Abstract

Lithium-ion batteries (LIBs), the most successful secondary battery in the energy storage field, have been deeply and widely used in all aspects of life (such as transportation commuting, electronic products, and clean energy storage), but the development of the most commercially successful battery is in crisis due to the problems of high cost and resource shortage. Sodium has attracted attention in energy storage because of its rich resources and low price. However, sodium ions have a larger ion radius compared with LIBs, which results in worse ionic conductivity. Therefore, this characteristic of sodium ions has become an important factor restricting the development of sodium-storage electrode materials. Whereas the restriction of developing electrode materials in sodium-ion batteries (SIBs), the emphasis of research has focused on enhancing the electrochemical performance of high-performance anode and cathode materials and promoting the commercial application of SIBs. This paper will introduce the current research status and progress in cathode and anode materials of SIBs, and the future development direction of cathode and anode materials for SIBs will be summarized by analyzing the mechanism and defects of related electrode materials.
