Chemical Physics of Electrochemical Energy Materials

Understanding the chemical physics of electrochemical energy materials is the key to improving the performance of energy storage and conversion devices such as batteries, fuel cells, electrolyzers, and supercapacitors. It is a multiscale problem that requires addressing fundamental issues on electric double layers and electrocatalytic processes at electrochemical interfaces at the atomistic level, structural dynamics of materials at in situ/in operando conditions, transport properties (mass and heat) of materials, degradation mechanisms of materials, optimization strategies for improving the overall performances at the device level, and more. In the past few years, significant progress has been made in the related areas owing to the fast development of characterization techniques, computational methods, and machine learning/big data technologies. In this special issue, we invite submissions of the latest efforts in all aspects of the topics mentioned above to highlight the importance of a fundamental understanding for electrochemical energy applications.
