摘　　要：水系电解液由于其安全性高,成本低的优点在电解液市场上具有一定优势,但其受到水的分解电压(1.23 V)限制,导致器件输出电压及能量密度与其他电解液相比仍是短板。近年来,water-in-salt型电解液因其能达到3 V以上的宽电压而广受关注。越来越多的学者将water-in-salt型电解液应用到不同的电化学器件中,针对近年来water-insalt及其衍生电解液在不同类型器件中的应用以及发展进行了总结与展望。The aqueous electrolyte has certain advantages in the electrolyte market due to its high safety and low cost,but it is limited by the decomposition voltage of water(1.23 V),resulting in the output voltage and energy density of the device are still shortcomings compared with other electrolytes.In recent years,water-in-salt electrolytes have attracted much attention due to the wide range of voltages in excess of 3 V.More and more scholars have applied this strategy to different electrochemical devices.The application and development of water-in-salt and its derived electrolyte in different types of devices in recent years were summarized and prospected.
