Abstract
A negative electrode for a lithium metal battery which includes: a current collector; a negative electrode active material layer formed on the surface of a current collector; a heat conductive layer formed on a surface of the negative electrode active material layer wherein the heat conductive layer comprises a heat conductive material having a heat conductivity of 25 W/m·K to 500 W/m·K; and a protective layer formed on a surface of the heat conductive layer, wherein the protective layer includes at least one of a porous polymer layer and a ceramic layer. An electrochemical device including the negative electrode for a lithium metal battery. The negative electrode for a lithium metal battery includes a heat conductive layer and a protective layer, and can inhibit growth of lithium dendrite in a negative electrode for a lithium metal battery and improve the cycle life of an electrochemical device.
