Document Type and Number:
WIPO Patent Application WO/2023/240797
Kind Code:
A1
Abstract:
The present application discloses a battery and an electric device. In an embodiment of the present application, the battery comprises a plurality of first battery cells and a battery unit. The battery unit and the plurality of first battery cells are stacked in a first direction. The battery unit comprises a plurality of second battery cells arranged in a second direction, and the second direction is perpendicular to the first direction. The first battery cell and the second battery cell have different shapes. In the first direction, the second battery cells at least partially overlap with the first battery cell. In the second direction, a gap is arranged between at least two adjacent second battery cells of the battery unit. The gap can provide space for expansion of the first battery cell, such that the expansion force acting upon the first battery cell is reduced, thereby improving the cycle performance of the first battery cell, and extending the service life of the battery.
