Title: | Flexible Carbon Cloth Supercapacitors with High Power and Energy Densities | Authors: | Xu, Jing Li, Changli Yu, Siyu Wang , Zilong Pritzel, Christian Jiang , Xin YANG, Nianjun |
Issue Date: | 2023 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | Energy Technology, 11 (8), (Art N° 2300214) | Abstract: | Commercially available carbon cloths (CCs) are promising candidates to construct flexible and wearable electronics. Herein, post-treated CCs are employed to construct flexible supercapacitors (SCs). CCs are first activated in KOH solution and subsequently thermally annealed, resulting in their unique porous microstructure and a wide potential window up to 2.2 V. Using these binder- and current-collector-free CCs as the capacitor electrodes, a high-performance and flexible electrical double-layer capacitor is constructed. In 1 m KOH aqueous solution, its specific capacitance of as high as 1 967.0 mF cm(-2) is obtained at a current density of 30 mA cm(-2). Moreover, it exhibits excellent capacitance retention and delivers both high energy density (e.g., 93.38 W h kg(-1) at a power density of 3 890 W kg(-1)) and high power density (e.g., 12 850 W kg(-1) at an energy density of 12 W h kg(-1)). Such binder-free, easy-assembling, scalable flexible SCs are thus promising for miniaturized electronic industries in the future. | Notes: | Xu, J (corresponding author), Guizhou Univ, Coll Mat & Met, Guiyang 550025, Peoples R China.; Jiang, X (corresponding author), Univ Siegen, Inst Mat Engn, D-57076 Siegen, Germany.; Yang, NJ (corresponding author), Hasselt Univ, Dept Chem, B-3590 Diepenbeek, Belgium.; Yang, NJ (corresponding author), Hasselt Univ, IMO IMOMEC, B-3590 Diepenbeek, Belgium. jxu8@gzu.edu.cn; xin.jiang@uni-siegen.de; nianjun.yang@uhasselt.be |
