摘　　要：由于在电化学能源存贮与转化器件中所展现出的巨大潜在应用前景,固态聚合物电解质膜的开发受到研究界的广泛关注。基于柔性储能与转换器件的发展,以聚乙烯醇(Polyvinyl alcohol, PVA)为基体的凝胶聚合物电解质(Gel polymer electrolytes, GPEs)因亲水性强,无毒,良好的兼容性以及优异的化学稳定性,是当前研究较多的理想电解质材料。本文从PVA基水凝胶电解质的制备合成原理、方法和性能表征出发,总结和讨论了其基本物理特性和电化学性能,并就PVA基水凝胶电解质在超级电容器、柔性锌空电池、锂离子电池以及太阳能水热电池中的研究和应用进展进行了综述,并对其在该领域未来的发展做出展望。Development of high-performance solid polymer electrolyte membranes (SPEMs) is a subject of intense research owing to its promising applications in electrochemical energy storage and conversion devices. Gel polymer electrolytes (GPEs) based on polyvinyl alcohol (PVA) are ideal electrolyte materials owing to their strong hydrophilicity, non-toxic, good compatibility and excellent chemical stability. In this paper, the preparation and synthesis of PVA based hydrogel electrolytes are summarized, and their basic physical properties and electrochemical properties are discussed. Specifically, the research progress of PVA based gel electrolytes in supercapacitors, flexible zinc air batteries, lithium-ion batteries and solar hydrothermal batteries is systematically reviewed, and their excellent electrochemical application potential is analyzed. At last, the future development of PVA based GPEs in this field is prospected.
