摘　　要：超级电容器是一种具有高功率密度、宽工作温度范围和出色循环稳定性等优点的新型储能设备。聚合物水凝胶因优异的离子电导率和力学性能,被广泛应用于新一代高性能超级电容器领域。其作为准固态电解质材料,能够克服电解液泄漏对电路造成的损害,同时促进器件的轻量化和集成化。本文以聚合物水凝胶的化学结构为切入点,综述了水凝胶电解质的结构对其力学性能及电化学性能的影响,并展望了其在超级电容器中的发展趋势。Supercapacitors are a new type of energy storage device with the advantages of high power density, wide operating temperature range and excellent cycle stability. Polymer hydrogels are widely used in the field of new-generation high-performance supercapacitors due to their excellent ionic conductivity and mechanical properties. As quasi-solid electrolyte materials, while overcoming the damage to the circuit caused by electrolyte leakage, they enable the lightweight and easy integration of devices. In this paper, starting from the chemical structure of polymer hydrogels, the influence of the structure of hydrogel electrolytes on its mechanical properties and electrochemical properties is reviewed, and its development trend in supercapacitors is prospected.
