In this report, we incorporate activated carbon (AC) onto aluminum substrate via doctor blade method to produce an all-solid-state supercapacitor. The electrochemical properties of the all-solid-state supercapacitor were characterized by cyclic voltammetry and electrochemical impedance spectroscopy. Galvanostatic charge/discharge tests also were carried out to exhibit stability of the AC-based supercapacitor. The impedance and charge/discharge curves of the all-solid-state supercapacitor showed good capacitive behavior after functionalized AC. The highest specific capacitance obtained for the AC-based supercapacitor was 106 F g⁻¹. About 160% of specific capacitance increased after functionalization of the AC, which indicated that modification of the AC by nitric acid was able to introduce functional groups on the AC and improve its electrochemical performances.

在本报告中，我们通过刮刀法将活性炭（AC）结合到铝基板上，以生产全固态超级电容器。通过循环伏安法和电化学阻抗谱表征了全固态超级电容器的电化学性能。还进行了恒电流充电/放电测试，以显示基于AC的超级电容器的稳定性。全固态超级电容器的阻抗和充电/放电曲线在功能化的交流电之后表现出良好的电容性能。对于基于AC的超级电容器，获得的最高比电容为106 F g ^-1。AC官能化后，约160％的比电容增加，这表明通过硝酸对AC进行修饰能够在AC上引入官能团并改善其电化学性能。
