▎ 摘 要
NOVELTY - Method for preparing spherical manganese dioxide, involves (a) placing water-sulfate in an organic solvent at room temperature to dissolve, (b) dissolving bicarbonate, aluminum powder and modified graphene in the organic solvent, and (c) placing the manganese dioxide fine particles, filtering and removing water, placing in a blower, heating and drying, cooling, (d) introducing in a mortar and grinding with acetone, (e) placing in the muffle furnace for calcining, grinding into powder and (f) sieving to obtain the spherical man-made man-machine dioxide. USE - The method is useful for preparing spherical manganese dioxide by using computer device. ADVANTAGE - The method is simple, low energy consumption, and cost effective. The prepared spherical manganese dioxide impurity is little, electrochemical charging and discharging performance is excellent, and has wide popularization and application meaning. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a computer device; (2) a computer-readable storage medium comprising a set of instructions for method for preparing spherical manganese dioxide; and (3) an information data processing terminal. DESCRIPTION OF DRAWING(S) - The drawing shows a preparation method flow chart of quasi-spherical manganese dioxide.
