Title:
SEPARATOR, BATTERY, AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/041234
Kind Code:
A1
Abstract:
A separator, a battery and an electrical device. The separator comprises a bearing part and a functional part which are connected to each other. The bearing part is used for supporting two adjacent groups of battery cells and being connected to the battery cells, and the functional part is used for providing an expansion space for the two adjacent groups of battery cells in a thickness direction of the separator. When the separators are arranged in the battery casing, each separator can be supported between two adjacent groups of battery cells by the bearing part, and an expansion space is provided for every two adjacent groups of battery cells in the thickness direction by means of the functional parts. Therefore, the separator can enable the battery cells to form a group structure, the battery cells can be directly contained in the battery casing by means of the separator, and the battery cells can work normally in the battery casing, thereby simplifying the overall structure of the battery, improving the space utilization in the battery, and thus increasing the energy density of the battery.
