Electrochemical energy storage has played important roles in energy storage technologies for portable electronics and electric vehicle applications. During the past thirty years, great progress has been made in research and development of various batteries, in term of energy density increase and cost reduction. However, the energy density has to be further increased to achieve long endurance time. In this book, recent research and development in advanced electrode materials for electrochemical energy storage devices are presented, including lithium ion batteries, lithium-sulfur batteries and metal-air batteries, sodium ion batteries and supercapacitors. The materials involve transition metal oxides, sulfides, Si-based material as well as graphene and graphene composites.

Chunwen Sun is a Professor at Beijing Institute of Nanoenergy and Nanosystems (BINN), Chinese Academy of Sciences (CAS). He received his PhD degree in Condensed Matter Physics from the Institute of Physics (IOP), CAS in 2006. After graduation, he worked as a postdoctoral research fellow at Technische Universität München (TUM), Germany, then joined the Institute for Fuel Cell Innovation, National Research Council Canada (NRC) as a Research Associate Officer.
