Upcycling sawdust into sustainable binder-free nitrogen-doped carbon nanofiber electrodes for high energy density supercapacitors

DEDalia M. El-GendyHTHebat-Allah S. TohamyESEhab N. El Sawy

Key Points

  • The aim is to transform pinewood sawdust into nitrogen-doped carbon nanofibers for use in high-energy supercapacitors.
  • Converted pinewood sawdust waste into nitrogen-doped carbon nanofibers (N-CNFs).
  • Evaluated the capacitive performance of N-CNFs in supercapacitors.
  • Tested stability over 4000 charge-discharge cycles.
  • Achieved a capacitance of 1280 F g−1.
  • Demonstrated 100% stability over 4000 cycles.

Abstract

Pinewood sawdust waste was converted into nitrogen-doped carbon nanofibers for supercapacitors. The N-CNFs achieved a capacitance of 1280 F g −1 with 100% stability over 4000 cycles, offering a high-energy, sustainable storage solution for EVs.
