Liquid Ammonia Reserve Batteries for Electronic Fuzing

MaxPower believes that the introduction and successful development of a liquid ammonia-based battery system utilizing a lithium metal anode would be able to meet the power requirements for medium caliber fuze applications, especially the IRAP grenade application. During Phase I development, we have demonstrated 3 V load voltages through the use of a lithium metal anode and superconcentrated electrolyte in combination with the recently developed high voltage persulfate cathode. The persulfate cathode was still able to reach the 3 V requirement without being optimized. We are confident the performance can be further improved to fully meet the electrochemical requirements. In addition, MaxPower’s extensive experience in hardware engineering for lithium reserve batteries has us well positioned to handle the challenges that could exist in battery design and development. Successful development of the proposed battery system will provide the US Army with a workable solution for medium caliber fuze applications.
