Abstract

Disclosed is an anode-free lithium secondary battery having an anode current collector coated with an artificial SEI layer, and specifically, an anode-free lithium secondary battery including an anode current collector coated with an artificial SEI layer formed of a metal. Provided is an anode-free lithium secondary battery that is capable of suppressing formation of dendrites on an anode current collector and of improving the capacity and lifespan of the battery by coating the anode current collector with an artificial SEI layer.
