A battery electrode, and a method for fabricating the battery electrode are described. The battery electrode includes a lithium foil that is arranged between a first porous current collector and a second porous current collector. The first and second porous current collectors each defines a multiplicity of interstitial spaces, and the lithium foil is embedded in the interstitial spaces defined by the first porous current collector and in the interstitial spaces defined by the second porous current collector, thus enabling two-side functionality.
