Abstract
A lithium electrode includes a protective layer containing an ion conductive electrolyte in the interior and on the surface of the electrically conductive matrix. The protective layer may make the electrical conductivity of the surface of the lithium electrode uniform, imparts strength during the growth of lithium dendrites, physically prevents the growth of lithium dendrites, and suppresses the generation of dead lithium.
