ACMD

ACMD (For Zn-Mn dry cells use only) Activited Chemical Manganese Dioxide (ACMD) is a kind of cathode material which has the similar discharge performance to EMD and price is definitly cheaper USD250 than that of EMD. This product has the advantages such as large specific surface area, good absorption and high discharge activity and has been widely used in high power and high capacity Zinc-Manganese batteries owing to its excellent heavy-duty continuous discharge property. Over 90% battery manufacturers in China have adopted this product to reduce their manufacturing cost and enhance their competition among the same industry. In addition, there are also many famous international enterprises using this product, such as Toshiba Battery Co.,Ltd in Japan, Matsushita Group ( shanghai Panasonic, India Panasonic, Japan Panasonic, ect), Chung Pak Battery Co.,Ltd in Hong Kong, Gold Peak Battery Co.,Ltd inHong Kong and Hi-Watt Battery Co.,Ltd in Hong Kong and so on.
