The rapid development of portable electronics and hybrid electric vehicle (HEV) markets promotes the research of electric energy storage systems. Among them, lithium-ion batteries (LIBs) have attracted intense attention, due to their high energy density and long cycle lifetime. The demand for higher energy density LIBs facilitate the study of various electrode materials. Performance optimization of electrode materials necessitates information about structural evolution of electrode materials at an atomic scale. However, limited understanding for the structural evolution of electrode materials at atomic resolution, especially the Li ions distribution and arrangement at the atomic level, underlying electrochemical process substantially hinders our exploration of reaction mechanism and further performance optimization.
