Abstract: A shell includes an insulating layer provided at an outer surface of the shell and including a repair part formed of a curable material and having a shape of a mushroom. The repair part includes an upper part having a shape of a cover of the mushroom and a lower part having a shape of a stem of the mushroom. The lower part is embedded in the insulating layer, the upper part protrudes from the insulating layer, and a lower surface of the upper part covers at least a portion of an upper surface of the insulating layer. In a cross section of the repair part perpendicular to a surface of the insulating layer, a longest dimension of the upper part is greater than or equal to a sum of a width of the lower part and a creepage distance of a battery.

Abstract: This application provides a battery and an electric device. The battery provided in this application is provided with a blocking member between two adjacent rows of battery cells along the length direction of the battery cell. In the process of assembling the battery cells in the box, the adhesive at the bottom of the battery cell, when spreading under compressing from the gap created by the housing chamfers to the end cover, will be blocked by the blocking member, thus preventing the adhesive from overflowing to the end cover, improving the safety performance of the battery.
