Abstract
A solid-state battery and a method of making the same are disclosed. The battery includes a base frame or support, first and second exterior contacts on the base frame/support, stacked solid-state battery unit cells, first and second electrical connections, and encapsulation in contact with the base frame/support and covering the solid-state battery unit cells and the electrical connections. Each stacked solid-state battery unit cell is on a metal substrate and has exposed cathode and anode current collectors. The electrical connections respectively electrically connect the exposed cathode and anode current collectors to the first and second exterior contacts. The method includes forming the stacked solid-state battery unit cells on the base frame/support, forming the exterior contacts on the base frame/support, electrically connecting the exposed cathode and anode current collectors to the respective exterior contacts, and encapsulating the solid-state battery unit cells and the electrical connections.
