Abstract

This application relates to a secondary battery and an electronic device. The secondary battery includes a housing, a pole, and a sealing assembly. The pole includes a first portion, a second portion, and a third portion. The first portion is disposed within the housing. One end of the second portion is connected to the first portion, and another end thereof extends out of the housing through a first through hole of the housing. The third portion is connected to the second portion outside the housing. The pole further includes a first recess. An opening of the first recess is located on a surface of the third portion facing away from the second portion. An outer surface of the second portion is provided with a first concave-convex structure. The sealing assembly includes a first sealing ring, a second sealing ring, and a third sealing ring, where the first sealing ring of the sealing assembly is disposed between a first wall surface of the housing and the first portion, the second sealing ring surrounds the second portion, and the third sealing ring is disposed between a second wall surface and the third portion. The secondary battery and the electronic device provided by this application may address the technical issue of poor sealing performance due to insufficient strength and high possibility of deformation of the pole of the secondary battery.
