▎ 摘　　要

NOVELTY - Current collector comprises fiber base layer, where the fiber sides surface respectively the base layer is provided with a first adhesive layer and a second adhesive layer. The first adhesive layer and the second adhesive layer away from the fiber surface respectively layer is provided with a first metal layer and a second metal layer. The material of the fiber layer comprises 50-120 pts. wt. composite fiber, 4.1-19 pts. wt. inorganic filler and auxiliary agent, where the composite fiber comprises organic fiber and inorganic fiber. USE - The current collector is useful in a battery e.g. a lithium ion battery, a lead-acid battery, an alkaline battery and a polymer battery. ADVANTAGE - The current collector can realize the light weight of the battery and avoid the metal layer from falling. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparation method of the current collector. Electrode pole piece. Battery monomer. Battery pack. Electric device. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the current collector. 100Fiber layer 200First bonding layer 300First metal layer 400Anti-oxidant layer 500Second bonding layer 600Second metal layer 700Second anti-oxidation layer
