Claim:
1. A method of fabricating a three-dimensional (3D) porous electrode architecture for a microbattery, the method comprising: forming a microbattery template comprising: infiltrating interstices of the first lattice portion with a first conductive material and infiltrating interstices of the second lattice portion with a second conductive material, each of the first and second conductive materials filling the interstices to reach a predetermined thickness on the substrate; removing the solid structure and the lattice structure from the substrate, thereby forming first and second conductive scaffolds from the first and second conductive materials, the first and second conductive scaffolds comprising a porosity defined by the lattice structure and having a lateral size and shape defined by walls of the solid structure.
