These porous carbons applied as electrode materials for supercapacitors exhibited an excellent capacitive behavior in basic, acid, and neutral aqueous electrolytes. The respective specific capacitances for LPC and BPC were 223 and 200 F g-1 at current density of 50 mA g-1, and 175 and 151 F g-1 at current density of 2.5 A g-1 in a 3 M KOH electrolyte. Moreover, the porous carbons had high area specific capacitance (up to 33.4 µF cm-2), superior cycling performance, and low resistance. This work demonstrates a promising preparation route for large-scale production of hierarchical porous carbons for high-performance supercapacitors.]]> Thu 20 Sep 2018 16:52:02 AEST ]]> Facile synthesis of graphene nanosheets from humic acid for supercapacitors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30947 2·g− 1) with large pore volume (2.987 cm3·g− 1), unique interconnected mesoporous structure and uniform oxygen-containing functional groups in layered graphene framework, which offer a favorable and efficient pathway for the electrolyte propagation and transportation. The electrodes of supercapacitors made from these graphene nanosheets exhibit a maximum specific capacitance of 272 F·g− 1 at the current density of 50 mA·g− 1 in aqueous electrolyte, and possess excellent rate capability, low resistance, superior cycling performance with over 96.5% initial capacitance retention after 8000 cycles. The corresponding supercapacitors deliver a desirable energy density of 6.47 Wh·kg− 1 at a powder density of 2250 W·kg− 1.
