Abstract
A positive electrode sheet and a battery cell comprising the positive electrode sheet, a battery, and an electric device. The positive electrode sheet comprises a composite current collector and a positive electrode film layer provided on at least one surface of the composite current collector. The composite current collector comprises a polymer material base layer and a metal composite layer located on at least one surface of the polymer material base layer, and the active material of the positive electrode film layer comprises the Ni element. The metal composite layer comprises a metal matrix layer and a metal oxide layer which are stacked. The resistivity of the metal oxide layer is greater than that of the metal matrix layer. The positive electrode sheet can effectively alleviate DCR deterioration and reduce battery failure.
