Abstract
Sodium-ion batteries (SIBs) have received great attention due to the low cost and abundance of sodium resources, and their chemical/electrochemical properties are similar to those of established lithium-ion batteries. In the past few years, we have witnessed the resuscitation and rapid development of various advanced electrode materials. Rationally designed nanostructures endow the electrodes with high reversible capacity, superior rate capability, and long-term cyclability. In this Review, we summarize some recent research progress in the rational design and synthesis of nanostructured electrode materials with controlled shape, structural complexity, composition, and boosted sodium storage performance. We seek to provide some understanding on the effect of nanostructure engineering on the sodium storage properties of electrode materials. It is thus anticipated that this Review will shed some light on the development of high-performance electrode materials for advanced SIBs.
