Daily living cells because of low value, high consumption, small size, no risk of pollution, intuitive and direct environmental and other reasons, often difficult to attract people’s attention. The battery is exhausted, it is also used to readily discarded, resulting in spilled all over the batteries used. As everyone knows, they seem to forget the battery due to mercury-contaminated materials that spill into the nature, cumulative, over time the outer layer of the corrosion of metals, mercury and other hazardous substances will gradually stack overflow in the ground or in the rain dumped in rivers, groundwater. If the burning of garbage, waste containing mercury in the waste batteries will be in the form of mercury vapor in the atmosphere. According to tests, one on the 1st of mercury-containing batteries, can we square meter of land to lose value. In the environment of mercury absorption by plants through respiration of animals, drinking water, through the food chain, directly or indirectly enter the human body, and long-term accumulation in the body difficult to take, damage to the nervous, hematopoietic function, reduced immunity, victims of kidney and bone. Therefore, waste batteries free throw leaving the environment in the long term, potential hazards, if the battery industry to environmental hazards, the characteristics summarized in six words: “the batteries, though small, pollution becomes larger, centralized production and decentralized, pollution, short-term use of long-term damage. ” IBM ThinkPad T43 battery  IBM ThinkPad T60 battery

Batteries contain heavy metals – zinc, lead, cadmium, mercury and manganese. Experts said the test, a button battery can contaminate 600,000 liters of water, one on the 1st Battery rot in the ground can make a square meter of land loss of use value, how can we ie to produce the number of discharges; centralized and decentralized pollution; Short-term use, long-term contamination.

Manganese accumulation of excessive amounts of manganese in the body caused by a neurological dysfunction, an early manifestation of an integrated sexual dysfunction. Heavier people have fat legs, Shen, language, monotonous, dull expression, emotional apathy, often accompanied by psychological symptoms.

Zinc salts Zinc may precipitate the proteins, stimulate the lining of the movie. When the concentration of water in the history of more than 10-50 cents / L when carcinogens, may cause chemical pneumonia.

Lead: Lead a major role in the nervous system, circulatory system, digestive system and liver, kidneys and other organs may inhibit the synthesis of hemoglobin metabolic process, but also directly on the cells mature red blood exert a great influence on children’s and young infants, it will lead to delayed physical growth of children, chronic lead poisoning can cause mental retardation in children.

Nickel Nickel powder dissolved in the blood, to participate in the movement of the body, it is highly toxic, can damage the central nervous system, causing abnormal blood vessels, severe cases, cause cancer.

In those mercury, heavy metals pollutants is most notable for a long time, China in the production of dry batteries, it is necessary to attach a toxic substance – mercury compounds or mercury, our alkaline batteries mercury content reached 1-5%, 0.025% neutral batteries dry. Mercury neurotoxicity was evident in most of the endocrine system, immune system, also have a negative effect in 1953, took place in the Japanese island of Kyushu, which shocked the whole world new cases of Minamata disease, give the man sounded the alarm of mercury pollution. 

Each year we produce over 10 billion batteries, hazardous kept saying it is not bad depending on the brand, do not throw error! I think the problem has been discarded batteries in critical condition, our soil, rivers and lakes are completely destroyed, Zaiqu governance makes no sense! Because it’s too late! hp Pavilion dv4 battery  hp Pavilion dv6 battery

I think the specific method should be as follows:

1, from the manufacturer of the battery is charged battery recycling, production and how many departments how, with three above-mentioned co-guardianship, the quasi-military management;

Secondly, the implementation of the marketing system monopoly, sellers must return, or can not be sold, and violators face heavy penalties! With the process of monitoring the monitor!

Thirdly, the provision of the Inspector of State for the protection of the environment, high prices exhausting;

Fourthly, to accelerate research environmental protection of the battery, the rewards of technological progress;

5, to raise prices to double to ten times for recycling, environmental protection and scientific research, while the role played curb consumption;

6 for one third the price of recycling batteries new batteries;

7, called upon all citizens can not use the A1045 A1060 battery is completely free to use, consume less to consume less, certainly not abandoning the old batteries.

Manufacturers in the industry believe that the prospects for market development in 2010, resistance to the interest, demand should be strong in the market space in 2010, the resistance will continue to increase, the annual growth rate be maintained at about 20%.

Since reform and opening, China’s national economy and the socialist construction has developed rapidly in various fields has achieved great success. As an electronic product manufacturing base, the resistance has also been the rapid development of industry success. According to statistics, the total production of the resistance from 1988 to 8416 million, based on a rate of annual average increase of 12.68% for 1996, reaching 27.718 billion, is 88 times the annual production 3.4, the effective production PA3421U-1BRS PA3534U-1BRS capacity of about 47.15 billion, turnover reached 8.84 billion yuan, the export volume reached 8.8 billion euros in 2008, the total delivery of China has been promoted to the resistance 708 billion more than in 2005, 410 billion has been an enormous increase in the strength of the market at that date amounted to the total world supply in three. Expert analysis, from 2005, the production scale in China resistance rate of 20% annual growth at the end of 2009 the total output resistance of China about 850 billion ‘euros.

More than 20 years, resistance in our country has greatly improved the quality of products, including chip resistors to become the protagonist of market development. Because the resistance chip resistor fully mastered the techniques of production, and can be applied to the electrode extreme plating technology, product performance to achieve the level of similar foreign products. At present, China’s satellites, missiles and other aerospace technology have been applied to our own production of chip resistors, resistance and production accounts for 85% of total production, manufacturers increasingly produce the transition to chip-type products. In the global mobile communications, computers and peripherals, digital consumer and automotive electronics industries, the demand on resistance to chip, driven by local Chinese suppliers to increase their investments in such resistance, especially A1045 A1060 portable electronic devices demand a small increase in resistance. In addition to chip resistors, the local Chinese manufacturers also produce plug-type resistance, such resistance has been widely used in consumer electronics, industrial equipment and toys for children. The industry will continue to predict the future plug in resistance to the field of high power, the market will remain stable. Furthermore, as aviation, aerospace and military demand, China’s output resistance metal film will increase.

In the fiercely competitive market, batch after batch of resistors manufacturers, such as Chengdu, the positron countries limited liability company, the Shenzhen Electronics Industry Exhibition Co., Ltd, Nanjing Heng Electronic Technology Co., Ltd., Xianyang Qin Special factory Electronic Components, Guangzhou City Kin Yuen Electronics Co., Ltd., Sichuan Kai Hing Electronics Co., Ltd., Shenzhen Electronic Co., Ltd., Mellon is rejuvenated through the reform of restructuring, technological innovation, changes in production technology have emerged rewarding. Many manufacturers not only obtained the certification of ISO9000 quality system, product quality and management of the company reached a new level, but also international standards that ensure the quality of our product and to promote resistance exports of resistance have a larger role. I think the product strength of our country is comparable to foreign products when there is a huge competitive advantage. Dell Inspiron 1525 battery  Dell Inspiron 1526 battery

Foregoing, the resistance to the Chinese industry to all industries, electronic components, after several years of hardening and construction, has developed into a large scale, professional range of varieties of the base system to help the industry.

Recalling the rapid development of 20 years, the future is full of opportunities and challenges of the future, we must seize the opportunities, so that industry has a greater resistance development. 3G and developer of high definition market, market demand will eventually promote resistance from China to enter a new phase. 2010 to become the market of China, the rapid development of resistance as a historical moment can not be missed.

Batteries mobile phone technology

The battery technology application to a large extent by decisions based electric technology development. With the continuous development of technology, batteries, NiCd and NiMH batteries gradually decreased at the same time, Li-ion battery production has risen steadily, and the Li-ion polymer batteries have started to occupy a certain market share.

In general, batteries have two electrodes anode and cathode. Anode to release electrons and produce a lot of holes, the polarity is positive accumulation of cathode electronics, the polarity is negative. Pricing, the current in-house flow of the anode cathode discharge to the contrary, the current outside the cathode to the anode, the power load. Parameters common battery performance are defined as follows: If a battery is fully charged after the discharge capacity after an hour the whole space, then the current rate of 1C; to recharge a battery or batteries pieces full of tension ( 4.2 V for example), then through the discharge power is empty (eg, 3.0 V) is called a charge-discharge cycles, when the battery capacity to maintain a valid value (like amount of charge up to 80%), the battery charge and discharge cycles can increase the number of known life cycle of the battery.

1. NiCd and NiMH batteries

NiCd batteries use cadmium as the anode, the cathode NiOOH. NiCd batteries have a life cycle longer, better temperature characteristics and high density of the battery. As a battery faster, Cd pollution material is relatively heavy environmental and density of the battery must be further enhanced, while NiCd battery is difficult to increase the capacity and will be disposed of market applications.

NiMH batteries using MH as the anode, cathode and NiOOH. NiMH battery is charged and the discharge characteristics, and cell density than nickel-cadmium batteries has increased by 30%, and are more environmentally friendly. NiMH better safety performance in itself, it was anti-overload protection and self-discharge capacity of healing, compared to Li-ion batteries, it does not require additional protection circuit and board containing PCBs. NiMH batteries have many advantages, but in the charging efficiency, battery and the density of leakage current of these areas need further improvement. 338794-001 361742-001

2. Li-ion batteries

Li-ion batteries using carbon or graphite as the anode and the metal oxides or Co / Ni / Mn cathode, organic, or an electrolyte solution to polypropylene as insulation. As the material, Li-Ion batteries must be placed under some form of cans solid, if pressure is good, and the shape is fixed.

Li-ion batteries provide 3.6V operating voltage is generally more stable performance. Its power density is very high self-discharge of the leakage current is small, large capacity and a small external. In addition, Li-ion batteries, long battery life, typically more than 400 cycles of loading and unloading, and the life cycle of work and stable performance. Figure 1 show the different life cycle of the Li-ion battery under the 1C discharge voltage and the curve of time. VGP-BPS5 VGP-BPS9A

When the Li-ion batteries in cell controlled by the field of traditional chemistry, in improving the energy density at the same time, the design of the battery and the chemical change also makes the key parameters of the battery can be improved. Li-ion battery has been applied in many system designs, it may be well positioned to meet the energy needs of the system.

Of course, Li-ion batteries is volatile and flammable material composition, and therefore the design of the battery, safety is an important criterion.

3. Li-ion polymer battery cells

Li-ion polymer batteries batteries batteries with Li-ion battery similar to the use of carbon as the anode, metal oxides as cathode, gel electrolyte membrane using the gel as an insulator. Li-ion polymer batteries have greater capacity and higher energy density. With the Li-ion batteries similar to its self-discharge of the leakage current is low. However, Li-ion polymer battery of stability is not good, so it needs to operate more stringent. A1060 M8403

Li-ion polymer battery technology to significantly improve the energy density of battery life, temperature and duration of conservation, energy efficiency of the battery is very high. Appearance, Li-ion polymer batteries using plastic containers, compared to Li-ion battery shell metal has a definite advantage, but the Li-ion polymer batteries are also easy to force expansion, so the production of materials, flexibility of error for a strict control. From a security standpoint, Li-ion polymer batteries and battery fever electrolyte leakage problem has been a real headache. Because Li-ion polymer battery is easy to develop, its reliability needs further improvement.

In short, there are many manufacturers in the continually improving Li polymer battery technology, and supply-ion batteries with the same service prices. However, the stability of the polymer has not been verified, but also be further improved and developed.
