H2SO4 Electrolyte — An Active Material in the Lead—Acid Cell 

H2SO4 Solutions Used as Electrolytes in the Battery Industry 

Purity of H2SO4 Used in Lead—Acid Batteries 

The lead—acid battery is a delicate electrochemical system in which the current generation electrochemical reactions involving lead compete with the electrochemical reactions of water decomposition (Fig. 2.1). A number of impurities exert strong effect on the above competition by accelerating the decomposition of water and, thus, may have a detrimental effect on battery performance. Therefore, the sulfuric acid solutions used for battery manufacture should have
