Advanced Asymmetric Electrochemical Supercapacitor Energy Storage Technology Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-053 Topic Title: Advanced Asymmetric Electrochemical Supercapacitor Energy Storage Technology Proposal No.: N091-053-1647 Firm: New Span Opto-Technology Inc. 16115 SW 117th Ave. A-15 Miami, Florida 33177-1615 Contact: Sam Sun Phone: (305) 235-6928 Web Site: www.new-span.com Abstract: To address the U.S. Navy��s solicitation for shipboard compliant high energy storage system, New Span Opto-Technology Inc. proposes to develop Advanced Hybrid Electrochemical Energy Storage (AESES) technology. The AESES is comprised of a foamed aluminum oxide ceramics anode and a conductive polymer cathode. The anode is made highly porous for higher capacitance. The cathode is made of an aligned pattern of polyaniline nanofiber arrays covalently bonded with the substrate, with high current and ion conductivity and lower internal resistance, resulting in high energy and power density of AESES. The device is engineered with an operation potential of 20-60 Volts and a total capacitance of 5-20 Farads. The AESES will have energy density �r 150 Wh/Liter (~24J/cm3), power density up to 2,000 W/Liter lasting �r 5 min, cycling life �r 10,000 times, at environmental temperature up to 150 F (60 �XC). In Phase I we will demonstrate the feasibility of the AESES concept by fabricating a prototype module, capable of being incorporated into a power electronics and ship interface module. The comprehensive performance of the AESES module will be evaluated. The Phase II development approach and schedule that contains discrete milestones for product development will be provided. Benefits: The successful development of the proposed AESES technology can provide a cornerstone in producing asymmetric hybrid electrolytic and electrochemical supercapacitor. The AESES system possesses much improved energy and power densities, meeting U. S. Navy��s high energy and power densities requirements. Meanwhile, it can provide a universal means in civil products development, with tremendous theoretical and practical application significances. Return
