Extended Shelf-life Primary Battery for LMAMS

Under SBIR Phase II Enhancement AMRDEC (M) Contract W31P4Q-10-C-0295, American Energy Technologies Co. (AETC) is focused on a primary battery with extended shelf-life targeted for Lethal Miniature Aerial Missile System (LMAMS).Notable technical achievements include demonstration of an improved cylindrical cell Li/CFx-MnO2 chemistry with significant increase in power density and requisite low temperature performance that approaches the challenging LMAMS power and volume requirements.To overcome these remaining hurdles, AETC identified a novel true prismatic cell and accompanying battery design that can meet LMAMS physical and environmental parameters according to analysis.. The remaining technical objective is implementing a form-factored cell-level design that reduces Equivalent Series Resistance (ESR) and improves battery performance, while retaining high energy and low temperature capability. The final product deliverable will represent a maintenance-free, safe, flight worthy, environmentally benign design.Application of new generation conductivity enhancement additives, along with the precise engineering of porosity in electrodes, and with other optimizations, is expected to boost systems projected power density to values comparable to those of lithium-ion and thermal reserve batteries.
