We supply high quality dry battery grade electrolytic manganese dioxide.
Electrolytic manganese dioxide functions &performance:
Electrolytic manganese dioxide is the good depolarizator of battery, compared with the dry batteries made of natural discharged manganese dioxide, it has the features of greatly discharged capacity, great activity, small solidity, long life-span and so on .When mixed with 20%-30% EMD, the battery can discharge more 50%-100% than that made of natural MnO2 ; mixed with 50%-70% EMD, high performance Zinc chloride battery’s discharged capacity will increase 2-3 times; produced with EMD completely, alkaline manganese battery’s discharged capacity will increase 5-7times.Therefore,EMD is one of the most important raw materials in battery field.
