摘 要：Our overall goal is to increase the capabilities of today s long- rage Unmanned Underwater Vehicles (UUVs) and Unmanned Underwater Gliders (UUGs) by using high-energy-density lithium-seawater batteries. Specific objectives are (1) to test in the laboratory and ocean new lithium-seawater batteries developed and manufactured by the PolyPlus Battery Company, (2) to discover how to mount and operate these cells to minimize adverse impacts of limited mass transfer with the ambient seawater and of bio-fouling, and (3) to develop a long-range underwater UUV or UUG to exploit this energy source. Our target is to double the range/duration of long-range neutrally buoyant underwater vehicles.
