Overview of the D.O.E. Energy Storage R&D: Status for FY 2006

This paper presents an overview, including highlights and accomplishments, of the energy storage RD which are organized to complement each other. The developer program is conducted in collaboration with battery developers and original equipment manufacturers (OEMs) and includes benchmark testing, technology assessments, and system development. Applied battery research is focused on addressing cross-cutting barriers for high-power lithium-ion systems, which include the barriers of insufficient life, inadequate low temperature performance, inability to tolerate abuse, and a high cell-level cost. Focused fundamental research addresses critical problems of chemical instabilities for advanced batteries and attempts to better understand why systems fail, develops models to predict system failure and to enable optimization, and researches promising new materials. The paper also describes DOE’s current energy storage R&D coordination efforts with other agencies.
