摘要: 为了制备出适合有机电解液的多孔碳材料，提高其电化学性能，本文利用高分子作为碳源，葡萄糖作为诱导剂，通过KOH活化，制备出3D交联多孔碳材料。通过XRD、拉曼、XPS、SEM等方法对其进行表征。组装成超级电容器，通过电化学测试表明，在1 A g−1下具有较高的比电容。在20 A g−1的电流密度下循环10,000次，还有66.2%的电容保持率。此外，在10 A g−1的高电流密度下，具有较小的电容衰减。
Abstract: In order to prepare porous carbon material suitable for organic electrolyte and improve its elec-trochemical performance, this paper used polymer as carbon source and glucose as inducer, and prepared 3D cross-linked porous carbon material through KOH activation. It was characterized by XRD, Raman, XPS and SEM. The supercapacitor was assembled and the electrochemical test showed that it had a high specific capacitance at 1 A g−1. There is still capacitance retention of 66.2% at a current density of 20 A g−1 for 10,000 cycles. Furthermore at a high current density of 10 A g−1, there is only a small capacitance attenuation.
