Abstract: A pressure relief component, a battery cell, a battery, and an electric device. The pressure relief component is used for a battery cell; the pressure relief component is provided with at least two pressure relief notches, each pressure relief notch and connecting lines at the two ends of said notch enclosingly form a first region, the plurality of first regions are arranged at intervals, and a connecting line of at least one first region is located on the side of the first region near the center of the pressure relief component.

Abstract: A battery cell includes a housing, an electrode assembly, and an electrode terminal. The electrode assembly is accommodated in the housing. The electrode terminal is riveted on a wall portion, and the electrode terminal is electrically connected to the electrode assembly. The electrode terminal includes a flanged portion; the flanged portion is formed at an end of the electrode terminal close to the electrode assembly and located on a side of the wall portion facing the electrode assembly; a continuous connection surface is formed at an end of the electrode terminal facing away from the electrode assembly, and the connection surface is used for connecting to a busbar component. The electrode terminal is a structure riveted onto the wall portion from inside the housing, to enable the busbar component to directly connect to the continuous connection surface at the end of the electrode terminal.

Abstract: A battery cell includes an electrode assembly and an insulating member. The insulating member includes a first insulating portion and a second insulating portion connected to each other. The first insulating portion covers a first end face of the electrode assembly, and the second insulating portion covers an outer peripheral face of the electrode assembly. The first insulating portion has a first surface facing away from the first end face and a second surface facing the first end face. The first surface and/or the second surface is provided with a protrusion, thereby improving the gravimetric energy density of the battery.

Abstract: Provided are a battery cell, a battery, and a power-consuming device. The battery cell includes a housing, an electrode assembly, and an insulator. The electrode assembly is accommodated within the housing and is formed by winding and/or stacking electrode plates. The electrode assembly has a first end surface, and the insulator is at least partially disposed between the first end surface and the housing. A portion of the insulator opposite the first end surface is provided with at least one first through hole, where the first through hole is strip-shaped. A length direction of the first through hole is parallel to or inclined relative to a stacking direction of electrode plates exposed by the first through hole. According to the technical solutions of the present application, battery yield can be improved, thereby reducing production costs.

Abstract: A battery cell includes a shell, an electrode assembly, an end cover assembly, a support member, and a terminal assembly; the shell has an opening; the electrode assembly is accommodated in the shell; the end cover assembly is closed to the opening; the support member is disposed between the end cover assembly and a main body of the electrode assembly; at least a portion of the terminal assembly extends between the end cover assembly and the support member, and the terminal assembly is conductively connected to a tab of the electrode assembly; a first accommodating portion is disposed on a first surface, facing the end cover assembly, of the support member, and the first accommodating portion is configured to accommodate at least a portion of the terminal assembly.
