Surface activated commercial carbon cloth as superior electrodes for symmetric supercapacitors
Commercial carbon fiber (T300) cloth as the original material is surface-treated by a two-step approach, lastly becoming a high-performance electrode. This kind of electrode has a high specific capacitance (42.2 F g −1 ), which is nearly a hundred times that of the original carbon cloth. After fabricating these electrodes into a symmetric supercapacitor device, it provides a high specific energy of 4.64 W h kg −1 at a specific power of 10 W kg −1 . Furthermore, the device showed long cycling
stability (it keeps 92% capacitance retention after 1000 cycles), good rate capability, and low internal resistance. This work is expected to provide guidance for the research of structural supercapacitors based on commercial carbon cloth.
We investigate the structural, optoelectronic, and thermoelectric properties of halide double perovskite X2GeSnI6 (X = Rb, Cs) compounds employing the full potential linearized augmented plane…
The research was done on the creation and use of bi-metal sulfide thin film, Nd2S3:Ni9S8. 41 nm-sized crystallites with 80% crystallinity were found in the material. The evaluated optical…
