Dry Battery Material--Electrolytic Manganese Dioxide

1.Product Introduction
Electrolytic manganese dioxide(EMD) is the excellent depolarizing agent for battery, it has the characteristics of large discharge capacity, strong activity, small volume, long service life, etc. which, therefore, makes it a very important raw material in the battery industry.
Our company supply a large number of EMD in the stable and long-term way and has a number of cooperative factories. Our cooperative factories has a rigorous quality-control in the whole manufacturing process and a discreet quality-inspection after production so as to ensure a good and satisfactory quality of productsbefore they flow into the market.2.Chemical Composition
