Electrochemical cells may include electrodes (a cathode and an electrode) disposed on each surface of an electrolyte. Each of the electrodes and electrolyte can be a solid film that can be layered on top of each other to create a stacked structure disposed on a substrate. A polymeric encapsulant material can be applied over and around the cell stack, and a moisture barrier can be formed over the encapsulant material to thereby prevent moisture from reaching the cells. Conductive terminals electrically connected to the cathode and the anode, respectively, may be formed on the second side of the substrate. In this way, the battery can be flip-chip mounted to corresponding mounting pads, and thus connected to other electronic devices that receive power from the battery. |
