What is Acid Stratification? Acid stratification refers to the uneven distribution of the electrolyte solution within flooded lead-acid batteries. In a properly functioning battery, the electrolyte—a mixture of sulfuric acid and water—remains homogenous.However, stratification causes a higher concentration of sulfuric acid to settle at the bottom, while the upper regions

As low-cost and safe aqueous battery systems, lead-acid batteries have carved out a dominant position for a long time since 1859 and still occupy more than half of the global battery market [3, 4]. However, traditional lead-acid batteries usually suffer from low energy density, limited lifespan, and toxicity of lead [5, 6].
Principles of lead-acid battery. Lead-acid batteries use a lead dioxide (PbO 2) positive electrode, a lead (Pb) negative electrode, and dilute sulfuric acid (H 2SO 4) electrolyte (with a specific gravity of about 1.30 and a concentration of about 40%). When the battery discharges, the positive and negative electrodes turn into lead sulfate (PbSO
concentration of sulphuric acid was 35wt%. This concentration of sulphuric acid was used in the experiments except the conductivity measurements where the concentration was 4wt% due to the restriction of measuring range of instrument. To decrease the dilution heat, the sulphuric acid solution was pre-cooled to 0°C before mixing. 2.3 Methods
