Vanadium Redox

A novel method for preparing nitrogen-doped graphite felts as positive electrodes in vanadium redox flow batteries was developed and studied. These materials were synthesized by directly coating a thin polypyrrole layer on the graphite felt surface followed by subsequent carbonization in the presence of Co (NGF-Co).

Vanadium Redox

The effects of impurity, temperature, concentration of vanadium and sulphuric acid on the stability of electrolyte in vanadium redox flow batteries are studied. It is found that the sediment at positive electrodes is V2O5﹒1.6H2O , and the sediment at negative electrodes is V2(SO4)3﹒10H2O. Although impurities influence the stability of vanadium electrolyte to some extent, the matching relationship between the vanadium and H2SO4 concentration is more important . To avoid the sensitivity of vanadium electrolyte to impurities, the concentration of H2SO4 should be raised to a certain extent to confirm the stability of positive electrolyte. At the same time, a moderate vanadium concentration should be employed to assure the stability of negative electrolyte. From the viewpoint of increased stability , the prefered vanadium electrolyte composition is 1.5-1.6 M vanadium in 4-5M H2SO4 medium at temperature above -10°C besides the electrolyte with relatively high purity.
