Manganese dioxide

Manganese dioxide (MnO₂) is a dark, crumbly mineral commonly used in dry cell batteries, like alkaline batteries, to help generate electricity. It acts as an oxidizing agent, facilitating chemical reactions that produce electric current. Manganese dioxide is also used in water purification, as a catalyst in chemical reactions, and in the production of ceramics and glass. Its stability and ability to easily release oxygen make it valuable in various industrial processes. Overall, manganese dioxide is a versatile mineral essential in energy storage, manufacturing, and environmental applications.
