Decoration of carbon cloth by manganese oxides for flexible asymmetric supercapacitors
Source abstract
Abstract
Abstract Here we describe the production of carbon cloth coated with MnO 2 nanosheets or MnOOH nanorods through a normal temperature reaction or a hydrothermal approach, respectively. Of note, the electrochemical performance of MnO 2 -coated carbon cloth was better (429.2 F g −1 ) than that of MnOOH-coated carbon cloth. When the MnO 2 -coated carbon cloth is introduced as the positive electrode and the Fe 2 O 3 -coated carbon cloth as the negative electrode, a flexible asymmetric supercapacitor was obtained with an energy density of 22.8 Wh kg −1 and a power density of 159.4 W kg −1 . Therefore, such a hierarchical MnO 2 -coated carbon cloth nanocomposite is a promising high-performance electrode for flexible supercapacitors.
