Advance Lithium-Water Battery for Electronic Countermeasure Devices.

摘要

The lithium-water cell was characterized during the present study and marked improvements made in lithium utilization efficiency by the selection of electrolyte and in the cell potential by the use of catalyzed cathodes. Cell studies show that a spaced electrode cell can be operated with lithium hydroxide concentrations of 2.5-to 3.5-M in the electrolyte at 10to 30C at current densities to 1.5A/sq. in. About double this power density is expected with optimized cell construction. Selected electrolytes may be used that allow 50to 80% lithium-utilization efficiency at potentials of over 1 V at temperatures to 30degrees C. Catalyzed cathodes have reduced polarization and their use will increase by 10to 25% the power capability of the system. (Author)
