▎ 摘　　要

NOVELTY - Lithium ion battery current collector comprises a porous current collector base body and a conductive adhesive layer arranged on the surface of the base body of the porous cathode collector. USE - The lithium ion battery current collector is useful for preparing lithium ion battery (claimed). ADVANTAGE - The current collector: prevents active material from falling to improve the cycle stability of the battery, enhances bonding force between the active materials and the pole piece; and improves battery energy density. The conductive adhesive layer has the adhesive effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing lithium ion battery current collector; and (2) lithium ion battery.
