• The high demands for rechargeable lithium ion batteries (LIBs) have significantly increased each year for mobile electronics, electric vehicles, and stationary energy storage over the past two decades as a convenient power source. In order to fulfill the demands in these applications, tremendous research progress has been made at stabilizing new electrode materials with high performance and identifying the fundamental failure mechanisms that prevent a prolonged cycle life. Alloy and conversion materials with high specific capacity like silicon, sulfur, and conversion metal oxides have the most promise to increase the energy density of LIBs, but also have scientific challenges to retain their theoretical capacities upon repeated charge and discharge cycles. These new electrode materials have created a high interest for experimental techniques that are able to provide direct, atomic-scale, and real time observation during the electrochemical processes.
