Abstract
The MK-48 torpedo requires a temporary crossover power supply until main engine activation and alternator power becomes available. Due to the low energy density, high cost, and deteriorating availability of presently used thermal batteries, a suitable replacement power source using innovative energy storage concepts is desired. Creare proposes to develop an innovative high density power source based on a nanophosphate lithium-ion battery chemistry. Nanophosphate lithium-ion cells have the benefits of high energy density and high discharge current capability without the safety concerns of oxide based chemistries. We propose to integrate a small number of nanophosphate lithium-ion cells with a high power density voltage converter to achieve high energy density, high reliability, compact size, safe operation, and lower cost than present thermal batteries. During Phase I we will work with key strategic partners to establish requirements and evaluate our concept with design, fabrication, and testing. During Phase II we will work with our partners to fabricate and demonstrate a high fidelity engineering prototype. Advantages of our approach include the use of very safe, high energy density battery materials and optimal use of support electronics to maximize reliability while minimizing size and cost.
