▎ 摘　　要

NOVELTY - The composite material has a Mxene material, graphene and a metal. The Mxene material is in a lamellar structure. The graphene and the metal are located between the lamellar structures of the Mxene material. The metal comprises sodium (preferred), lithium or potassium. USE - Composite material for electrode, battery and electronic device (all claimed). ADVANTAGE - The graphene in the composite material is used for improving the conductivity and the rate capability of the electrode. The Mxene material has a large specific surface area due to the fact that the Mxene material has a multi-layer sheet structure. The Mxene material is used for increasing the position of ion deposition in the electrode. THe ion uniform deposition is facilitated, generation of ion dendrites is effectively inhibited, the use stability of the electrode is improved, and repeated cycle use of the electrode is facilitated. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of making the composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a method for manufacturing the composite material. (Drawing includes non-English language text).
