ABSTRACT In this study, binary (CB/MnO2) and ternary nanocomposites (CB/MnO2/PPy) include carbon black (CB) and manganese (IV) oxide (MnO2) and polypyrrole (PPy) were chemically synthesized and were characterized by many techniques such as : FTIR-ATR, Raman spectroscopy, SEM-EDX, TGA-DTA analysis, XRD, TEM and BET surface analysis. Electroactive materials were used as a symmetric supercapacitor device system and taken 3 methods (cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS)). CB/MnO2/PPy nanocomposite at [CB]o/[MnO2]o/[Py]o = 1:1:3 showed a highest specific capacitance of C sp = 273.2%F/g at a scan rate of 1 mV/s in 1 M H2SO4 solution. This nanocomposite combination supplies higher energy and power densities of supercapacitor device (E = 0.5513 Wh/kg and P = 91.556 W/kg at 6 mV/s). Equivalent circuit model of R s(C 1(R 1(C 2(R 2 W)))) was used to analyze circuit parameters. Furthermore, the symmetric device for CB/MnO2/PPy nanocomposite at [CB]o/[MnO2]o/[Py]o = 1:1:5 shows an excellent long cycle life with 92.20% of initial capacitance retention after 1000 cycles. CB/MnO2/PPy nanocomposite electrode can be a candidate for supercapacitor applications. GRAPHICAL ABSTRACT

摘要 在这项研究中，二元 (CB/MnO2) 和三元纳米复合材料 (CB/MnO2/PPy) 包括炭黑 (CB) 和锰 (IV) 氧化物 (MnO2) 和聚吡咯 (PPy) 是化学合成的，并通过多种技术进行表征如：FTIR-ATR、拉曼光谱、SEM-EDX、TGA-DTA分析、XRD、TEM和BET表面分析。电活性材料被用作对称超级电容器装置系统并采用3种方法（循环伏安法（CV）、恒电流充放电（GCD）和电化学阻抗谱（EIS））。[CB]o/[MnO2]o/[Py]o = 1:1:3 的 CB/MnO2/PPy 纳米复合材料在 1 mV/s 的扫描速率下显示出最高的比电容 C sp = 273.2%F/g在 1 M H2SO4 溶液中。这种纳米复合材料组合为超级电容器装置提供更高的能量和功率密度（E = 0.5513 Wh/kg 和 P = 91.556 W/kg，6 mV/s）。采用R s(C 1(R 1(C 2(R 2 W)))) 等效电路模型分析电路参数。此外，[CB]o/[MnO2]o/[Py]o = 1:1:5 的 CB/MnO2/PPy 纳米复合材料的对称器件显示出优异的长循环寿命，1000 次循环后初始电容保持率为 92.20%。CB/MnO2/PPy 纳米复合电极可以成为超级电容器应用的候选者。图形概要
