▎ 摘　　要

NOVELTY - A manganese alkoxide and graphene composite is prepared by adding potassium permanganate and graphite oxide into organic alcohol, and carrying out ultrasonic treatment to obtain an alcoholic liquid of potassium permanganate and graphite oxide. The obtained liquid is heated in an oil bath pan, and ethylene diamine is added into the liquid. The resulting liquid is heated and a constant-temperature reaction is carried out to obtain precipitation of reactants. The obtained precipitate is centrifugally cleaned and dried to obtain powder. USE - Manganese alkoxide and graphene composite for use in a lithium ion battery cathode (claimed). ADVANTAGE - The composite is prepared in a simple manner with high repeatability, and provides good cathode material performances of the lithium ion battery. DETAILED DESCRIPTION - A manganese alkoxide and graphene composite is prepared by adding potassium permanganate and graphite oxide into organic alcohol, and carrying out ultrasonic treatment to obtain an alcoholic liquid of potassium permanganate and graphite oxide. The obtained liquid is heated in an oil bath pan, and ethylene diamine is added into the liquid. The resulting liquid is heated and a constant-temperature reaction is carried out to obtain precipitation of reactants. The obtained precipitate is centrifugally cleaned and dried to obtain powder, where the manganese alkoxide is a nanosheet structure or a compound structure of a nanosheet and a graphene sheet, and the size of the sheet structure of the manganese alkoxide is 300 nm-3 mu m. An INDEPENDENT CLAIM is also included for a method for preparing a manganese alkoxide and graphene composite.
