Abstract

Abstract : The heteroatom-doped graphite felt electrode with prominent hydrophilicity presents excellent electroactivity towards V 2+ /V 3+ and VO 2+ /VO2 +, and dramatically extends the energy efficiency of vanadium redox flow batteries towards 1000 cycles with 0.003% reduction per cycle. Abstract : The phosphorus and fluorine codoped graphite felt electrodes with prominent hydrophilicity present excellent electroactivity towards V 2+ /V 3+ and VO 2+ /VO2 +, elevate the discharging ability up to 250 mA cm −2 and dramatically extend the energy efficiency of vanadium redox flow batteries towards 1000 cycles with 0.003% reduction per cycle.
