Solid state fiber-based battery system and method of forming same

Abstract:

A solid state battery system and methods of forming a solid state battery system. The solid state battery system has a plurality of fiber battery cells formed into a pattern. Each fiber battery cell has a fiber inner core which may be a carbon-graphite, carbon-nanotube, boron-nanotube or boron-nitride-nanotube fiber and serves as the anode. In addition, the fiber battery cell has an electrolyte layer formed over the fiber inner core and an outer conductive layer (the cathode) formed over the electrolyte layer. A first terminal is electrically coupled to the fiber inner core of each of the plurality of fiber battery cells. A second terminal is electrically coupled to the outer conductive layer of each of the plurality of fiber battery cells. The solid state battery system may be incorporated into a composite part for a vehicle, such as an aircraft.
