The magnesium-water battery jointly developed by Jiangsu Zhongke Yamei New Materials Co., Ltd. and Jiaxing Light Alloy Technology Engineering Center of the Chinese Academy of Sciences fully utilizes the lightness of magnesium alloy as the negative electrode of the battery in design, which effectively improves the capacity of the single battery , more than 1.5 times that of carbon batteries. The unique water-added battery design and magnesium-air battery design make it have a long-term storage capacity. As an emergency reserve battery, it has great advantages such as high capacity, long storage time, and convenient use. At present, the disposable magnesium water batteries developed have been gradually introduced to the market. The production of No. 1 and No. 5 magnesium water batteries has already formed a scale, while emergency LED power supplies, outdoor lantern flashlights, reserve batteries and power banks are developed for magnesium water batteries. Products will also be put on the market one after another. In the future, it will form new products in the fields of magnesium alloy profiles, surface protection, magnesium batteries, etc., expand the market, and build a comprehensive and sustainable high-tech company in the field of magnesium alloy application technology products.
