▎ 摘 要
NOVELTY - Preparing graphite alkenyl sodium ion battery cathode material comprises (i) adding graphene oxide to absolute ethanol, and ultrasonically processing at a certain temperature to obtain an oxidized graphite alcohol dispersion liquid, (ii) adding cobalt nitrate and sodium nitrite to water to dissolve to obtain a solution A, (iii) adding acetic acid to the solution A and then adding hydrogen peroxide to react, (iv) separating solid and liquid to obtain solution B, and (v) adding oxidized graphite enol dispersion solution to solution B to obtain solid matter, calcining solid insulating oxygen, washing and drying. USE - The method is useful for preparing graphite alkenyl sodium ion battery cathode material. ADVANTAGE - The method provides graphite alkenyl sodium ion battery cathode material with improved specific capacity and cycle performance.
