Description
Discharge Manganese Powder has excellent depolarization properties, making it suitable for use in dry cell batteries (zinc-carbon batteries). Discharge Manganese Powder typically requires a manganese dioxide content greater than 50%, low iron content, and extremely low levels of heavy metals such as nickel, copper, and cobalt. It also requires a discharge time exceeding 300 minutes. Furthermore, this product contains highly electrochemically active mineral elements and possesses an ideal particle size distribution, resulting in a high specific surface area and further enhancing its advantages. We offer Discharge Manganese Powder with various content levels, providing customers with more flexible and efficient manganese dioxide selection options. It is directly mined from pyrolusite, resulting in production costs significantly lower than electrolytic manganese dioxide.
