Abstract: As the rapid growth of lithium-ion battery (LIB) market raises the concern about limited lithium resources, rechargeable sodium-ion batteries (SIBs) are attracting growing attention from the field of electrical energy storage due to the large abundance of sodium. Compared with the well-developed commercial LIBs, all components of the SIB system, such as the electrode, electrolyte, binder, and separator, need further explorations before reaching the practical industrial application level. Drawing lessons from the LIB research, the SIB electrode materials are being investigated extensively, yielding tremendous progress in recent years. Our group has proposed and investigated a variety of new electrode materials for SIBs, including transition metal oxides with layered or tunnel structure, and organic molecules systematically. Several promising materials with moderate energy density and ultra-long cycling performance are demonstrated. Appropriate doping and/or surface treatment methodologies are developed to effectively promote the electrochemical properties. These advanced electrode materials with excellent sodium storage would accelerate the application of sodium-ion batteries in the large-scale energy storage systems.
