This exploratory program researches the feasibility of new cathode materials to improve battery performance in vehicles and other weight-sensitive applications. Unlike typical transition metal oxide materials currently used in lithium battery cathodes, these high voltage metal and metal-metalloid alloys will have a lower weight and thus improve the specific energy of batteries. The research will explore the feasibility of making lithium alloy cathodes using various chemical and electrochemical methods. It is anticipated that preliminary results from this work will reveal whether there is a convincing pathway for battery cathode materials of the type investigated in this study to have the potential for impact at scale.
