Advanced Lithium-Water Battery for Electronic Countermeasure Devices.

摘要

The objective of this effort is to provide advanced battery technology leading to improved primary battery power supplies for Air Force applications. Anode alloys and cathode geometry were evaluated in lithium-water cells. The use of NH4F as a precipitant of LiOH in Li-water cells resulted in constant voltage discharges. Li-H2O cells in breadboard configuration discharged in excess of 45 min. at 1.2 V at 2A/sq in. Li utilization efficiency was greater than 70%. Li cells with H2O2 as cathode reactant delivered 45 min. of discharge at 2.5 V and 2A/sq in. Breadboard batteries discharged at 24 V but at less than design current because of flow equalization problems.
