To investigate the stability of graphite felt (GF) for all-vanadium redox flow battery(VRB)
the electrochemical performance
mass change and morphology of GF were studied by cyclic voltammetry (CV)
mass analysis
SEM
and charge-discharge test. The results showed that the GF was oxidized and absorbed the electrolyte as result in causing mass reduction
while the electrochemical performance of the GF basically kept stable. The Coulomb efficiency and energy efficiency respectively were about 96% and 80%.
