A battery cell includes a housing, an electrode assembly, and an insulator. The housing has a mounting cavity; the electrode assembly is disposed in the mounting cavity; the insulator includes a buffer body and an insulating body that are disposed in the mounting cavity, the insulating body enveloping the electrode assembly, and the buffer body being located between the electrode assembly and the housing; and the buffer body and the insulating body are connected to form an integral structure. This integral structure can be directly assembled with the electrode assembly to achieve envelopment of the electrode assembly, which eliminates the step of separately assembling the buffer body, reduces the number of assembly steps and the number of assembled components, and facilitates the improvement of assembly efficiency of the battery cell.
