Abstract

An electrode plate for a lithium battery includes a composite current collector, a first active material layer, and a first electrode tab. The composite current collector includes a polymer layer and first metallic layer thereon. The first active material layer is disposed on a surface of the first metallic layer facing away from the polymer layer. The first active material layer defines a first receiving groove at an edge of the first active material layer. The first electrode tab is received in the first receiving groove, and is electrically connected to the first metallic layer. The thickness of the first electrode tab can be varied according to the electrical resistance desired. Thus, a high resistance of the first electrode tab is avoided.
