Activated carbon fiber paper with exceptional capacitive performance as a robust electrode for supercapacitors†
Abstract
Herein, a facile and available electrochemical activation approach has been developed to markedly boost the capacitive performance of carbon fiber paper (CFP). The activated CFP could deliver a significant areal capacitance of 1.56 F cm−2 at a high current density of 5 mA cm−2 with excellent rate capability and cycling performance.
