Abstract
The invention discloses a power type lead-acid storage battery colloidal electrolyte and relates to storage batteries. Currently, the lead-acid storage batteries at home generally utilize dilute sulfuric acid as electrolyte, the dilute sulfuric acid is adhered on an AGM clapboard by gravity to generate delamination, the sulfuric acid concentration on the lower part of the storage battery polar plate is over high, the anode PbSO4 cannot be completely converted into PbO2 during the charging process, the current on the lower half part of the polar plate away from the pole lug of the polar plate is small to be insufficiently charged to cause sulfuric acid salinization, so that the service life of the storage battery is shortened. The power type lead-acid storage battery colloidal electrolyte is characterized in that the colloidal electrolyte further comprises a thickener and a flocculant, the content of sulfuric acid is 30-50 wt%, the content of sodium sulfate is 0.50-2 wt%, the content of nanometer silicon dioxide is 5-15 wt%, the content of polyacrylamide is 0.1-0.5 wt%, and the balance of deionized water. The power type lead-acid storage battery colloidal electrolyte disclosed by the invention has the beneficial effects of effectively reducing the delamination of the sulfuric acid and prolonging the service life.
Description
Technical field
The present invention relates to storage battery, is a kind of power lead acid battery colloidal electrolyte more specifically.
Background technology
At present, domestic lead acid accumulator adopts dilute sulfuric acid to do electrolyte more, produces layering but gravity causes dilute sulfuric acid to be attached on the AGM dividing plate, and accumulator plate bottom sulfuric acid density is too high, during charging, and anodal PbSO
4Can not change into PbO fully
2, cause pole plate the latter half active material utilization low, pole plate top and the bottom CURRENT DISTRIBUTION is inhomogeneous, and is little away from pole plate the latter half electric current of pole plate lug, and charging owes to fill, and causes sulfation, and the life of storage battery shortens.
Summary of the invention
The purpose of this invention is to provide a kind of power lead acid battery colloidal electrolyte, can overcome the deficiency of sulfuric acid stratification, have the advantages that effectively to reduce sulfuric acid stratification, to increase the service life.
The present invention realizes in the following way: a kind of power lead acid battery colloidal electrolyte, contain deionized water, sulfuric acid, nanometer grade silica, it is characterized in that colloidal electrolyte also contains thickener and flocculant, wherein the content of sulfuric acid is 30～50 (weight) %, the content of sodium sulphate is 0.50～2 (weight) %, nanometer grade silica content is 5～15 (weight) %, and the polyacrylamide amine content is 0.1～0.5 (weight) %, and all the other are deionized water.During operation, with 5～15 (weight) % nanometer grade silica as gel, mix with the sulfuric acid of 45% concentration of 0.50～2 (weight) %, 50 ℃ of lower stirrings 2～8 hours of constant temperature, then the polyacrylamide of 0.1～0.5 (weight) % that acicular nano crystal whisker or acicular nanometer fento is made as the sodium sulphate of flocculant (flow ability modifying agent) and 0.50～2 (weight) % of crystal as thickener (gel reinforcing agent) disperse join before in the mixed solution under 50 ℃, stir 4～8 hours to room temperature, at last ionized water is added in the mixed solution, regulate mixed liquor to 100 (weight) %, can obtain this colloidal electrolyte.
The invention has the beneficial effects as follows: a kind of power lead acid battery colloidal electrolyte of the present invention has the advantage that can effectively reduce sulfuric acid stratification, increase the service life.
Embodiment
During operation, with 5～15 (weight) % nanometer grade silica as gel, mix with the sulfuric acid of 45% concentration of 0.50～2 (weight) % that has prepared, keep stirring 2～8 hours with mixer under 50 ℃ of constant temperature, then the polyacrylamide of 0.1～0.5 (weight) % that acicular nano crystal whisker or acicular nanometer fento is made as the sodium sulphate of flocculant (flow ability modifying agent) and 0.50～2 (weight) % of crystal as thickener (gel reinforcing agent) disperse join before in the mixed solution under 50 ℃ of the constant temperature, stir 4～8 hours to room temperature with mixer, at last ionized water is added in the mixed solution, regulate mixed liquor to 100 (weight) %, can obtain this colloidal electrolyte.
Claims (2)
1. a power lead acid battery colloidal electrolyte contains deionized water, sulfuric acid, nanometer grade silica, it is characterized in that colloidal electrolyte also contains thickener and flocculant.
2. a kind of power lead acid battery colloidal electrolyte as claimed in claim 1, wherein the content of sulfuric acid is 30～50 (weight) %, the content of sodium sulphate is 0.50～2 (weight) %, nanometer grade silica content is 5～15 (weight) %, the polyacrylamide amine content is 0.1～0.5 (weight) %, and all the other are deionized water.
