- A three-dimensional (3D) electrode architecture for a microbattery includes an anode structure comprising one or more anode digits and a cathode structure comprising one or more cathode digits, the anode digits being positioned alternately with the cathode digits in an interdigitated configuration on a substrate, where each of the anode digits has a width w.sub.a and each of the cathode digits has a width w.sub.c. Each of the anode digits comprises an anode material deposited on a first current collector and extending to a height h above the first current collector, and each of the cathode digits comprises a cathode material deposited on a second current collector and extending to a height h, above the second current collector. A height-to-width aspect ratio h.sub.a/w.sub.a of the anode structure and a height-to-width aspect ratio h.sub.c/w.sub.c of the cathode structure are at least about 2.
