The Effect of Phosphoric Acid on the Positive Electrode in the Lead ...
The effect of phosphoric acid on the positive electrode reaction in a lead--acid battery is studied by cyclic voltammetry. It is proposed that phosphate reversibly adsorbs on the PbO/sub 2/ during charge and modifies the crystal growth of PbO/sub 2/ on the lead grid. The form of PbO/sub 2/ produced in the presence of phosphate is not easily reduced to lead sulfate and, therefore, the …
