Research Institution

The Phase I program demonstrated potential of developing a Li-air battery by using an oxygen selective membrane (OSM) air cathode. The OSM cathode can access oxygen easily while resisting permeability and diffusion of moisture to the electrolyte and the lithium electrode. Successful Phase I efforts have provided the scientific and technological groundwork for further technology advancement in Phase II. In Phase II, US Nanocorp will (1) fabricate scale up production of Li-air battery components; (2) design the structure of the Li-air batteries and construct 150Ah-30 V prototype batteries, and (3) demonstrate prototypes having high energy density of >800Wh/kg and cycle life > 360 with reliable and safe operation. The objectives of Phase II will continue to refine the Phase I demonstrated feasibility, to a point where performance is sufficient to permit an assessment of ultimate application potential to meet MDA’s needs on High Altitude Airship (HAA) application and other commercial applications. Ultralife Batteries, Inc (UBI), the Phase II commercialization partner, will lead in prototype battery fabrication and evaluation. UBI has pledged $150,000 cost share to the Phase II and will carry the follow-on $250,000 investment for full commercialization of this new battery technology, contingent on Phase II milestones being met.
