Anti-extrusion battery cell shell and battery pack

The utility model relates to the technical field of batteries, in particular to an anti-extrusion battery cell shell and a battery pack. The anti-extrusion battery cell shell comprises a shell body, the anti-extrusion structure is arranged at the relatively lower position of the shell body in the height direction, and the anti-extrusion structure is suitable for supporting the shell body and is suitable for deforming before the shell body when the anti-extrusion battery cell shell is extruded. According to the anti-extrusion battery cell shell provided by the utility model, the anti-extrusion structure is arranged at the relatively lower position of the shell body along the height direction, so that the anti-extrusion battery cell shell is suitable for being deformed before the shell body is extruded, and the anti-extrusion capability of the shell body is improved; the battery core shell is prevented from being directly extruded to the pole group pole pieces in the battery core after being extruded, and the p
