China’s first leader in the world: mercury-free button batteries
In June 2009, a new attracted our attention: Sony Corporation has announced the six models of mercury-free alkaline button batteries (LR) of the marketing plan, laptop battery rechargeable which means that the Sony-mercury button batteries are fully free market.
In fact, as early as eight years ago, China’s New Leader Battery Co., Ltd. Business battery had been a breakthrough ahead of other countries that have plagued the world’s problems, and was the first conducted a large-scale production.
The mercury batteries inside a great harm to humanity, because the battery inside the mercury on the brain and nervous system toxin interfere significantly with normal nerves, the exposure fetus or infant to high doses of mercury can cause mental retardation, cerebral palsy, hearing impairment or loss of vision and so on. Even exposure to low doses of mercury, may also affect the healthy development of children, it may enable them to attract attention, dell fk890 battery,dell gk479 battery action coordination, language skills, visuospatial, and memory problems text. For adults, a chronic mercury poisoning can cause memory decline, seizures, vision loss, and the hands, feet means paralysis, and fertility and the devastating effects of blood pressure. Increasing evidence shows that exposure to mercury may increase heart disease.
And because the battery of a high frequency of use and universality, making the threat of mercury-containing batteries become more evident. It is reported that a New Zealand-style micro-mercury alkaline batteries can be contaminated by water is 600,000 liters, equivalent to the amount of water, the life of a person.
In other countries, more than a decade in Japan and the United States, Europe and other well known manufacturers of mercury-free batteries, mercury free button cell surprised 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 cell, resulting in the global market has been the use of mercury-containing button cell alkaline. sony vgp-bps9 battery Coin 1 billion each year by the production and use, so that China and the rest of the world, people still face the risk of mercury exposure.
While all research stopped, when this problem by breaking the new company-Qing Li Dade. In this regard, the China Battery Industry Association and the American groups of the environment have given a high degree of recognition and evaluation as the cause of the world’s great contribution to protecting the environment. With the invention of this technology, China has become the world’s first mercury in battery-free buttons cracking problems of the country.
It is understood that the reasons for mercury button batteries, mercury is used to block cream zinc anode of the battery with pieces of metal anode contact, because these contacts produce hydrogen gas, leading to cell swelling deformation, leak or even explosion. Early mercury button cell battery problem leak also exists, which affects performance, battery life and use of the most fatal flaw, but in the late 70s of last century, mercury leakage problems of button cells, they were forwarded to the original use of punch made with stainless steel plate and then nickel plated or gold, “the negative coverage, toshiba pa3399u-1brs battery replaced by a” nickel, stainless steel, copper laminated composite formed the “Group of metal composite,” made negative coverage, and other improvements related to actually be controlled.
The purpose of this patented invention, is to maintain the original mercury (eg mercury) batteries buttons fight against the performance of the leak itself based on mercury free button batteries.
The patent on October 19, 2001 by the National Office of Intellectual Property in the patent application, and October 2, 2002 announcement was authorized by the patent No. 01234722.1.
With the use of mercury-containing button cell and the increasing volume of waste, waste batteries, mercury pollution of the environment is becoming more serious. Thus, the needs of environmental protection, button cell battery industry manufacturing has been eager to set the battery in the mercury problem. In this patent application, Sony, Toshiba, Hitachi, Panasonic, Seiko, etc. at the button battery R & D and manufacturing industry, the leading position among Japanese companies, are mercury free button batteries for solve the problem for a variety of attempts and efforts to put forward all kinds of technological solutions. All these technical programs are committed to addressing mercury free leakage caused by the new problem, but failed to respond effectively to mercury free technology and anti-leakage effect of the two. apple a1245 battery Therefore, this patent application until a few days ago, button battery manufacturing may actually have not effectively address both mercury-free technology and the fight against the problem of leakage, and therefore mercury free button batteries are not even really realize the industrialization and market access.
This patent search and development through the use of unconventional ideas, successfully resolved the distress button industry of the manufacture of batteries for many years of technical problems. Before the date of this patent application, all addressing the issue of mercury-free technology for improving the program are in the existing technology base to mitigate the negative effects of escalation (eg, leaks) Speed commonly used by nickel - stainless steel - made from copper to remove three layers composite plate consisting of the CAP metal anodes based on a sophisticated system, all designed to improve the programs do not address the negative laminate cover any changes in the structure itself Similarly, even knowing that negative coverage multilayer structure forming the dislocation occurs and damage and coatings used in its suppression of the hydrogen produced by indium or tin, causing the battery chamber of the tire and leakage is still a proposed complex of many other “plugs” of the program, but has not given regarding the availability covered by changing the negative multilayer structure to solve this problem, inspiring art.
And this patent is another way, dell xps m140 battery its R & D and put aside the idea of super-normal manner by existing technology, made of three layers of sheet metal composite anode covered with a laminate structure, but directly by the metal plates and sheets stainless steel anode on-chip gold, silver, copper, tin, indium and other tests and found that the negative on the chip or indium tin -plated success in controlling cream zinc anode of the battery in contact with the film anode product gas as well as the improvement of raw materials and formulations on the successful production of a mercury-zinc free alkaline-manganese, zinc / silver manganese button-type batteries. based on the discovery, the completion of the present utility model. ”
In this patent, the technical program to better the negative on the chip or indium tin plating and the elimination of a single pinhole surface prone to problems presented in this patent by plates of iron or stainless steel in negative film on the bare chip first nickel plating or copper, because of “a chemical nickel or copper, anode film battery,” and then in the chip of indium anode battery or tinning.
Using patented technology, the program has produced mercury free button batteries in 2002, which had been successful in achieving industrial production, the product of the mass market, buys the use of ‘well-known companies such as McDonald’s, and has received praise from environmental groups in the United States, reached a Sony, sony vgp-bps10/s battery , sony vgp-bps13 battery Toshiba, Hitachi, Panasonic and other multinational efforts for many years failed to achieve the technical objectives for protecting the ecological environment of mankind has made a significant contribution.
