BATTERY, CURRENT COLLECTOR FOR A BATTERY, BATTERY PACK AND VEHICLE INCLUDING A BATTERY PACK

A battery according to an embodiment of the present disclosure includes an electrode assembly formed by winding a first electrode, a second electrode and a separator interposed between the first electrode and the second electrode around a winding axis, wherein the first electrode includes a first uncoated region free of an active material layer, the first uncoated region being disposed adjacent to an edge of the first electrode extending along a winding direction of the electrode assembly, wherein the first uncoated region is exposed from the separator and at least a part of the first uncoated region itself is used as an electrode tab; a housing in which the electrode assembly is arranged; a first current collector including an edge portion arranged on the electrode assembly, a first uncoated region coupling portion extending inward from the edge portion towards the winding axis and coupled with the first uncoated region, and a terminal coupling portion spaced apart from the first uncoated region coupling portion; and a terminal which is coupled with the terminal coupling portion.
