Materials for high-energy density batteries

Abstract

Lithium-ion batteries have emerged as the choice of rechargeable power source as they offer much higher energy density than other systems. However, their performance factors such as energy density, power density, and cycle life depend on the electrode materials employed. This chapter provides an overview of the cathode and anode materials systems for lithium-ion batteries. After providing a brief introduction to the basic principles involved in lithium-ion cells, the structure-property-performance relationships of cathode materials like layered LiMO2 (M =Mn, Co, and Ni) and their soiled solutions, spinel LiMn2O4, and olivine LiFePO4 are presented. Then, a brief account of the carbon, alloy, oxide, and nanocomposite anode materials is presented. © 2009 Springer US.
