摘要： The invention relates to a liquid low-sodium silicate forming-solution used for a storage battery and a container formation method. The forming solution is prepared by mixing 5-15 parts by weight of silica sol containing 40-60wt% SiO2 with 15-25 parts by weight of water, then adding an inorganic acid into the mixture until the PH being 1-4, and magnetizing the mixture in a magnetic field having 1000-6000 gauss for 5-10 minutes to obtain a liquid low-sodium silicate forming-solution with its viscosity being less than 0.02mPas. The liquid low-sodium silicate forming-solution is poured into a battery container. Sequentially, the battery is formed by applying power to the battery at the room temperature for 30∼50 hours. By using the liquid low-sodium silicate forming-solution, a great amount of acid mist is thoroughly keeped from escaping in the period of formation during manufacturing the battery, thus to prevent environment from being polluted and an operator from being harmed. The battery won't generate heat at the time that it is formed, and the battery is sufficiently formed in the shortest time, because the forming solution is a fluid state with good fluidity. The storage battery thus obtained has 25C ∼ 30C discharge capacity.

摘要： 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.
