An Electric Field Assembler System for Micro-Nanofabrication of Energy Storage Materials

Traditional methods have limitations for the fabrication of micro-ordered batteries for use in a variety of applications including biomedical and healthcare devices. A new micro-nanofabrication method and system that combines deposition, layering, and patterning processes has now been developed for production of micro-ordered energy storage battery devices and materials. Here, we show an electrical field directed (EFD) deposition array device with a 500 μm active assembly area containing 25 microelectrodes. Using EFD assembly, we demonstrated the patterned deposition of graphite mixtures in water-based and solvent-based solutions. The graphite mixture patterns were confirmed by SEM imaging.
