High Voltage Lithium Ion Reserve Battery Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-092 Topic Title: High Voltage Lithium Ion Reserve Battery Proposal No.: N142-092-0480 Firm: ADA Technologies, Inc. 8100 Shaffer Parkway Suite #130 Littleton, Colorado 80127-4107 Contact: Stephen Cordova Phone: (303) 874-8222 Web Site: www.adatech.com Abstract: Thermal batteries are primary batteries containing solid cathodes and anodes sandwiched around an inorganic solid electrolyte that remains inert under ambient conditions until melted using pyrotechnic materials. Today's SOTA thermal batteries rely on complex, heavily engineered systems with large parasitic masses/volumes due to the need for high operating temperatures and thermal retention to maintain those temperatures. Additional volume and complexity is also required for the prevention of catastrophic misfiring and failure from operation at those same high temperatures. This leads to significantly low energy densities compared to Li-ion chemistries. To address this need, ADA Technologies, Inc. propose the development of a chemical reserve Li-ion battery that represents a disruptive change in reserve battery design and could potentially eliminate future demand for thermal reserve batteries. The technology has the potential to provide 3-4x more energy and power than current thermal reserve batteries due to the utilization of high energy/power density Li-ion battery chemistries. These innovations have the potential to enable a substantial improvement in all critical performance criteria for next-generation reserve batteries - including the ability to operate over a wider range of temperatures and operating conditions, enhance safety, lower cost and provide a flexible design. Benefits: Li-ion reserve batteries offer significantly higher (3-4X) energy and power densities compared to thermal batteries, while providing 20+ year shelf-life and fast activation times (<1s). Such batteries can potentially replace comparatively heavier (3-4X), larger (3X volume) thermal battery systems for smart munitions (to drive embedded electronics, guidance systems and tracking devices). Examples of military application include Joint Direct Attack Munition (JDAM) bombs, air-to-surface, air-to-air and surface-to-air missiles, guidance systems and global positioning support for gun-fired PEO ammunitions. In addition, such systems can be incorporated into next-generation mines, countermeasure devices and sonobuoys. Applications are mainly military, with some replacement of commercially used thermal batteries used in underwater research devices. Return
