Facile Synthesis and Performance of Reduced Graphene Oxide/Cobalt Oxide Composite for Supercapacitor

Abstract:

A series of reduced graphene oxide/cobalt oxide composites (Co₃O₄/rGO)were fabricated via a chemical precipitation approach and subsequent calcination in Ar atmosphere. Experimental results show that Co₃O₄/rGO composite with 86 wt% of Co₃O₄ loading exhibits the optimum specific capacitance of 240 F g^-1 in 6.0 M KOH electrolyte at the current density of 0.8 A g^-1, excellent quick charge-discharge performance and outstanding cyclic stability with 2.3% of its specific capacitance increase after 2400 cycles at the current density of 8 A g^-1 in GCD test, exhibiting significant potential of Co₃O₄ /rGO composite in the application of supercapacitors.
