3. High structural and chemical stability to ensure good cyclability.
4. High electronic and Na-ion conductivity to realize rapid charge/discharge.
5. Mass production convenient, resource abundant, and environment benign.

A wide variety of compounds have been investigated for cathodes used in Na-
ion batteries. In this section, we mainly focus on metal oxides, polyanion com-
pounds, and metal hexacyanides.
