BATTERY AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/226199
Kind Code:
A1
Abstract:
The present application relates to a battery and an electrical device. The battery comprises: a plurality of battery cells, wherein the large surface of each of the battery cells facing an adjacent battery cell is provided with a non-squeezable region; and a buffer structure arranged between two adjacent battery cells and used for blocking the two non-squeezable regions of the two adjacent battery cells facing each other. According to the battery, a buffer structure is arranged between two adjacent battery cells, and the buffer structure is used for blocking the two non-squeezable regions of the two battery cells facing each other, in order to prevent the two non-squeezable regions of the two adjacent battery cells from being in direct contact, thereby avoiding stress concentration caused by squeezing when the non-squeezable regions expand outwards, and avoiding lithium precipitation, so that the safety performance of the battery is improved.
