FIELD: electrical engineering; liquid silicate electrolyte and its use for storage batteries.;SUBSTANCE: proposed electrolyte preparation process includes addition of silicic acid sol in the amount of 5 - 15 parts by weight containing silicon dioxide (SiO2) in the amount of 40 - 60 mass percent to water taken in the amount of 15 - 20 parts by weigh while stirring mixture until its concentration, as measured by Baume hydrometer, ranges between 0.65 and 0.85 Baume degrees; addition of inorganic acid to mixture obtained in the process until its pH ranges between 1 and 4; placement of mixture obtained into magnetic field whose flux density ranges between 0.1 and 0.6 T (between 1000 and 6000 G) for 5 to 10 minutes; and stirring of magnetized mixture upon its withdrawal from magnetic field until its dynamic viscosity becomes lower than 0.02 mP-s to obtain low-sodium-content liquid electrolyte. Storage battery using proposed electrolyte is characterized in specific power capacity of 53 W and higher, its service life is increased from 350 to 400 or more charge-discharge cycles; such battery will operate normally at low and high temperatures, its operating temperature range being between -50 and +60 C.;EFFECT: enhanced capacity and service life, enlarged operating temperature range of battery using proposed electrolyte.;7 cl, 2 dwg, 2 ex
