摘要: 可生物降解的凝胶电解质超级电容器是一种绿色的能源储存装置。制备了戊二醛交联明胶-NaCl 凝胶电解质(CGPE),并与聚吡咯不锈钢电极组装成超级电容器。通过FTIR、SEM 表征了CGPE 的结构和形貌,电化学工作站测试了CGPE 的电导率和超级电容器的比电容值。结果表明:CGPE 有均匀分布的纳米孔洞结构,在室温下,CGPE 的离子电导率为5. 24 × 10-2 S/cm,组装的超级电容器比电容值为45.8 F/g。可生物降解的凝胶电解将为植入能源装置提供可能。

Abstract: Biodegradable gel electrolyte supercapacitors are green energy storage devices. The crosslinked gelatin-NaCl gel electrolyte(CGPE)was synthesized,and with polypyrrole stainless steel electrode,the supercapacitors were fabricated. The structure and morphology of CGPE were characterized with FTIR and SEM. The ionic conductivity of CGPE and the specific capacitance of supercapacitor were determined with electrochemical workstation. The results showed that the nanometer pore evenly distributed in the CGPE. the ionic conductivity of CGPE was 5. 24×10-2 S/cm at room temperature,the specific capacitance of supercapacitor was 45. 8 F/g . Biodegradable gel electrolyte provides possibility for implantation of energy devices.

Key words: gel electrolytes, gelatin, supercapacitor, ionic conductivity, cross-linked
