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 cont...

Low-sodium silicate liquid electrolyte is manufactured by mixing 15-25 pts. wt. water and 5-15 pts. wt. silica sol (containing 40-60 wt.% SiO 2) to a Baume density of 0.65-0.85 % [deg]Be; addition of an inorganic acid to adjust the pH to 1-4; magnetization...
