Lithium metal powder-carbon powder composite anode for lithium secondary battery and lithium metal secondary battery comprising the same

Abstract

Provided are an anode in which lithium metal powder and carbon powder are physically mixed with each other to form a composite and the composite is applied as an anode layer, and a lithium metal secondary battery including the anode. The anode of the present invention may suppress the formation of lithium dendrites and the change in volume of cells generated in a rechargeable battery which uses a lithium metal anode and significantly improve the cycle life-span of a lithium metal secondary battery by physically mixing lithium metal particles and carbon particles having an equivalent average particle diameter with each other to be applied as an anode layer.
