The electrode piece includes a current collector and a functional layer located on a first surface of the current collector, the first surface is provided with a tab, and the functional layer is composed of a normal area away from the tab and a recessed area near the tab, and a thickness of the recessed area is less than a thickness of the normal area. The present disclosure can effectively prevent problems such as excessive thickness of part of a cell near the tab, thereby improving battery qualities such as safety and charging/discharging rate.",
