Abstract

A battery is provided in the present disclosure. The battery includes: a positive electrode plate including a positive current collector and a positive active material layer; a negative electrode plate including a positive current collector and a negative active material layer; and an electrolyte. The positive current collector includes an insulation layer used to support a conductive layer and the conductive layer used to support the positive active material layer and located above at least one surface of the insulation layer. The conductive layer has a thickness of D2 which satisfies: 300 nm≤D2≤2 μm. A protective layer is arranged on at least one surface of the conductive layer. The negative current collector is a copper foil current collector having a thickness of 1 μm to 5.9 μm.
