Chlorine-doped carbonated cobalt hydroxide for supercapacitors with enormously high pseudocapacitive performance and energy density

High yield, industrial acceptable hydrothermal synthesis method is developed to synthesis unique NWs of Co(CO3)0.35Cl0.20(OH)1.10 and used as a high performance electrode for supercapacitors, which exhibits remarkable capacitance (9893.75 F/g) and energy density (220 W h/kg) along with long cyclic stability of 10,000 cycles; considered as promising material for high energy storage devices.287
