Hello. Help me please. We have done a first charge of the vanadium electrolyte, we has a vanadium 4+ in 2.5 M H2SO4 and 6M HCl as catholyte and anolite. We charged catholyte for the 5+ and anolyte for 3+, but jn the graph current against time we have peak in potentiostatic condition. In the electrolyte without HCl we did not have this peak. Wath is this peak? As far as I know the current should decrease exponentially.
