▎ 摘  要

NOVELTY - Dispersion system anode lithium supplement additive formed by dissolving lithium- supplementing compounds, polymers and conductive agents in organic solvents to form a coating structure. The lithium-supplementing compound is located in the inner core, the polymer is coated outside the inner core, and the conductive agent is coated outside the polymer. USE - The dispersion system anode lithium supplement additive is useful in lithium ion battery. ADVANTAGE - The system has certain viscosity, enhances the conductivity and environmental stability of the lithium compound, and inhibits the negative influence of the decomposition product, and realizes efficient lithium supplementation while improving the first coulombic efficiency and cyclic stability of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: use of dispersion system anode lithium supplement additive. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the dispersion system anode lithium supplement additive is useful in lithium-ion battery. (Drawing includes non-English language text).
