Abstract
A MEMS volumetric lithium-ion battery formed using a soft lithography technique. The battery includes a reduced footprint area with a corresponding increase in capacity by exploiting the Z dimension through increased volume, while utilizing a chemistry capable of one Joule per cubic millimeter. The battery may be manufactured to cell sizes of one millimeter and cell volumes of one cubic millimeter. The battery can be formed into battery banks, electrically connected in series and parallel, and integrated into a system-on-a-chip. The battery may also be implemented for on-board applications and is suitable for space, air, and terrestrial applications, and in particular, for providing a MEMS volumetric battery.
