Progress in electrode materials for the industrialization of sodium-ion batteries

In recent years, sodium-ion batteries (SIBs) have received renewed attention due to the continued rise in lithium prices. SIBs are promising to replace lithium-ion batteries under various application scenarios, such as large-scale energy storage systems and low-speed electric vehicles. As the core of SIBs, electrode materials are the key factor demining the electrochemical performance. Key drawback, including cycle stability, air stability and energy density, are refraining the development of SIBs off-industrialization. For a systematic understanding on the development of SIBs, in this review, we summarized the progress of SIBs from the industrialization viewpoint, including the fabrication methods suitable for large scale production of electrode materials of SIBs, and the optimization strategies to improve electrochemical performance. Finally, we proposed promising directions for future development of electrode materials for SIBs toward industrialization.
