Negative electrode plate, secondary battery, battery module, battery pack, and electric device

Abstract

A negative electrode plate, including: a current collector and a first active layer provided on a surface of the current collector, where the first active layer includes a first active material and a second active material, the specific surface area of the first active material is greater than the specific surface area of the second active material, the current collector includes a first region and a second region which are arranged in a first direction, and the first active layer corresponding to the first region includes a first active material, and the first active layer corresponding to the second region includes a second active material, the first region being a region formed by the negative electrode plate protruding from a positive electrode plate in the first direction, and the second region being a region formed by the negative electrode plate overlapping with the positive electrode plate in the first direction.
