Positive electrode current collector for improving weight impact resistance of battery, battery cell and power utilization device

The utility model belongs to the technical field of battery production and manufacturing, and particularly relates to an anode current collector, a battery cell and an electric device for improving the weight impact resistance of a battery. The positive current collector comprises an aluminum foil base material, a first aluminum alloy coating arranged on the first surface of the aluminum foil base material, and a second aluminum alloy coating arranged on the second surface of the aluminum foil base material. By optimizing the structure of the positive electrode current collector, the overall hardness, tensile strength and ductility of the current collector are effectively improved, the weight impact test passing rate of the single battery cell is improved, the rigidity of the single battery cell is not required to be increased by using assemblies such as an over-thick diaphragm, the energy density of the battery cell is considered, and the quality of the battery is improved. 本实用新型属于电池生产制造的技术领域，具体涉及用于改善电池抗重物冲击
