Abstract: Na-ion battery is one of the possible replacements for Li-ion battery for energy storage,due to its high energy density,high safety,and low cost. In this paper,research progress of Na-ion batteries is reviewed,including preparation and electrochemical performance of positive electrodes,negative electrodes and electrolytes. Positive electrodes include oxides,phosphates. Negative electrodes include carbon based-anodes,titanium based-anodes and alloy anodes. Electrolytes include organic electrolytes and gel polymer electrolytes. The advantages and limitations of materials are presented. Na-ion secondary battery could gradually replace Li-ion battery,and the present main problem is matching of different system materials.

Key words: Na-ion battery, positive electrode, negative electrode, electrolyte
