production in China in about 80% of exports, the appreciation of the yuan, while the export price of the battery difficult to increase the cost of exports has been considerably improved the battery to allow companies to decline economy.

6, transport costs

With the energy crisis, the transportation costs of the battery increases. In many parts of the Ministry of Communications goalkeeper lead acid batteries and nickel-cadmium batteries as the transport of dangerous goods, and forced recruitment costs, increase the burden on business and affect economic efficiency.

7, the battery industry, the situation serious occupational hazard, environmental protection and management of investments to improve

Lead-acid batteries and nickel-cadmium alkaline battery positive and negative main raw materials are lead, cadmium, nickel and other non-ferrous heavy metal compounds, particularly metal ions cadmium and their toxicity and poisoning have an important role in the manufacturing process raising dust, more sewage and waste pollution, through various ways by the human body after making the deposit continue to play a role, eventually leading to the ‘poisoning of the bone in bulk, the hematopoietic and renal functions. Battery contaminated soil or water, and again by growing plants, vegetables and invades the human body in violation of depth.

To summarize, the toshiba PA3191U-3BRS battery companies in China are facing difficulties, and that the Chinese Battery Industry Association will actively guide companies to adjust product mix, diversify the direction of development, while Enterprises should strengthen the technical, process innovations and equipment, improve the use of raw materials and improve resource use, reduce as much as possible because of higher raw material adverse effects; actively improve the production process, accelerate the pace of eliminating backward production capacity once the transition to efficient production, ecological and energy efficient way of promoting cell cell industry for sustainable development.

Lithium-ion rechargeable battery of the 20th century, early 90s has been officially practice in less than 20 years, the ability of a rapid increase in the rapidly growing market. It is estimated that in the future be extended to the use of electric vehicles and portable power environmentally friendly storage and other areas.

Lithium-ion rechargeable Laptop battery status and challenges and future directions of development of an interview with the practical stage for many years before the study in the development, known as the father of lithium Parents Chief Executive of Sony, Executive Director of the Spanish-American thread. (Interviewer: Security Hideo)

Q: Lithium-ion rechargeable batteries are used to expand the way up?

West: 90 years in the 20th century, the import issue, we once made home video cameras, and MD players, AV products such as the application of lithium-ion rechargeable battery goal. But this time a very small production alone can fully satisfy the market simply did not anticipate that the IBM ThinkPad T40 battery will become consumer products.

However, soon begin using lithium-ion laptop battery, this market began to grow rapidly. We learn that at that time played a computer makers “from New York to Los Angeles route five hours without charges,” the ads have played an important role. Another period of universal prosperity and promoting the development of lithium-ion rechargeable batteries for notebook computers, and cell phone.

In the 21st century, lithium-ion batteries has begun to have digital cameras, power tools (PowerTool) and game consoles such as adoption. The face of the building society low-carbon future requirements in the time it is estimated will use in future hybrid vehicles, electric vehicles, industrial and domestic fixed power expansion.

Lithium-ion rechargeable Dell Inspiron E1705 battery with technological development, its energy density is increasing each year. To ensure safety measures can be combined. These measures have contributed to market expansion.

Q: To improve the energy density is the key to what? Energy density of the future will be raised?

West: to improve the energy density of batteries, there are two ways. Firstly, to produce electricity without reducing the contribution of the Ministry of material, such as thinning of positive and negative electrodes of the collector body and the diaphragm to reduce the binder and conductive auxiliary material. In short, through the battery designed to improve. But the limits of this approach.

Another method is to increase the active electrode (positive and negative) of the unit of weight or capacity per unit volume. The material development has long been underway. LiCoO2 cathode of lithium-ion rechargeable hp PP2182D battery early start to close at nearly the theoretical limit of the ability to use, totally dependent on improving the performance capacity of the battery anode.

For example, the initial negative lithium-ion rechargeable battery using carbon (coke), its capacity 250mAh / g around the initial charge, discharge efficiency, but about 80%. And now, the negative carbon (graphite) the ability to infinitely close to the theoretical capacity of 372mAh / g, the initial efficiency of over 95%. The energy density, respectively, in the 200Wh/kg early 80Wh/kg to 600Wh/kg present 220Wh/kg.

However, the negative carbon (graphite) under the condition of the sony VGP-BPS2A battery capacity has now almost reached the theoretical limit, it is imperative that the development of a new generation of negative. Other material of tin (Sn) and silicon (Si), the old theory, three times the capacity of graphite, which is 10 times higher than in graphite.

On the other hand, the cathode material in terms of capacity and basic living is not progress. Capacity larger than LiCoO2 cathode are LiNiO2 is expected at the cathode is increased by 10 ~ 20%. However, LiNiO2 the issue of security is very broad, is virtually useless.

Recently, some products are used in lithium-ion battery voltage toshiba PA3399U-1BAS battery to 4.2 V or more, such as 4.4V, the value of discharge current is the same as the energy capacity (Wh) increase cathode material.

As indicated above, at least in terms of negative from the material capacity is correct.

Q: To improve the energy density, should pay attention to what is the problem?

West: using demand side is not necessarily limited to capacity. Emphasis on output characteristics of certain purposes, such as power tools, while the satellite with the auxiliary power focused on the characteristics of the cycle. Sometimes requires cycles to reach 15 million times, far more than the apple iBook G4 12 inch battery from the computer.

Must take to meet the above requirements of materials and design methods. Of course, all properties have excellent battery is nonexistent. The emphasis on performance, depending on what is to decide what battery to use materials and adopt design.

And, not only to meet these multiple requirements, the safety of this important and indispensable element should be compliance. Consequently, the resulting safety factors must be considered and what is the nature of matter and how to develop materials to reduce these factors.

For example, if, as mentioned above, to SI as a negative, the negative capacity of carbon materials can reach more than 10 times, but also consider other features (such as load characteristics and the characteristics of cycle) and security. In addition, if we adopt the SI followed the cathode material of origin in order to maintain a balance with the negative, positive living matter worth increased to 10 times the thickness of coating. But in fact it is not possible.

Given this, only individual to improve the negative, not to improve the characteristics of the TravelMate 290 battery itself, but also need to re-consider the positive electrode, electrolyte and separator and all other materials.

Finally, to ensure the security problems faced by developers face. Top of battery power is sealed in a narrow space limitations. And use a bit of a slow release of energy. Sometimes, however, for some reason, a sudden release of energy. Cause an accident.

Devoting more resources to the energy released could be higher, thus a higher risk. Therefore, the higher the energy density, safety measures, the most important.

Increasing the energy capacity, with the corresponding security VGP-BPS2B measures essential for development.

Q: What are the essential safety measures?

West: As already mentioned, due to higher energy density, the greater the risk, so that security issues more important.

No single cause of the accident. Need to understand the positive active material, negative active material, electrolyte, separator and a satchel and all others in the process of loading and unloading of the moving mechanism and its impact safety.

Recently, the cost of increased competition, the technical side and the seller proposed to reduce the cost of production sites have become more demanding. Although you may think replaced by cheaper materials and shorten the manufacturing cycle and other methods, but the technical aspects to take into account those pairs of Dell 6Y270 battery performance, particularly in security, the impact for the maintenance of a place can not make concessions attitude.

On the other hand, the concern is not without the aid of the party not in compliance with the design of the battery using the designated location request. I also heard that because of the construction machine side strongly demands for fast, its temptations, the charging voltage is designed to limit the phenomenon of over 4.2 V is also beginning to emerge.

In the lithium-ion rechargeable battery run time, the battery technicians and sales personnel to use the side with an introduction to the technical team, clearly tell everyone what to do and not do. Now, sales are run by companies, fewer and fewer such scenes.

Q: How to improve the resistance of young technical staff?

West: Lithium-ion rechargeable hp 367759-001 battery with the original battery is different from other chemicals, non-electric material elements of knowledge but also wide. These include organic chemistry (electrolyte, binder, diaphragm), polymer chemistry (divide, linking, gel electrolyte), metal (positive and negative collecting agency), ceramic (positive living material), the carbon materials (anode), etc..

In addition, lithium-ion rechargeable toshiba PA3534U-1BRS battery applications wide range of fields, use the method (charge and discharge conditions) are also diverse, so also need to understand the application of the machine a little. Therefore, can not lock us in “I’m positive expert, a narrow zone. In command of a wide range of knowledge (even if you can sit in the cars), then, should be established areas of expertise.

Q: Could you tell us about the problems of system management.

West: I hope that manufacturers of batteries, remember that more attention should be given regarding the cost principles of quality and safety. Otherwise, no matter how to improve the energy density and output characteristics, eventually becoming a mirage.

You want to use lithium-ion rechargeable batteries and battery production in the exchange of technical personnel to go to learn more about lithium-ion rechargeable apple PowerBook G4 15 inch battery is used. Of course, this issue is not only machine, hand building, the designer of the battery must also pay attention.

1. Motor fuel battery hydrogen to promote the constraints

While battery vehicle hydrogen fuel in protecting the environment has a great advantage, but it is still in early stages of development. The main factors limiting the development are:

(1) Production costs are high: At present, the source of hydrogen is natural gas in general and biogas. In addition, hydrogen and oxygen by electrolysis of water extracted hydrogen separation. The energy can produce electricity from coal or nuclear reactors to generate. Because the extraction of hydrogen consumption of other energy needs, so if the use of coal, natural gas, methane and other hydrocarbon fuels to extract the hydrogen, it will emit greenhouse gases emissions. Using wind and solar power can solve this problem, but the high cost of such a development mode, causing the cost of hydrogen fuel Laptop battery car. In addition, a number of ancillary facilities such as construction of refueling hydrogen have to charge a certain time.

(2) The energy density of small and inconvenient storage and transportation: problems of storing hydrogen fuel, there are leaks and gasification of issues, including the blast, quenching, when the fuel of Other issues to resolve.

In conclusion, low-polluting hydrogen fuel, however, but the difficulties of storage, there are leaks and gasification of issues, including the blast, quenching, when fuel and other issues to resolve. There are many methods of producing hydrogen, but only in the settlement of its costs, storage issues such as possible after the batch used.

c. The strengthening of the hydrogen and fuel batteries as the core system of energy distribution of hydrogen

Because hydrogen and fuel battery has many advantages and features of decentralized energy supply, thereby strengthening the nucleus of hydrogen and fuel battery system of distributed energy has become the focus of research future international and development. The current formula of hydrogen and fuel batteries as the core of the system tends distributed energy development is the use of renewable energies, combined with hydrogen as an apple A1185 battery carrier, to fuel batteries as a tool conversion of energy to enhance the development of renewable energies.

d. attention to the economic development of hydrogen-related environmental issues and security

While hydrogen itself is a kind of green energy, but in the process of using fossil fuels, hydrogen production, storage technologies, if properly, there will be leaks CO2 in the atmosphere caused by rising greenhouse gas emissions. Hydrogen production, storage, transportation and use of fuel batteries to hydrogen, it is inevitably the process of hydrogen leakage. When released into the immediate environment of the hydrogen reaches a BATCL50L certain concentration, may be encountered by fire or explosion, where a strong chemical reaction, causing casualties and property losses. In addition, leaks in the atmosphere of hydrogen with the reaction of atmospheric ozone, the destruction of the protective layer of ozone in humans. Therefore, we must strengthen the safety-related hydrogen technology and the detection of hydrogen sensor, the potential accident scenarios on research technology.

e. effective to encourage companies to participate in hydrogen technology and fuel batteries, industrialization and commercialization of evolution

In accordance with the laws governing the functioning of the market economy, hydrogen technology and fuel batteries as the technology is mature, with the case of price competitiveness to win the contract to replace fossil fuels traditional and a number of relatively low efficiency use of methods of energy Dell HD438 battery conversion. It will be possible for firms to participate effectively in the development of hydrogen delivery prices competitive preparation, storage, transport and application technology and this was also the final decision of hydrogen to replace fossil fuels traditional key.

f. use government subsidies to promote hydrogen

To promote the use of the hydrogen society of the energy required to inform the public of the merits and use of energy security of the hydrogen to promote the understanding and use of the hydrogen energy. Meanwhile, the state should be presented to a policy of encouraging more efficient, for example, the State should be the use of VGP-BPS2B hydrogen government subsidies in order to effectively promote research on hydrogen energy and the development and implementation of the system.
