摘　　要：水系钠离子电池因为拥有安全性高、环境友好且造价成本低等特点受到广泛关注,被认为是一类极具发展潜力的新型储能体系。鉴于此,本研究使用简单的液相共沉淀法制备典型的普鲁士蓝类似物–铁氰化镍作为储钠活性材料,系统研究铁氰化镍在天然海水和0.5 mol/L氯化钠溶液中的电化学性能,阐明廉价天然海水作为水系钠离子电池电解液的可能性,进一步降低水系钠离子电池的成本,提高其应用价值。Owing to the high safety, environmentally friendly and low cost, aqueous sodium ion battery has been regarded as a promising energy storage system. Therefore, this study used a simple liquid phase co-precipitation method to prepare the typical Prussian blue analogue-nickel ferricyanide. And the electrochemical properties of derived nickel ferricyanide were measured in the electro-lytes of 0.5 mol/L NaCl and natural seawater. These results reveal the possibility of natural sea-water as the electrolyte of aqueous sodium ion battery. The application of natural seawater elec-trolyte would reduce the cost of aqueous sodium ion battery and increase its application value.
