Recently, the New Leader Battery Co., Ltd. overcome technical difficulties, it fill gaps for the invention of the world in the production of mercury-free buttonSony NP-FP70batteries,it has made tremendous contributions for environmental protection in China and the world .
As a battery-producing country, China’s battery (such as :Kodak KLIC-8000))industry occupied the world’s output of more than half of the battery in 1995 . However, due to the battery prior to containing excessive levels of mercury, which we usually refer to the mercury, leading to environmental pollution and poisoning, making battery life safety issues stood out.
And a high using frequency of thePanasonic CGA-DU21 battery and universality, it maks the threat of mercury-containing batteries become more prominent. It is reported that a micro-mercury alkaline button batteries contaminated water is 60 million liters of drinking water,it 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 the relevant provisions, and it clearly defined alkaline zinc-manganese batteries can not be added mercury and mercury content of no more than 0.0005% of total Kodak KLIC-7004 cells, but because the world has no technology to produce mercury-free button batteries for button cells can only allow mercury content is no more than 2% of the total mass of the battery.
In other countries, well-known battery manufacturers of mercury-free button cell mercury-free overtaken by a large number of studies more than a decade in Japan and the United States and Europe and other(take the Dell xps m1330 battery, for example) . However, because there are technical problems not to be resolved, so there is no one company which can successfully produce mercury-free alkaline button batteries, resulting in mercury-containing alkaline button batteries has been used in the global market . Button cell are producted and used 1 billion each year , so that China and the rest of the world people are still faced with the danger of mercury exposure.
The problem with the new Canon NB-2L Battery Co., Ltd Lida invention can be resolved.October 3, 2002, the new Leader for the “mercury-free alkaline button batteries” utility model patents successfully been authorized. In order to avoid patent issues encountered in overseas markets, the company again sync have applied for a number of the patent in the United States, Germany, Britain and other EU countries. However, China’s mercury-free button batteries for Dell precision m90 series battery are quite bumpy road. Over the years, as competitors have mentioned many times repeated the request is invalid, and no mercury button batteries 10-year patent protection period is about to expire, the ultimate fate of the concern of the patent.
China Battery Industry Association believed that is a “landmark” of technological progress for mercury-free button cell ,Dell precision m series battery industry to the world . U.S. Natural Resources Environment Association has also issued a letter to the China Battery Industry Association, and praised the newly developed non-Lida’s tribute make a major contribution to global environmental protection .
