Se-doped graphene was prepared via supercritical fluid route using selenium dioxide and graphene oxide, and achieved a maximum specific capacitance of 581 F g−1 at 1 A g−1 in 1 M H2SO4. The full cell studies in redox electrolytes revealed an energy density of 23.3 Wh kg−1 in 0.01 M AV/1 M H2SO4 with 85% and 94% of capacitance retention and coulombic efficiency, respectively, over 50000 cycles.
