▎ 摘　　要

NOVELTY - A positive electrode containing lithium supplement composition comprises current collector, a lithium-supplementing composition layer and a positive electrode active material layer arranged on at least one side of the current collector. The lithium-supplementing composition layer comprises a lithium-supplementing agent, a binder (A), a conductive agent (A) and a lithium-ion conductor. USE - Positive electrode containing lithium supplement composition used in lithium-ion battery (claimed). ADVANTAGE - The composition adds lithium-ion conductor to lithium supplementing composition layer, which can provide a suitable migration path for migration of lithium ions in the positive electrode active material, reduce the lithium-ion migration resistance of electrode, and alleviate the polarization of battery, and improving the charging and discharging of the battery cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of positive electrode containing lithium supplement composition, which involves using organic solvent (A) and organic solvent (B).
