Aqueous sodium-ion batteries recently have been widely and deeply studied in the energy field due to their prominent advantages such as high safety, low cost and environmental friendliness. Remarkable progresses of aqueous sodium-ion batteries gradually encourage their process of industrialization. However, compared with the organic secondary ion batteries, the development of aqueous sodium-ion batteries is limited by the narrow stable voltage window of the electrolyte and the poor cycle stability of the electrode material. How to solve these problems is still the key to the development of aqueous sodium-ion batteries. The latest developments in electrode materials, electrolyte and current collector of aqueous sodium-ion batteries, as well as challenges and possible solutions for developing high-performance aqueous sodium-ion batteries are mainly summarized in this review. Furthermore, the development prospects of aqueous sodium-ion batteries are discussed.

Key words: aqueous sodium-ion battery, electrode material, electrolyte, energy density, cycling life
