Recently, many researchers focus on Na-ion batteries as an alternative to Li-ion batteries, owing to their low cost and high natural abundance. However, they suffer from low electrochemical performance and large volume expansion, which makes difficult to industrial application. Therefore, various strategies have been proposed to address the current issues, such as particle-size control, surface-coating, and application of electrode material with various crystal structures. Herein, we briefly introduce and discuss the recent research with development trend of cathode material for Na-ion batteries.
