Abstract
Lithium metal anode protection, and various semi-fuel cell constructions for use in deep, high pressure seawater or air media are provided. The described lithium semi-fuel cells achieve record high energy densities, due to the high energy density of lithium anode and the use of the cathode reactant from the surrounding media, which is not part of the cell weight, and the use of ultralight and flexible packaging materials. These features make the described semi-fuel cells the ideal choice for powering underwater and air vehicles.
