R & D Activities

Electric Fuel is presently being funded within the framework of a BAA to develop high energy density 4th-generation zinc-air technology. Gen4 should be the ultimate design for a zinc-air cell and battery. The cell is simply an air cathode folded around a gelled anode, the cathode serving as the cell housing. The three open edges are sealed for leak-tight integrity. This can-less bi-cell technology, was initially demonstrated as a novel battery for the Marine Corps Warfighting Laboratory Dragon Eye UAV program. Now adapted for more moderate-power ground missions, with special focus as a battery for an integrated warfighter power source, gen4 zinc-air has demonstrated specific energies as high as 450 Wh/kg at the cell level.

Other R&D activities within the BAA framework include cathode and ionic liquid development for Lithium-Air.
