Organosilicon Compounds for Reduced Flammability Lithium Ion Battery Electrolytes Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-031 Topic Title: Organosilicon Compounds for Reduced Flammability Lithium Ion Battery Electrolytes Proposal No.: N101-031-1676 Firm: Silatronix, Inc. 3591 Anderson Street Suite 209 Madison, Wisconsin 53704-2542 Contact: Michael Pollina Phone: (608) 301-5064 Web Site: www.silatronix.com Abstract: Silatronix has developed novel organosilicon compounds that can be used as drop-in replacements for conventional carbonate electrolytes in lithium-ion cells. These organosilicon electrolytes have very high flash points and have demonstrated superior stability and safety characteristics. In the course of this research, Silatronix will optimize the composition of these electrolytes to meet the specific power, lifetime, and operating temperature requirements established in the solicitation. Working with commercial partners, we will deliver a system that provides superior safety at a cost and performance levels similar to current electrolytes. Benefits: Successful completion of this work could lead to the development of energy storage batteries with improved performance and enhanced safety for a number of DoD high energy applications. The low flammability and low toxicity of organosilicon compounds provides an inherent margin of safety over existing electrolytes and is particularly important to DOD applications where they may be subjected to extreme temperatures and where the low flammability could improve personnel safety. The attractive performance and safety characteristics could facilitate more widespread application to civilian transportation and power utility markets. Return
