介绍了一种简单、低成本的柔性固体超级电容器石墨/聚苯胺复合电极的制备方法。所制备的混合电极是化学稳定的，在0.5 mA cm-2的电流密度下显示出32.3 Ω sq-1的低薄层电阻和355.6 mF cm-2的高面积电容。由两个拉伸石墨/聚苯胺网络混合电极组装的纸基对称超级电容器在4.57 mA cm-3的电流密度下表现出3.55 F cm-3的体积电容，并且在0.054 W cm-3的功率密度下表现出约0.32 mWh cm-3的能量密度（归一化到固态装置的整个体积）。这些令人鼓舞的结果显示了它们在柔性和固态储能系统中的巨大潜力。
A simple and low-cost method involving pencil-drawing and electrodeposition is introduced to fabricate graphite/polyaniline hybrid electrodes on paper for flexible solid-state supercapacitors. The as-prepared hybrid electrodes, which are chemically stable, show a low sheet resistance of 32.3 Ω sq−1and a high areal capacitance of 355.6 mF cm−2at a current density of 0.5 mA cm−2. The paper-based symmetric supercapacitors assembled by two pencil-drawing graphite/polyaniline networks hybrid electrodes exhibit a volume capacitance of 3.55 F cm−3at a current density of 4.57 mA cm−3, and an energy density of about 0.32 mWh cm−3at a power density of 0.054 W cm−3normalized to the whole volume of the solid-state device. These encouraging results show their great potential in flexible and solid-state energy storage systems.
