Mercury-free button batteries global leader in China's first

Mercury-free button batteries global leader in China's first In June 2009, a news aroused our attention: Sony Corporation announced Laptop Battery the six models of mercury-free alkaline button batteries (LR) of the commercialization plan, which means that Sony's mercury-free button batteries will be fully the market.

In fact, as early as eight years ago, China's New Leader Battery Co., Ltd battery business had been a breakthrough ahead of other countries that plagued the world's problems, and was the first conducted a large-scale production.

Mercury batteries inside has a great harm to humanity, because the battery inside the mercury on the brain and nervous system toxin significantly IBM Laptop Battery interfere with the normal work of nerves, fetal or infant exposure to high doses of mercury can cause mental retardation, cerebral palsy, hearing impairment, or vision loss and so on. Even exposure to low doses of mercury, may also affect children's healthy development, it may allow them to generate attention, action coordination, language skills, visual-spatial, and text memory problems. For adults, chronic mercury poisoning can lead to memory decline, seizures, vision loss, and the hands, feet mean paralysis, as well as fertility and the pernicious effects of blood pressure. Increasing evidence also shows that mercury exposure may increase heart disease.

And because the battery of a high frequency of use IBM 92P1089 Battery and universality, making the threat of mercury-containing batteries become more prominent. It is reported that a New Zealand-style micro-mercury alkaline batteries can be contaminated water is 600,000 liters, equivalent to the amount of drinking water a person's life.

In other countries, more than a decade in Japan and the United States, Europe and other well-known battery manufacturers of mercury-free button cell mercury-free overtaken by a large number of studies. However, there are technical problems are not resolved, there is no one company can successfully produce mercury-free alkaline button batteries, resulting in the global market has been the use of mercury-containing alkaline button batteries. Button cell 1 billion each year by the production and use, so that China and the rest of the world people are still faced with the danger of IBM 92P1087 Battery mercury exposure.

While all research work to a standstill, when this problem by the new company's break-qing Li Dade. In this regard, China Battery Industry Association and the American environmental groups have given a high degree of recognition and evaluation, considered to be the cause of the world's great contribution to environmental protection. With the invention of this technology, China has become the world's first mercury-free button batteries cracking problems of the country.

It is understood that the reasons for mercury button batteries, mercury is used to block the battery anode zinc cream with pieces of metal anode contact, because such contacts will produce hydrogen gas, leading to cell swelling deformation, leakage or even explosion. Early mercury button cell battery leakage problem also exists, which is affecting performance, battery life and the use of the most fatal flaw, but as early as the late 70s of last century, mercury-containing button battery DELL 08K8194 Battery leakage problems, they have been passed to the original usage of "Punch made with thin steel plate and then nickel-plated or gold," the negative cover, replaced by a "from nickel, stainless steel, copper composite rolling made the 'composite metal band,'" made negative cover, and other related improvement measures to be effectively controlled.

The purpose of this patented invention, is to maintain the original mercury (ie mercury) button batteries of anti-leakage performance of the same, based on mercury-free button batteries.

The patent on October 19, 2001 by the State Intellectual Property Office to the patent application, and in October 2, 2002 announcement was authorized by the patent No. 01,234,722.1.

With the mercury-containing button cell battery usage and the growing volume of waste, waste batteries, mercury pollution of the environment becoming IBM 08K8196 Battery increasingly serious. Thus, out of need for environmental protection, button cell battery manufacturing industry has been eager to resolve the battery in the mercury problem. In this patent application, Sony, Toshiba, Hitachi, Panasonic, Seiko, etc. at the button battery R & D and manufacture of industry-leading position among the Japanese companies, are mercury-free button batteries to resolve the issue for a variety of attempts and efforts to put forward all kinds of technology solutions. All of these technical programs are committed to address the mercury-free leakage caused by the new problem, but has failed to effectively meet the mercury-free technology and anti-leakage effect of both. Therefore, this patent application until a few days ago, button cell battery manufacturing industries can in fact have not effectively address both mercury-free and also the technology of anti-leakage problem, and thus mercury-free button batteries have yet to really realize the IBM 92P1102 Battery industrialization and market access.

This patent research and development through the use of unconventional ideas, successfully resolved the distress button battery manufacturing industry for many years technical problems. Before the date of this patent application, all address the issue of mercury-free technology to improve the program, are in the existing technology base in order to mitigate the negative climbing (ie, leakage) speed commonly used by nickel - stainless steel - made of copper to suppress three-layer composite plate made of metal anode cap based on an improved, all of which improve the programs do not relate to the negative laminate cover any change in the structure itself, even in the knowledge that negative covered laminate structure forming the dislocation occurs and thus damage the coating used in its IBM 92P1077 Battery suppression of hydrogen produced by indium or tin plating and cause the battery case of the inflatable and the leakage is still only proposed many other complex "plugging" program, but did not give any regard to the availability covered by changing the negative laminate structure to solve this problem the technical inspiration.

And this patent is another way, its R & D and set aside the idea of super-normal manner by the existing technology made of three layers of metal composite plate anode covered with a laminate structure, but directly by the metal plates or sheet made of stainless steel anode on-chip "in gold, silver, copper, tin, indium and other tests and found that the negative on-chip indium or tin-plated success in controlling the battery anode zinc cream in contact with the anode film produced gas, together with the improvement of raw materials and formulations on the success of to produced the mercury-free alkaline zinc-manganese, zinc / silver manganese button-type batteries. based on the discovery, the completion of the present IBM 92P1073 Battery utility model. "

In this patent the technical program, in order to better in the negative on-chip indium or tin plating, and the elimination of a single coating of the pinhole prone to problems presented in this patent by iron plates or stainless steel sheet made of negative film naked on-chip first electroplating nickel or copper, made of "has electroless nickel or copper, battery anode film," and then chip in the battery anode indium or tin plating.

The use of the patented technology, the program produced mercury-free button batteries, in 2002, that had been successful in the realization of industrial production, the product of mass entering the market, is purchasing the use of well-known enterprises such as McDonald's, and received praise from environmental groups about the United States, achieved a Sony, Toshiba, Hitachi, Panasonic and other multinational efforts for many years failed to achieve the technical objectives for the protection of ecological environment of mankind has made a strong IBM 08K8199 Battery contribution.
