A method of fabricating a negative electrode for an electrochemical cell may comprise: providing an electrically conductive substrate; depositing a metal layer on the substrate; anodizing the metal layer to form a porous layer on the substrate; depositing a layer of ion conducting material on the porous layer, the layer extending at least partially into pores of the porous layer; densifying the layer of ion conducting material; depositing a layer of alkali metal on the densified layer of ion conducting material; attaching a temporary electrode to the layer of alkali metal and passing a current between the temporary electrode and the substrate to drive alkali metal through the densified layer of ion conducting material to the surface of the substrate, forming an alkali metal reservoir at the surface of the substrate. Furthermore, an electrically conductive mesh may be used in place of the porous layer on the substrate. |
