High-Capacity Primary Battery for Extreme Environments Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-098 Topic Title: High-Capacity Primary Battery for Extreme Environments Proposal No.: N081-098-1076 Firm: MaxPower, Inc. 141 Christopher Lane Harleysville, Pennsylvania 19438-2035 Contact: Benjamin Meyer Phone: (215) 256-4575 Abstract: MaxPower��s goal during the Phase I program is to design and demonstrate the capability of a primary Li|CFx battery assembly that is capable of delivering in excess of 12 hours operation at -40,aC in a battery architecture that weighs less than 0.7 pounds and fits a 14 in3 envelope. Successful battery performance will hinge upon MaxPower��s expertise in manufacturing of thin electrodes and implementation into hermetically sealed hardware. The battery architecture includes implementation of SOC technology using commercially available Integrated Circuits with minimal power consumption and low cost impacts. The combined battery chemistry with SOC implementation will limit costs and overall product development time. The developed SOC circuitry will be able to project remaining capacity based on temperature and previous discharge rates. Additionally, the battery assembly will contain an imbedded LED display in the casing that will indicate to the user remaining battery capacity when initiated by push button. After demonstration of the feasibility of the selected chemistry and SOC implementation, MaxPower will use modeling techniques to project performances for Phase II prototype development and build. Benefits: Federal, state, local, fire department, fire responders, and homeland security can benefit from the successful development of this program. Our cost-effective approach in realizing this LMR is expected to have pronounced effect even in the commercial applciation areas. The proposed is really not chemistry dependent and expand to couple with other chemistries for the indented applications that required Mobile Radios. Return
