Abstract

The invention discloses a container-formed gelled electrolyte and a preparation method thereof. The container-formed gelled electrolyte is characterized by containing effective chemical components including, by weight percentage, 29.4%-36.6% of sulfuric acid, 3.5%-4.8% of silicon dioxide, 0.05%-0.50% of potassium sulfate, 0.8%-1.8% of sodium sulfate, 1.0%-6.0% of thermal conduction materials, 0.001%-0.020% of polyacrylamide, 0.005%-0.200% of sodium molybdate and 50.080%-65.244% of water. The container-formed gelled electrolyte has the advantages of integrating the physical and chemical properties of total-sodium silicate gelled electrolytes and total-fumed silica amorphous structured gels, and effectively solving the problem of low heat dissipating speed of gel batteries.

Description

technical field [0001] The invention relates to the field of electrolytes, in particular to internalization into PVC-SIO 2 Electrolyte formula and preparation method of colloidal storage battery. Background technique [0002] Relative AGM separator gel battery, PVC-SIO 2 Separator gel batteries are called full gel batteries (hereinafter referred to as gel batteries). There are two technical difficulties in the production of gel batteries: [0003] One is that the viscosity of the electrolyte is high and it is difficult to fill the glue. The silicon dioxide content in the colloidal electrolyte is high, and the viscosity of the electrolyte is extremely high. The electrolyte is poured into the battery and reacts violently with the alkaline raw plate. The capacity, service life and other performance of the battery; [0004] The second is that the temperature of the battery is high during the glue filling and formation process, the heat dissipation is slow, and it is difficul...
