Lithium-ion (or rocking-chair) batteries with lithiated oxide cathodes and carbon anodes are finding increasing acceptance in many electronic applications including low rates (e.g., memory backup, real time clock, bridge function) and high rates (e.g, laptop computers, cellular phones, camcorders, etc.). This technology offers significant improvements in safety relative to cells using lithium metal anodes, with only a modest reduction in energy density. In general, materials for lithium-ion cells are chosen to minimize the energy density penalties associated with replacing the lithium electrode with an intercalation electrode. In this review paper, the authors describe the properties of the cathode, anode and electrolyte, and discuss requirements for improved materials for advanced lithium-ion systems. Consideration is given to energy density, rate capability, cycleability and thermal stability.
