Sodium-ion batteries are promising energy storage and conversion systems due to the wide availability and low cost of sodium resources. It is assumed that sodium-ion batteries will be widely used for large-scale energy storage devices in the future. The lecture will provide an overview of the study of high-capacity functional materials (cathode and anode) for sodium-ion batteries. Promising high-capacity functional materials for sodium-ion batteries are considered taking into account their multi-electron reaction with sodium ions. The lecture will highlight the problems of high-capacity functional materials, including their low electron and ion conductivity, adverse interactions with the electrolyte, significant changes in the volume at sodium introduction, poor cyclability. Ways to improve high-capacity functional materials, such as the using of carbon coatings, architectural design, doping, modification of the electrolyte will be pointed.
