A brief review on the pseudocapacitive storage and rate performance from the perspective of AZIB cathode materials. At last, an outlook is presented to promote the further development of AZIB cathodes.

A unique hybrid nanostructure of MoS₂@ACNTs is designed and fabricated as an anode material for sodium-ion batteries. With advantages of its unique constituents and architecture, the MoS₂@ACNT electrode is capable of exhibiting a high discharge capacity of 461 mA h g⁻¹even over 150 cycles at a current density of 500 mA g⁻¹.
