Abstract:The influence of europium ion in sulfuric acid solution on the electrochemical performance of the lead electrode was studied by linear sweep voltammetry,cyclic voltammetry,chronoptentiometry and AC impedance methods.The experimental results showed that the addition of europium ion could effectively improve the reversibility of the transfer reaction of Pb/PbSO4 and the overpotential of hydrogen evolution reaction on the electrode in the existence of europium ion in sulfuric acid solution was higher than that...
