1. A tab limiting sheet, configured to be insulated and disposed between a cell body and two tab bodies of a battery cell, wherein the two tab bodies are arranged at intervals along a first direction, and the tab limiting sheet further comprises:
a first mounting part and a second mounting part respectively configured to abut against the two tab bodies tightly; and
a connecting assembly, wherein the first mounting part, the connecting assembly, and the second mounting part are sequentially connected along the first direction, and the connecting assembly comprises:
an elastic element, wherein both ends of the elastic element are respectively connected with the first mounting part and the second mounting part; and
a first support element comprising a first supporting part connected with the first mounting part and a second part connected with the second mounting part;
wherein when the elastic element is in a natural state, the first supporting part and the second supporting part are spaced in the first direction, and when the elastic element is squeezed to a maximum deformation state, the first supporting part is tightly abutted against the second supporting part.
