Scholarcy highlights

  • Three-dimensional kenaf stem-derived porous carbon is considered to be a promising low-cost supporting material for application in energy storage devices
  • A simple and industry-scalable approach to prepare the hybrid of nanostructured MnO2 and 3D-PC has been developed. Such porous structures of the 3D-PC provided a conductive network to enhance the charge transport and mass transfer in the electrochemical process and achieved a large MnO2 mass loading capacity of 11.5 mg/cm2, which resulted in a high areal capacitance of 2.77 F/cm2 at a scan rate of 1 mV/s
  • A specific capacitance of 416 F/g was obtained based on the mass loading of 2.52 mg/cm2 at scan rate of 1 mV/s
  • This research demonstrated that the 3D-porous carbon was a good potential supporting material in energy conversion and storage devices
