(57) Abstract: Provided is a battery pack (10), comprising multiple battery cells (100) overlapping with each other. The battery packfurther comprises an electrode tab connection apparatus. The electrode tab connection apparatus comprises a base (202), a coverbody (204), a conductive connection pole (206) and an electrode tab shim (208). The electrode tab shim is arranged between thebase and the cover body, and the electrode tab shim is provided with rounded corners. Electrode tabs of at least two battery cells aresmoothly bent along the corners of the electrode tab shim, and overlap each other between the electrode tab shim and the cover bodyto implement electric contact. Overlapping parts of the electrode tabs of the at least two battery cells are provided with first throughholes (212) communicating with each other. The conductive connection pole passes through the first through holes. Also provided isthe electrode tab connection apparatus.
