Abstract
Microscopic batteries, integratable or integrated with microelectromechanical systems or other microscopic circuits, including a MEMS microcircuit, and methods of microfabrication of such microscopic batteries are disclosed, among which comprise closed system microscopic batteries for internal storage of electricity using interval reactants only, which comprise microscopic electrodes, electrolyte and reservoir for the electrolyte.
Claims20
An energy storage microscopic rechargeable battery having internal only chemical reactants, the battery having a volumetric size comprising a micrometer footprint adapted for direct and congruent size integration with microelectromechanical systems and/or microcircuitry to reduce power losses, the microscopic rechargeable battery comprising etched spaced electrodes of reactant material comprising microscopically sized footprints as low as 0.001 cm2 with an microscopic space containing electrode reaction accommodating electrolyte interposed between the spaced reactant electrodes.
An internal electrical energy storage microfabricated rechargeable battery comprising a volumetric microscopic size including a micrometric-sized footprint directly size and electronically integrated into a microelectromechanical system or non-microelectromechanical system microcircuit to alleviate power losses, the battery comprising at least one electrical energy storage cell comprised of reactants in the nature of separated internal microfabricated electrodes each having a footprint within a range of less than 1 cm2 to 0.0001 cm2 of reactant material etched and patterned in place to define an internal microfabricated electrolyte storage space between the etched microfabricated electrodes.
