▎ 摘　　要

NOVELTY - Two-dimensional material modified lithium battery cathode current collector surface coating, is formed by coating surface of cathode current collector with conductive paste. The conductive paste comprises 57-88 pts. wt. water, 5-12 pts. wt. conductive carbon material, 1-5 pts. wt. black phosphorus, 5-25 pts. wt. hyperdispersant and 0.1-1 pts. wt. pH regulator. The conductive carbon material in the coating is combined with two-dimensional sheet-like black phosphorus through carbon-phosphorus bond. The black phosphorus has a two-dimensional wrinkled pore structure. USE - The coating is useful in cathode electrode of lithium battery (all claimed). ADVANTAGE - The coating provides a strong adhesive force, high conductivity and good mechanical cathode of the surface coating, has stronger structure, the two-dimensional fold channel structure and conductive material with small size form stable combination, the penetration of the sheet layer makes the wetting property of the coating surface better, and the bonding force with cathode material is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: preparing two-dimensional material modified lithium battery cathode current collector surface coating; cathode electrode; and lithium battery. DESCRIPTION OF DRAWING(S) - The drawing shows a two-dimensional material modified lithium battery positive electrode the invention the present invention preparation method flow chart of the surface coating.
