Rechargeable lithium ion batteries offer large performance improvements in power and cost for many fleet systems, but safety requirements place significant limitations on the use of lithium ion batteries particularly large batteries. The proposed R&D will improve the safety to meet submarine and aircraft requirements and enhance performance of batteries for UUVs by advances in 3 areas: cell control, battery management, and cell chemistry and packaging. The Phase II work will result in safety and performance testing of the batteries and development of increased energy density. Phoenix International, Inc. and Lithium Technology Corp. will build on their state-of-the-art pressure tolerant and lithium ion technologies to make this next generation UUV battery that will improve UUV operation and safety
Benefit: The work will result in UUV batteries that meet submarine and aircraft safety requirements with improved energy density, reliability at lower life cycle and mission costs compared to current UUV batteries.
