<p>The invention relates to a liquid low-sodium silicate electrolyte used for a storage battery and manufactured by magnetization process, and the usage thereof. The process includes the steps of adding 5-15 parts by weight of silica sol containing 40-60wt% SiO2 into 15-25 parts by weight of water while agitating to obtain a mixture, the concentration of which is measured by Baume densimeter to be 0.65-0.85% Be', then adding an inorganic acid into the mixture until the PH being 1-4, and placing the mixture into magnetic field having 1000-6000 gauss for 5-10 minutes, then taking it out of the magnetic field and agitating it until its viscosity measured by a rotary viscometer being less than 0.02mPas, and thus obtaining the liquid low-sodium silicate electrolyte. The electrolyte is used as a electrolyte or a forming solution in an ordinary battery or a special battery. A storage battery prepared by the electrolyte has a specific energy of 53W/kg or more and the service life of the storage battery increases from 350 to 400 times or more. The storage battery has resistance to low and high temperature and operates normally at the temperature of -50°C∩+60°C.</p> |
