Manganese hypophosphite contains one molecule of water of crystallization and possesses certain reducing properties, making it widely used in polymer catalysts, chemical synthesis reduction, food additives, and pharmaceutical precursors. When used in lithium-ion battery anode or cathode materials, it can optimize interface stability, reduce side reactions, improve cycle life and energy density, lower self-discharge rate, and improve rate performance and thermal stability. Adding manganese hypophosphite to electroplating solutions can increase deposition rate, refine grain size, and improve coating uniformity and corrosion resistance. In ceramics, it can enhance thermal and chemical stability; in semiconductor materials, doping can improve conductivity and corrosion resistance; and it is used in the production of matte fibers to adjust their appearance.

Manganese hypophosphite is an inorganic compound whose mechanism of action is mainly based on the reducing power of hypophosphite and the catalytic or functional effects of manganese ions. Hypophosphite is oxidized on catalytic surfaces such as palladium and nickel to generate phosphite, while releasing electrons to reduce nickel ions in solution to metallic nickel. Mn²⁺ is co-deposited with nickel to form a nickel-manganese-phosphorus alloy coating, which enhances the coating's hardness, corrosion resistance, or magnetism.
