Abstract: Aqueous sodium ion battery (ASIB) shows good potential for stationary energy storage applications because it offers benefits in safety, environmental impact, cost, and durability. The development and commercialization of ASIB are getting more and more active worldwide as one of the key technologies towards adoption of renewable energy (solar and wind) and smart grid. This review summarizes the R&D history, theory, current technologies, and commercialization status of ASIB. Meanwhile, some cases of demonstrations and commercial applications are also introduced briefly. In addition, the strategies on further developments of key technologies are proposed. After years of rapid development, a series of electrode materials with high capacity and cycle stability has been developed. Through the design and optimization of the battery system, increase of energy density and decrease of manufacturing cost have also been achieved, therefore, commercialization has taken shape. Although ASIB is not a mature technology yet, recent achievements by the academia and industry show great potential for future application.
