Abstract

The invention relates to an electrolyte for a lead-acid accumulator, in particular to a colloidal electrolyte and a preparation method thereof. The invention adopts the following technical scheme that the colloidal electrolyte is prepared from the following components in percentage by weight: 0.3 to 1.0 percent of silicon dioxide, 0.05 to 0.25 percent of cobaltous sulphate, 0.5 to 1.0 percent of sodium sulphide, 0.05 to 0.5 percent of stannous sulfate, 92 to 95 percent of dilute sulphuric acid of which the density is 1.330 to 1.400g / cm<3> and the balance of water of which the pH value is 7 to 9.

Description

technical field [0001] The invention relates to an electrolyte used in a lead-acid storage battery, in particular to a colloidal electrolyte used in a lead-acid storage battery. Background technique [0002] At present, the common batteries used in the prior art are still mainly lead-acid batteries. The electrolyte of lead-acid batteries is prepared from dilute sulfuric acid and deionized water. The preparation method is relatively simple and the cost is low. Therefore, this battery Still widely used in all walks of life. [0003] For example, a high-conductivity sodium salt electrolyte disclosed in Chinese Patent No. 200710090477.3 is made of the following components by weight: sodium silicate and / or sodium fluorosilicate, 1.95~2.20% by weight; cobalt sulfate And / or zinc sulfate, 0.0012~0.0062‰ by weight; sodium phosphate and / or slightly calcium acid, 0.0051~0.014‰ by weight; density 1.260~1.400g / cm 3 dilute sulfuric acid, 90.80~91.30% by weight; inhibitor, 0.0035~0.024...
