* Manganese Dioxide waye nipa ti ara bi nkan ti o wa ni erupe ile pyrolusite, eyiti o jẹ orisun ti manganese ati gbogbo awọn agbo ogun rẹ; Ti a lo lati ṣe irin manganese bi oxidizer.
*MnO2 jẹ akọkọ ti a lo gẹgẹbi apakan ti awọn batiri sẹẹli gbigbe: awọn batiri ipilẹ ati ohun ti a pe ni Leclanché cell, tabi awọn batiri zinc–erogba. Dioxide manganese ti lo ni aṣeyọri bi ilamẹjọ ati ohun elo batiri lọpọlọpọ.
