Advanced Modular, Energy Storage Technology Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-053 Topic Title: Advanced Modular, Energy Storage Technology Proposal No.: N091-053-0675 Firm: Altairnano, Inc. 204 Edison Way Reno, Nevada 89502-2306 Contact: Veselin Manev Phone: (775) 858-3738 Web Site: http://www.altairnano.com Abstract: The SBIR Phase I proposal is designed to improve the high end temperature performance of Altairnano''''s nano Lithium titanate batteries and will develop an equivalent circuit model capturing the transient dynamics of Altairnano's 50 Ah cell. Altairnano will study the effects of various materials and the interactions between them to determine the best electrode material combination in order to eliminate gasses that are created at temperatures above 55 degrees Celsius. This research will attempt to accomplish this without sacrificing other performance attributes, such as long cycle life and high power rates, currently seen in existing Altairnano products. These objectives are intended to align with the Navy's goal of developing a multipurpose energy storage module for a variety of shipboard applications ranging from single generator operations to pulse power applications. Benefits: Upon completion of the SBIR objectives, Altairnano will be able to produce an energy storage system for single generator operation (SGO) that will enable the Navy to take advantage of the numerous SGO benefits. The improvements in elevated temperature durability will allow more flexibility of ship design. This will make the battery system ideal for integration throughout the Navy's fleet. Currently, surface combatants have a primary gas turbine generator system as well as two redundant generators serving as back-up. One of these back-up systems is constantly running providing continuity of power should the primary system fail. By implementing the Altairnano energy storage system the need for running a back-up system would be eliminated, allowing for SGO. It is estimated that enabling a ship for SGO would, in addition to maintenance cost reductions, result in annual fuel cost savings of $600 thousand to $1.8 million depending upon oil prices. These fuel savings, while reducing American dependence on foreign oil and lowering harmful greenhouse emissions will also provide the Navy with substantial through-life cost benefits. Return
