Abstract

This application provides a battery, including: a casing; a cover plate, the cover plate being configured to cover the casing; and a core, the core being disposed in the casing and provided with tabs, a plurality of tabs being connected to the cover plate after convergence. A tab bending space for accommodating a bent tab is formed between the cover plate and the core. A height of the tab bending space along a first direction is greater than D/10 and less than 3D/4, and D is a thickness of the core. The battery in this application has a reasonable tab bending space design, and such a space design can not only ensure that the tab bending angle is kept within a certain range to avoid a short circuit so as to improve the safety of the battery, but also can ensure the battery core capacity.
