China Zinc-manganese dry battery of mercury in alkaline 1% to 5% of 0.025% neutral dry VGP-BPS2A VGP-BPS9A batteries, has seriously overstepped the country each year for the production of mercury batteries is once up to 100 tonnes per year of mercury pollution as much as content. Was a major pollution and disturbing.

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.

Types of resistance of electronic equipment is an essential component in the context of the global economic crisis, manufacturers of resistance to rising production costs and declining commodity prices double pressure, fierce market competition, manufacturers are continually squeezed margins. Despite the difficult challenge, but the global consumer electronics products continue to increase, as DVD players, digital cameras, MP3 players and mobile phones, computers and peripherals, a digital A / V equipment and the VGP-BPS8B VGP-BPS9 automotive electronics products, strong sales and demand to maintain the strength of the Chinese market. Manufacturers are required, since 2010, all high-end High-boxes (STB), high-definition television and automotive electronics production line will be the resistance of the primary driving force. Mobile phones, wireless LAN and mini-cameras for SD cards will stimulate the market, smart growth resistance mad.

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.

With the cell phone technology, the mobile phone battery was a “regime change”. In the first NiCd and NiMH Li-ion battery, and then Li-ion polymer batteries. Greater energy density, smaller size, greater life expectancy of mobile phone batteries strong support for the development of mobile phone. The mobile phone battery following are the key technologies and important parameters to make a brief review. IBM ThinkPad R52 battery IBM ThinkPad T40 battery

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.

1, lithium-ion battery separator Overview

With lithium batteries with high energy density, long cycle life, light weight, small size and other characteristics, but also a reliable, safe and can quickly charge and discharge, etc., to become the new power technology in the recent years, the hot spot of research in the field of high power and high-energy folk reserved. In the structure of the lithium battery, the inner membrane is a key component of the. Diaphragm plastic film is able to isolate the Laptop battery positive and negative, to prevent short circuits; also be overheating of the battery, through closed-cell function to block cell in the current conduction.

Depending on the physical and chemical characteristics, the lithium battery separator materials ion can be divided into: film weaving, non-woven membrane (non woven), microporous membrane, and composite membrane, paper separator material various film categories. Polyolefin materials have excellent mechanical properties, chemical stability and relatively inexpensive, and therefore, polyethylene, polypropylene, microporous polyolefin membranes for lithium-ion batteries will be used as a research and early development of lithium – ion IBM ThinkPad T41 battery separator. Today, the marketing of lithium-ion battery separator is still microporous polyolefin membrane. In recent years, solid electrolytes and gel began to be used as a specific component, while playing the role of electrolyte and battery separator is a new technology.

Cost Li-Ion Battery Battery separator reflect the cost of a / 3. Membrane determines the performance of the interface structure of the battery resistance and so a direct impact on the battery capacity, the cycle efficiency, and safety features such as the membrane of high performance in the improvement of the overall performance of the battery has an important role. At present 60% to 70% of the market for membranes, especially in wet bi-oriented process, because the wet, bi-lateral vertical stretch more balanced. It is mainly used for the method of high-end diaphragm wet, dry, has been applied in the low range.

2, diaphragm production process

The current market-based lithium-ion Dell Inspiron 1420 battery separators are mainly made of polyethylene, polypropylene based polyolefin membrane, including the PE single layer, single layer PP, three-layer PP / PE / PP composite film. Polyolefin membrane current process of production under dry and wet divided into two categories, while dry process design can also be decomposed into one-way and two-way stretching process.

Dry-way stretching process is the production method of hard-elastic fibers were prepared by a low degree of crystallinity of highly oriented polypropylene or polyethylene film, high temperature annealing to achieve a high degree of crystallinity of film orientation. This film is stretched at low temperature, before the formation of mania and other defects of micro-enterprises, and then opened under high temperature so that the defects form a pore. This approach was first seen in USPatent3426754 Patent U.S. Celanse 1970 for the production of mono-layer membranes of porous polypropylene. The process after decades of development in the United States, Japan is already very mature, and now the U. S. Celgard Inc., Japan’s use of these boats UBE unique production PP, PE, and three PP / PE / PP composite film. This method of producing the BATBL50L6 porous membrane has an elongated structure, because it covered a stretch event, the horizontal force of diaphragm relatively poor, but it is not conducted due to the transverse tensile, transverse almost no shrinking heat.

Due to the protection of foreign patents and constraints of intellectual property, the domestic one-way membrane traction determined by industrialization progressed very slowly. China has already started in 2004 in this patent relates to technology and foreign patents difference is that in the polypropylene has a crystallization promoting effect of adding nucleating agents, and agent additive for oil has accelerated the rate crystallization during annealing. The technology is now used in Hangzhou, a production line, using a method how to stretch the production of PP single-layer diaphragm, has made this type of membrane on the market.

Wet-phase method of separation is also known as the separation of thermally induced phase, the high boiling small molecules as pore-forming added to polyolefins to merge into a uniform, then the cooling phase separation occurs The stretch after the ecprice extraction of organic solvents with small molecules can be interconnected prepared material of the microporous membrane, the material widely applicable. Adoption of the law, a company representative Asahi Kasei of Japan, Tonen and the United States Entek, currently used primarily for single-layer membranes of the PE. Wet bi-directed path to produce the membrane after a double meaning because of tensile strength of high vertical and horizontal. China Foshan Plastics Group was established in 2004, using a wet process production of two channels by membrane stretch production line PE by the end of 2005 has started selling products on the market.

3, the major international manufacturers diaphragm

Portable power tools, mobile phones, laptops, video camera lithium rechargeable ion batteries, power tools, small batteries used mainly polyolefin membrane, technology and markets are already very mature, the largest supplier of Asahi (Asahi Chemical Industry), U. S. Celgard and Tonen (Tonen Chemical), Asahi Kasei 5 in the main supply to the membrane over Sanyo, while the Celgard and MBI is a leading provider of BYD; With Sony, SDI, LGC and other clients, Tonen Chemical to become the world This membrane third largest supplier. The United States and produced three UBE Celgard polypropylene / / polyethylene polypropylene (PP / PE / PP) composite film. This type of material characteristics of the membrane is its higher resistance, lower cost, but also in the temperature of the internal hp 367759-001 battery is high, PE melt at 130 ℃ or so, when, while the high melting point of PP (150 ℃ or so) to form the obturator membrane, so that the battery internal circuitry, greatly improve the safety performance of the battery, but the complicated manufacturing process, and these are particularly difficult to achieve Ultra-thin 16um. Asahi Kasei, Tonen, the United States Companies ENTEK such that only the polyethylene (PE) membrane. This type of membrane material because it is single-PE, and therefore the cost of production but the production of ultra-thin membrane under specific conditions 16um, so popular with major battery manufacturers such as Sanyo, Sony, Panasonic, Maxell, etc. favor.

4, the internal status of development of membrane industry

With the development of lithium-ion battery industry, the market on the separator internal lithium battery lithium battery has gradually entered the ring, Xinxiang, Henan, China and the Sino-Kuwaiti Douglas.Ryan Technology, Foshan Jin Hui Hi-tech Taiwan and raised the money represented by the manufacturers internal lithium ion toshiba PA3421U-1BRS battery separator to grow rapidly in the years, the diaphragm, compared with imports of their products, the import price gap is just 1 / 3 ~ period from 1 / 2 mineral products is also relatively short, but the thickness of the inner membrane, the strength, the absorption hole can not be get the overall balance, and batch production volume is less stable, manufacturers of lithium battery internal chose the great majority of the imported membrane. Therefore, research and development costs, production process is simple, the adequate opening size, high porosity, mechanical strength to meet the requirements of the porous polymer separator to improve battery performance and reduce costs Battery has an important practical significance. How to further improve the membrane quality indicators is the battery industry in China is now pressing problems.

5. Lithium-ion battery development trends of separation

Battery separator is mainly the development of lithium-ion batteries with the changing needs and continue to grow, in terms of volume, lithium-ion batteries are moving in the small and large two distinct meanings. In some, such as mobile phones, digital cameras and other electronic products to meet the beautiful and simple formula to bring the application on the factory batteries apple A1060 battery was very low. In pursuit of high energy density, the small size of the electrode can accommodate more equipment, battery manufacturers are seeking to divide the thickness of the thinner, the better. Small cap is a challenge because of the need to make a thin membrane, but to be able to maintain the capacity of the original battery, the cycle efficiency, and safety features and more power, more design easy.

In contrast, electric bicycles, electric vehicles and power tools used by battery power, to achieve high capacity, high power, usually a battery needs to use dozens or even hundreds of batteries to the concatenation. Because lithium batteries have the danger of explosion, the safety diaphragm is important. Due to become increasingly large, technically demanding more efficient and reduce emissions of greenhouse gas emissions, higher power.
