Liquid low-sodium silicate electrolyte used for a storage battery and manufactured by magentization process, and the usage thereof

摘要

A liquid low concentration sodium-containing silicate solution as electrolyte for lead-acid storage batteries and its applications, is prepared by mixing a silica gel containing 40~60 wt % SiO2, the weight units of such a silica gel are 5~15; add 15-25 weight units water and stir until the concentration of the mixture is 0.65~0.85 0Be' measured by a Baum densimeter, adjusting the pH value of this mixture to 1-4 using inorganic acid and magnetizing the mixture under 1000-6000 Gauss magnetic field for 5-10 minutes, stir the magnetized mixture until the viscosity of the mixture is less than 0.02 poise and finally obtain a liquid low concentration sodium-containing silicate solution. The electrolyte can be used as electrolyte or activation solution for common or special lead-acid storage batteries.
