Abstract: Naval Facilities Engineering Command (NAVFAC) has need for a robust stationary electrical energy storage (EES) device with the best properties of both rechargeable batteries and electrochemical ultracapacitors; having energy density of 500 W/l, ability to deliver high power pulses of 5 kW/l, and capability to achieve 25,000 full depth of discharge cycles. There is also an emerging need for improved EES technology in the commercial electric power industry, where it is needed for integrating with variable output renewable sources such as wind and solar, and for both distributed and centralized siting in support of a more efficient and smart electricity generation and distribution grid. TIAX proposes to develop such an electrochemical EES device meeting the above energy, performance and life metrics. TIAX has already demonstrated the inherent ability of advanced active materials to deliver the levels of performance required in such a hybrid device, and the proposed program will demonstrate feasibility of developing an energy storage device that incorporates these materials to deliver that performance, and to do so with technologies that will yield manufacturing cost of less than $500 per kWh.
Benefits: The novel TIAX electrical energy storage device will enable the Navy to meet electrical energy storage requirements for its infrastructure applications ranging from utility-level base power needs to high energy pulsing for electrically powered weapons. This will enable the Navy to achieve cost-effective distributed power for its basing and weapons siting operations. This technology will also have high value in the non-military commercial sector, particularly for applications such as distributed energy storage and for electric drive vehicles, which require both high energy and high power, but in which space is at a premium and added weight from batteries must be minimized. As such, these EES devices can benefit national security in terms of energy, economic and environmental security as well as in terms of national defense capabilities.
