Rechargeable Li-ion cells present the highest energy and power density of any commercial battery technology.  Considerable materials research is being conducted at Argonne to extend Li-ion battery technology to hybrid electric vehicles (HEVs), plug-in HEVs, and battery electric vehicles (EVs), wherein the challenge is to achieve extended driving range (i.e., high energy), high charge/discharge rates (i.e., high power), and long calendar life (i.e., high stability) in a safe and cost-efficient manner. Various lithium-ion battery chemistries, including negative electrodes with various graphite morphologies, positive electrodes containing layered– and spinel–oxides, and electrolytes containing various salts and additives are being examined at Argonne. This presentation will highlight electrode combinations that yield high energy densities and power densities, with a focus on graphite and carbon materials, and identify their role in performance and performance degradation. Strategies to design safe, long-life, lithium-ion batteries will also be described. <br/>
