Editorial: Interface and structure designs of electrode materials for advanced electrochemical energy storage

The increasing demand for mobile power supplies in electric vehicles has motivated intense research efforts into developing high-performance electrochemical energy storage (EES) devices. However, current EES technologies do not meet the requirements for various applications of improved performance and safety and reduced cost and environmental footprint. Advanced materials, including active anode and cathode materials, inactive carbon and binding additives, metal current collectors, separators, and electrolytes, play essential roles in supporting battery operations. Particularly, the interface engineering of distinct phases or components in composite electrodes and electrolytes, as well as the hierarchical structure design for each component or multi-component device, can address many fundamental Research Topic associated with the charge transport kinetics, electrochemical characteristics, and chemical/physical/mechanical properties. Therefore, it is possible to improve the energy storage performance, reliability, and safety by investigating the interface and structure.
