Abstract: A munition includes a munition body containing explosive material. An electronic subsystem is active between release and detonation of the explosive material. One or more batteries are electrically connected to the electronic subsystem to provide power to the electronic subsystem prior to detonation. The one or more batteries are positioned adjacent to the explosive material to be accelerated outward as corresponding munition projectiles after detonation, increasing the effective payload of the munition by performing dual functions. In one or more embodiments, the explosive material is cylindrically shaped and longitudinally aligned in a warhead section of the munition body. The one or more batteries are annularly positioned on lateral surface of the explosive surface to form a cellular fragmenting structure. In a particular embodiments, the munition body is a missile body containing a rocket propulsion system and the electronic subsystem comprises a missile guidance system.

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.

Abstract: A metal-air semi-fuel cell is provided, preferably based on lithium anode and a fuel cell type air/oxygen electrode immersed in an aqueous neutral, alkali or acid solution. The lithium anode is comprised of the active metal and one or more separators protecting the anode from reacting with an aqueous solution. The outermost layer on the lithium electrode is a solid-state lithium-ion conducting glass-ceramic which is impervious to and stable towards aqueous solutions. The cathode is comprised of an air or oxygen fuel cell type electrode in contact with the aqueous solution. The lithium anode of this invention also can be replaced by other electroactive metals which react with water and acids, bases and neutral solutions, such as metals from Groups 1 and 2 of the Periodic Table of Elements in addition to Zn, Mg, and Al.
