High electrochemical performance in asymmetric supercapacitors using MWCNT/nickel sulfide composite and graphene nanoplatelets as electrodes
Abstract
A high-performance asymmetric supercapacitor was fabricated using MWCNTs/NiS composite and GNPs as electrodes, exhibiting high specific capacitance of ∼181 F g −1 at 1 A g −1 current density and excellent cyclic stability with 92% retention after 1000 cycles at 2 A g −1 current density.The electrochemical performance of asymmetric supercapacitors (ASCs) using MWCNT/NiS and graphene nanoplatelets as the positive and negative electrode, respectively, are reported. Nickel sulfide nanoparticles can be decorated on multiwall carbon nanotubes using a hydrothermal synthesis process, with graphene nanoplatelets obtained via a chemical route. The fabricated ACSs were operated over a potential window of 1.4 V with a specific capacitance of 181 F g −1 observed at 1 A g −1 . The ASCs were cycled at 2 A g −1 showing 92% retention of initial capacitance after 1000 cycles.
