▎ 摘　　要

NOVELTY - The light battery current collector comprises porous conductive framework and auxiliary conductive object. The auxiliary conductive object is filled in porous conductive framework of all or part of hole and surface. The porous conductive framework is stainless steel net or carbon material net. The auxiliary conductive material is graphite, expanded graphite, conductive carbon fiber, carbon nano tube, graphene, and/or conductive carbon black. USE - Light battery current collector for battery i.e. lithium ion battery, of electric automobile and energy storage. Can also be used for alkaline battery. ADVANTAGE - The light battery current collector has excellent conductivity, high strength and excellent corrosion resistance, and has light weight. The anode adopts micro-acid zinc/manganese dioxide battery of light current collector of battery having excellent charge and discharge cycle performance. The stainless steel net with same thickness is lighter than stainless steel foil, and carbon fiber material also has high tensile strength and good conductivity. The porous conductive frame and auxiliary conductive object are pressed into film as current collector, such that composite current collector ensures excellent conductive and strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation method of light battery current collector; (2) battery based on light battery current collector.
