Keywords: Lithium, air, water, high energy density


PolyPlus Battery Company is developing novel lithium/air batteries with unprecedented energy density, rivaling that possible for hydrocarbon fuel cells. The technology is based on proprietary encapsulated water stable lithium metal enabling the practical realization of unique galvanic couples such as Li/Air and Li/Water batteries. The theoretical specific energy of lithium metal/aqueous couples is greater than 10,000 Wh/kg and commercial batteries are expected to exceed 1000 Wh/l and Wh/kg.
