A general micro-molding approach based on MEMS fabrication has been introduced to fabricate 3-dimensional (3-D) electrodes for microbatteries. Batteries based on 3-D microstructure are shown to offer significant advantages (e.g., small areal footprint and short diffusion lengths) in comparison to the conventional 2-D thin film batteries. In this paper, microelectrodes for Li-ion and Ni-Zn batteries have been fabricated and tested
