Abstract
Disclosed are a manganese-doped cobaltosic tetroxide, and a preparation method and application thereof, belonging to the field of battery materials. The preparation method of the manganese-doped cobaltosic tetroxide of the disclosure dopes a manganese element into cobalt carbonate with a specific process and matched with a composite surfactant, which can obtain manganese-doped cobaltosic tetroxide particle products with uniform particle size, dispersion and fineness through high-temperature sintering, a proportion of low-valence manganese in the doped manganese is high, and a crystal form of the products obtained by sintering is complete. The preparation method is simple in operation and can realize industrial large-scale production. The manganese-doped cobaltosic tetroxide prepared by the preparation method and the application thereof are also disclosed.
