Publication number: 20250038363Abstract: The application discloses a battery cell, a battery, and an electrical device. The battery cell includes a shell, an electrode assembly and a buffering member. The shell includes two first side walls opposite to each other in a first direction, with a spacing of D1 between the two first side walls in the first direction. M electrode assemblies and N buffering members are accommodated inside the shell, where M and N are a positive integer greater than 0. In the fully charged state, the sum of the dimensions of M electrode assemblies along the first direction is D2. N buffering members and M electrode assemblies are stacked in the first direction. The buffering member is configured to be compressible, and the sum of the dimensions of N buffering members along the first direction in an uncompressed state is D3. D1, D2, and D3 meet: 0.9?(D2+D3)/D1?1.5.Type: ApplicationFiled: October 10, 2024Publication date: January 30, 2025Inventors: Tao Zhang, Jianfu He, Qian Liu, Chen Cui, Xueyang Sun, Yonghuang Ye
