Secondary battery and electronic apparatus

Abstract

A secondary battery including a housing and an electrode assembly, where the housing accommodates the electrode assembly and the electrode assembly is configured to be curved in a first direction. The electrode assembly includes a cathode electrode plate, a separator, and an anode electrode plate arranged in a stacked manner, where the separator includes a first surface and a second surface oppositely disposed along the first direction. The separator includes a first adhesive layer disposed on the first surface and a second adhesive layer disposed on the second surface, the first adhesive layer adhering to the anode electrode plate and the second adhesive layer adhering to the cathode electrode plate. A peel strength between the first adhesive layer and the anode electrode plate is S1 and a peel strength between the second adhesive layer and the cathode electrode plate is S2, satisfying S1<S2.
