▎ 摘　　要

NOVELTY - Flexible composite current collector comprises metal grid substrates and composite materials coated on both surfaces of the metal grid substrate and fills the grid holes, where the composite material comprises a high molecular polymer and a conductive agent. USE - Flexible composite current collector for a battery i.e. lithium ion battery. ADVANTAGE - The current collector improves the flexibility of the current collector, improves the use performance of the collector, and prolongs the shelf life of the battery, and has excellent conductive network. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a pole piece; (2) a battery; (3) a preparation method of flexible composite current collector.
