LITHIUM ELECTRODE AND LITHIUM SECONDARY BATTERY COMPRISING SAME

The present invention relates to a lithium electrode and a lithium secondary battery comprising the same, and more particularly, it suppresses the formation of dendrites by providing a protective layer containing the two-dimensional material and the polymers of intrinsic microporosity on the surface of the lithium metal layer and improves the transfer characteristics for lithium ions, making it possible to prolong the lifetime of the lithium secondary battery.
