▎ 摘 要
NOVELTY - Preparing multi-component doped graphene sodium ion cathode material comprises mixing copper nitrate, silver nitrate and graphene oxide, then adding aqueous ammonia dropwise to prepare a mixed solution containing copper ammonia and silver ammonia, adding glucose solution and heating to prepare cathode material. USE - The method is useful for preparing multi-component doped graphene sodium ion cathode material. ADVANTAGE - The cathode material can increase electrical conductivity, and has excellent electrical and electrochemical properties. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: multi-component doped graphene sodium ion cathode material prepared by the above preparation method; and battery, comprising multi-component doped graphene sodium ion cathode material.
