Abstract: Sodium ion batteries are now actively developed as a new generation of electric energy storage technology because of their advantages of resource abundance and low cost. Particularly for large scale stationary electric storage, aqueous Na-ion batteries display better safety, lower cost and better environmental compatibility, providing a great prospect for widespread applications. However, there exist a number of difficulties in the development of Na-storage materials and aqueous Na-ion technology. To solve these problems, this review analyzes the different chemistry of the Na-storage materials and their electrochemical reactions in aqueous electrolytes, and discusses the recent development of Na+ host materials and aqueous Na-ion batteries. In addition, based on our experience and understanding, possible strategies are proposed for further development of low cost and pollution-free materials for aqueous Na-ion batteries.
