  Electrolytic manganese dioxide is an excellent depolarizer for batteries. Compared with dry batteries produced by natural discharge of manganese dioxide, it has the characteristics of large discharge capacity, strong activity, small volume and long life. It is mixed with 20-30% EMD. The dry battery made by the dry battery can be increased by 50-100% than the dry battery made of natural MnO2. The high-performance zinc chloride battery can be mixed with 50-70% EMD, and the discharge capacity can be increased by 2-3 times. The alkaline manganese battery made of EMD can increase the discharge capacity by 5-7 times, so electrolytic manganese dioxide becomes a very important raw material for the battery industry.
