▎ 摘　　要

NOVELTY - In-situ synthesis of graphene-coated two-dimensional metal compound electrode material, comprises placing metal elemental powder in a vacuum tube furnace, calcining in a mixed atmosphere of inert gas and CX2 gas, cooling with the furnace, where the X is sulfur, selenium, and/or telerium. USE - The method for in-situ synthesis of graphene-coated two-dimensional metal compound electrode material useful for lithium ion battery (claimed). ADVANTAGE - The method has one step, is convenient, economical, and is suitable for industrial large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-coated two-dimensional metal compound electrode material, obtained by the method as mentioned above.
