(Summary description)A few days ago, Xinlida Battery Co., Ltd. overcame the technical difficulties and invented the production of mercury-free button batteries that filled the world's gaps, and made great contributions to the environmental protection cause of China and the world.
    As a large battery production country, China's battery industry has accounted for more than half of the world's battery production in 1995. However, because the previous battery contained excessive mercury, which is commonly referred to as mercury, it caused environmental pollution and poisoning, making the battery safety issue more prominent.

    Due to the high frequency and universality of the battery, the threat of mercury-containing batteries is more prominent. It is reported that a miniature mercury-containing alkaline button battery can pollute 600,000 liters of water, which is equivalent to a person's drinking water in a lifetime. Although starting in 1995, the United States and Europe have successively issued relevant regulations banning the sale of mercury-containing batteries, which clearly stipulate that alkaline zinc-manganese batteries cannot add mercury, and the mercury content must not exceed 0.0005% of the total battery. Technology can produce mercury-free button batteries, which can only allow the mercury content of button batteries to not exceed 2% of the total battery mass.

    Abroad, more than ten years, Japan, the United States, Europe and other well-known battery manufacturers have done a lot of research on mercury-free button batteries without mercury. However, there are still technical problems that cannot be solved, and no company has been able to successfully produce alkaline mercury-free button batteries, which has caused the use of mercury-containing alkaline button batteries in the global market. Billions of button batteries are produced and used every year, leaving people in China and the rest of the world at risk of exposure to mercury.

    This problem was solved with the invention of Xin Lida Battery Co., Ltd. After years of research and development tests, the company's R & D team mastered the relevant technical formula in 2000 and successfully turned the alkaline button battery into a mercury-free one. On October 3, 2002, the utility model patent of "Mercury-free Alkaline Battery" applied by Xin Lida was successfully granted. In order to avoid encountering patent problems in overseas markets, the company has simultaneously applied for this patent in many EU countries such as the United States, Germany, and the United Kingdom. However, China's button-free battery road is quite bumpy. Over the years, the competitor's repeated repeated invalidation requests, and the mercury-free button battery's 10-year patent protection period is about to expire, the final fate of the patent has attracted attention.

    China Battery Industry Association believes that the realization of mercury-free button batteries is an "epoch-making" technological progress for the world's battery industry. Because this technology overcomes the problem of mercury in button batteries for the first time and avoids the tragedy of mercury poisoning, it has made a significant contribution to environmental protection worldwide. The American Natural Resources and Environment Association also sent a letter to the China Battery Industry Association praising the significant contribution made by Xinlida's non-gong battery to the global environmental protection cause.
