Mercury-free button batteries to fill the gaps in environmental protection
Recently, the new leader Battery Co., Ltd. overcome technical difficulties, the invention of the world to fill gaps in the production of mercury free button batteries, the environmental protection in China and the world has made tremendous contributions.
As a farm producer, the battery industry in China in 1995, held the world production of over half of the battery. However, because of the battery prior to contain excessive levels of mercury, which we usually refer to the mercury, causing environmental pollution and poisoning, which makes security issues battery life stood out.
And because the VGP-BPS8 battery of a high frequency of use and universality, making the threat of mercury-containing batteries become more evident. It is reported that a micro-mercury alkaline button cells can be contaminated by water is 60 million liters of water is equivalent to the amount of a person’s life. Although in 1995 the United States and Europe have issued a ban on the sale of mercury-containing batteries with relevant and clearly defined, alkaline zinc-manganese batteries can not be added to the mercury content Mercury is more than 0.0005% of the total number of cells, but because the world has no technology can produce mercury free button batteries, button cells can not allow the mercury content is more than 2% of the total mass of the battery.
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. 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.
The problem with the new Battery Co., Ltd Lida invention can be resolved. After years of research and development testing, the new head of R & D team in 2000, mastered the technical formula, success will be mercury-free alkaline button cells. October 3, 2002, the new head of Mercury “without alkaline button cells” patents for utility models successfully authorized. To avoid problems patent on foreign markets, the company synchronization back to the United States, Germany, Great Britain and other EU countries have asked for a patent number. However, the mercury of China road-free button batteries are quite bumpy. Over the years, as competitors have raised repeatedly reiterated the request is invalid, and no mercury button cell VGP-BPS10A batteries 10-year period of patent protection is about to expire, the ultimate fate of the concern of the patent.
China Battery Industry Association, said the mercury key industry free cell battery, the world is a “historical” of technological progress. With this technology for the first time addressed the problem of mercury in button cells, avoiding the appearance of the tragedy of mercury poisoning, therefore protecting the global environment has made a significant contribution. U. S. Natural Resources Environment Association also issued a letter to the Industrial Association of China battery, praised the newly developed non-Lida homage to protect the global environment cause the battery to make a major contribution .
