    摘要： 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.

    摘要： A high solids content paste for fabrication of secondary battery electrodes may comprise: a negative active material or a positive active material; a binder; a solvent; and a hyperdispersant; wherein the high solids content paste has a specific viscosity chosen for a particular coating tool and a composition such that the high solids content paste will maintain a deposited shape after coating at least until the high solids content paste has dried and wherein the dry coating thickness is in the range of 5 microns to 300 microns. The high solids content paste with negative active material has a viscosity in the range of 30,000 cP to 45,000 cP and a corresponding density of 1.40 g/cc to 1.43 g/cc. The high solids content paste with positive active material has a viscosity in the range of 25,479 cP to 47,184 cP and a corresponding density of 2.72 g/cc to 2.73 g/cc.
