A Study on the Valve Regulated Lead-Acid Battery using Sulfuric Acid Gel Electrolyte for New Generation Substitution Energy

The capacity and long life of gel electrolyte batteries is connected with gas recombination producting PbO2 and Pb electrode. We prepared with sulfuric acid gel electrolyte to know gel characteristics per density to assemble valve regulated lead-acid (VRLA) batteries. We studied on actions of sulphuric acid gel electrolyte by measuring electrolyte dispersion using Brewster-angle microscope (BAM), charge-discharge cycle, and electrode structure using scanning election microscope (SEM). Sulphuric acid density 1.210 showed excellent gel dispersion in sol condition, electrode condition after fifty cycles in this study.
