High-Capacity SnSb Alloy Anode Fabricated by Centrifugal Spinning Method Navy SBIR FY2016.1 Sol No.: Navy SBIR FY2016.1 Topic No.: N161-012 Topic Title: High-Capacity SnSb Alloy Anode Fabricated by Centrifugal Spinning Method Proposal No.: N161-012-0082 Firm: Storagenergy Technologies, Inc. 3666 W 2100 S Salt Lake City, Utah 84120 Contact: John Bi Phone: (801) 386-8555 Web Site: http://www.storagenergy.com Abstract: Metal-alloy based anode materials have much higher energy density and provide distinct advantages. However mechanical degradation and eventual failure of metal-alloy anode during electrochemical cycling lead to the loss of capacity, thus limiting its cycle life and commercialization. Storagenergy Technologies Inc. and North Carolina State University propose to design and develop a high-performance nano-structured metal-alloy anode material and a low-cost manufacturing process for Li-ion batteries. The goal of the Phase I project is to develop an encapsulated nanosized alloy/carbon porous nanofiber anode material with low cost, high safety, high capacity of >700 mAh/g, excellent cyclability, high coulombic efficiency and high rate performance. Benefits: The successful development of this anode materials technology will enable a high energy density battery with enhanced safety, rate performance and long cycle life, which will meet the requirement of naval craft battery. This high-performance battery can be widely used in defense, consumer electronic, electric vehicles and charging stations, tourist coaches etc. We believe that the new anode material will have a dramatic impact on the growth, profitability and international competitiveness of the U.S. battery industry and will create a significant number of high-tech jobs here in the United States.
