Liquid Ammonia Reserve Batteries for Electronic Fuzing

MaxPower believes that the introduction and successful development of a lithium metal anode based liquid ammonia battery system would be able to meet the power requirements for medium caliber fuze applications, especially the IRAP grenade application. The merging of established magnesium liquid ammonia and other lithium metal reserve battery technologies will provide the fundamental basis for the development work proposed. Challenges exist in regards to proper management of the lithium solvation rate in liquid ammonia along with proving cathode stability of traditional lithium based cathodes in an ammonia solution. MaxPower is confident that the detailed approaches through the use of electrolyte salt and supercritical fluid additives will make successful development achievable. Successful development of the proposed battery system will provide the US Army with solutions for medium caliber fuze applications that are not currently met by existing commercial batteries.
