Lithium-free secondary battery

A lithium-free secondary battery is provided. The lithium-free secondary battery includes an anode, an electrolyte, a separator, and a cathode, the anode comprising an anode plate composed of an anode current collector and an insulating layer formed in contact with the anode current collector in a predetermined width along the outermost side of the anode current collector, and is capable of suppressing non-uniform growth of lithium metal layer from the anode at the time of charge and discharge and thereby providing improved safety and capacity retention rate.
