ALKALI METAL POLYSILICA GEL ELECTROLYTE LEAD-ACID BATTERY AND METHOD FOR MAKING THE SAME

摘要

A method for producing a lead-acid battery having a thixotropic gel electrolyte, comprising combining an aqueous colloidal dispersion of alkali metal polysilica with sulfuric acid while introducing the combination into a lead-acid battery precursor. A lead-acid battery comprising a battery case, positive and negative metal plates spaced one from another within said case and a thixotropic gel electrolyte within said case and providing electrolytic connection between said positive and negative plates, comprising sodium polysilica, sulfuric acid and water.
