The influence of traces of impurities in the lead-acid battery electrolytes

Abstract

The authors describe a study of impurities in the electrolytes of lead-acid storage batteries for solar photovoltaic power systems. They concentrate on the determination of copper, cadmium, lead, silicate, phosphate, acetate, arsenate, chloride, formate, and nitrate in the lead-acid battery electrolytes after a known number of charging/discharges cycles. Different experimental techniques were used to analyze the various ionic species present in the battery electrolytic.<>
