用聚合物水凝胶电解质浸渍的磺化聚丙烯隔膜用于双电层电容器（EDLC）。通过循环伏安法和充放电循环测试研究了聚合物水凝胶电解质双电层电容器的电化学性能，并与KOH水溶液电解质进行了比较。研究了KOH浓度和温度对双电层电容器电容的影响。结果发现，在宽的KOH浓度和温度范围内，具有聚合物水凝胶电解质的EDLC的电容高于具有KOH水溶液的EDLC的电容。(C)2004 Elsevier Ltd.保留所有权利。
Sulfonated polypropylene separators impregnated with the polymer hydrogel electrolyte were used in electric double layer capacitors (EDLCs). The electrochemical properties of the EDLC with the polymer hydrogel electrolyte were investigated by cyclic voltammetry and charge-discharge cycle tests and compared with a KOH aqueous electrolyte. Furthermore, effects of KOH concentration and temperature on capacitance of the EDLC were studied. As a result, it was found that the capacitance of the EDLC with the polymer hydrogel electrolyte was higher than that with a KOH aqueous solution in the wide range of KOH concentration and temperature.
