Abstract

A battery and an electric device are provided. The battery includes an electrode assembly, a housing, and a terminal post, where the electrode assembly is accommodated in the housing. The housing includes a first wall and a second wall disposed opposite each other along a first direction and includes a peripheral side wall surrounding the first wall and the second wall and disposed therebetween. The first direction is a thickness direction of the battery. The first wall includes a reinforcement portion, where the reinforcement portion protrudes beyond the peripheral side wall. The peripheral side wall includes a top wall and a bottom wall disposed opposite each other along a second direction, where the top wall is provided with a through-hole, and the terminal post is disposed at the through-hole. In the above battery, the reinforcement portion protrudes beyond the peripheral side wall. During battery swelling, the reinforcement portion can suppress formation of creases at an edge of the first wall, reduce pulling on the peripheral side wall, and provide support to the peripheral side wall, enhancing structural strength of the peripheral side wall, improving resistance of the peripheral side wall to tensile deformation, thereby reducing a risk of collapse of the peripheral side wall and improving safety performance of the battery.
