Abstract

Ultrathin nanoflakes of Ni(OH)₂ were synthesized onto multi-walled carbon nanotubes (MWCNTs) by simple low cost chemically precipitation method for high performance electrochemical supercapacitor applications. The synthesized ultrathin Ni(OH)₂ exhibit high specific capacitance of 1735 Fg^-1 at a scan rate of 5 mV s^-1 with excellent rate capability. This high performance of Ni(OH)₂ nanoflakes was attributed to its complete accessibility to the electrolyte and maximum utilization of metal hydroxides. Findings of this work suggest that synthesized electrodes offer low-cost and scalable solution for high-performance energy storage devices.
