Abstract
The U.S. Air Force requires rechargeable thermal battery technology that can function at low skin temperatures for use in advanced weapons systems. Based on proof-of-concept experiments conducted by us, we believe that a rechargeable thermal battery technology may be achieved by marrying "off the shelf" lithium ion battery electrodes to a new class of non-flammable molten salt electrolytes. We envision a lithium ion cell chemistry operating at ~100¿C that can provide high energy densities and high rate capabilities with battery skin temperature significantly lower than that of current thermal primary batteries. During Phase I the new molten salt electrolytes will be characterized in respect to ionic conductivity and electrochemical stability. The best electrolytes will be cycled in lithium ion cells at elevated temperatures.
