A lead-acid battery having thixotropic gel electrolyte comprising a blend of alkali metal polysilica and sulfuric acid. A method for producing a lead-acid battery having thixotropic gel electrolyte may be a continuous or an intermittent process. An aqueous colloidal dispersion may be produced by blending dry alkali metal polysilica with water and the gel electrolyte is provided by combining the aqueous collodial dispersion of alkali metal polysilica with liquid sulfuric acid.

A lead-acid battery having electrolytic-absorbent separator is formed in situ to produce sponge lead and lead dioxide active material. The method includes cooling the electrolyte to below room temperature, introducing a quantity of cooled electrolyte into the battery and charging the battery to a preselected degree. The battery is further filled with electrolyte to provide electrolyte saturated plates and separators and is further charged to a preselected degree defining a fully charged state.
