Document Type and Number:
WIPO Patent Application WO/2020/215927
Kind Code:
A1
Abstract:
The embodiments of the present application relate to a battery. The battery comprises an arc-shaped metal shell, an arc-shaped metal plate and an arc-shaped electrode assembly. The arc-shaped metal shell has an arc-shaped surface and a plurality of sidewalls extending from the arc-shaped surface. The arc-shaped electrode assembly is provided between the arc-shaped metal shell and the arc-shaped metal plate. The plurality of sidewalls engage with the arc-shaped metal plate so as to seal the arc-shaped electrode assembly between the arc-shaped metal shell and the arc-shaped metal plate. By arranging an opening direction of the arc-shaped metal shell, the present application greatly reduces the difficulty in the manufacturing process of a battery, so that the placement of arc-shaped electrode assemblies having different structural forms into the arc-shaped metal shell is convenient and smooth, further improving the energy density of the battery.
