Abstract

Provided herein are multilayer solid-state lithium ion batteries and methods of fabrication. In some embodiments, units of preformed cell elements and a current collector (of either the anode or cathode) are stacked. The preformed cell element includes a double-sided electrode, with separator/electrode on both sides of the double-sided electrode. The double-sided electrode may be an anode or a cathode. During the stacking process, the preformed cell elements are laminated to a cathode current collector or an anode current collector, as appropriate.
