摘　　要：聚合物电解质作为固态超级电容器的重要组成部分成为了研究热点。本论文利用天然高分子大豆分离蛋白自身的乳化性,与EMPA交联制备了具有多孔结构的聚合物电解质基体材料,结合硫酸锂电解质,构建了大豆分离蛋白基聚合物电解质,并采用活性炭电极组装了双电层电容器,其单电极质量比电容在1.0 A/g的电流密度下能够达到113.59 F/g。Polymer electrolyte,as a key component of solid-state supercapacitor,has been a research hotspot.The porous polymer electrolyte matrix was prepared by the natural soybean protein isolate crosslinked with EMPA as a crosslinked,which took advantage of the emulsification of soybean protein isolate.The polymer electrolyte was constructed with the porous matrix and Li2SO4 electrolyte,after which the electrical double-layer capacitor was fabricated with activated carbon electrodes.The single electrode gravimetric capacitance could reach 113.59 F/g at a current density of 1.0 A/g.
