Liquid low-sodium siliscate forming-solution used for a storage battery, and a container formation method

Abstract

Present invention is related to a liquid low concentration sodium-containing silicate solution as the activation solution for lead-acid storage batteries and an internal activation method. Such an activation solution is prepared by mixing a silica gel containing 40˜60 wt % SiO2, the weight units of such a silica gel are 5-15, with 15-25 weight units of water. Adjusting the pH value of this mixture to 1-4 using inorganic acid and magnetizing the mixture in 1000-6000 Gauss magnetic field for 5-10 minutes, and finally obtains a liquid low concentration sodium-containing silicate solution with a viscosity less than 0.02 poise. Fill this activation solution into battery tank and use a charger to activate electrochemically. The operating temperature is room temperature and time is 30-50 hours. Using such an activation solution and procedures described above can avoid the releasing of acid smog and serious environmental pollution and healthy hazard for workers. Attributed to liquid state and good fluidity of the activation solution and not producing heat during activation, the battery as made can be activated within a short time and the rate performance can be improved to 25-30 C.
