▎ 摘  要

NOVELTY - Current collector has at least one carrier layer (2) connected with at least one metal framework layer (1). The metal framework layer is provided with multiple hollow holes (10). The metal framework layer is provided with a conductive metal material. The carrier layer is provided with multiple holes (20). The forming material of the carrier layer is provided with a non-metal material. USE - Current collector used for electrode sheet of lithium ion battery (all claimed). ADVANTAGE - The collector combines the metal framework layer and carrier layer of non-metal material to form the current collector, thus reducing the weight of the metal carrier fluid, and hence improving battery quality energy density. The metal framework layer is located at the outer side of the carrier layer, thus ensuring good conductivity, and hence reducing the resistance of the current collector. The collector reduces heat productivity of the current collector and electrode, thus ensuring battery to charge and discharge large current. The collector reduces whole weight and heat productivity of the electrode sheet, and improves service life of the electrode sheet and lithium ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for electrode sheet, which has an anode sheet and a cathode sheet, where the anode sheet and cathode sheet are provided with current collector. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the current collector. Metal framework layer (1) Carrier layer (2) Multiple hollow holes (10) Multiple holes (20)
