Document Type and Number:
WIPO Patent Application WO/2024/055312
Kind Code:
A1
Abstract:
The present application relates to the field of batteries, and provides a battery cell, a battery, and an electric device. The battery cell comprises a housing, an electrode assembly, an end cover assembly, and a supporting member. The housing is provided with an opening. The electrode assembly is provided with a main body portion and a tab protruding out of the main body portion, and the electrode assembly is accommodated in the housing. The end cover assembly covers the opening. The supporting member is located in the housing, and the tab is bent around the supporting member. The supporting member is connected to the end cover assembly to fix the supporting member. The supporting member is arranged in the battery cell, the tab is bent around the supporting member, and in the scene of inverting the battery cell, the supporting member can support the main body portion, so that the gravity of the main body portion is not easily transmitted to the tab, and tab bifurcation and insertion are not prone to being caused, thereby improving the safety of the battery cell. In addition, the supporting member is connected to the end cover assembly, so that the supporting member cannot move up and down in the housing, and the tab bent around the supporting member cannot be driven to move, thereby facilitating keeping the form of the tab, and preventing the tab from being damaged when being driven.
