Abstract
The present invention provides a lead-acid accumulator used colloidal electrolyte which belongs to the chemical electric power source field and relates to a colloidal electrolyte that can be used for the accumulator of the electric car. The colloidal electrolyte is mainly mixed with sulfuric acid, gelinite, glycerine and deionized water for a certain ratio, the gelinite is mixed with sodium silicate and sulfuric acid solution with a certain volumetric ratio and is prepared after dewatering. The colloidal electrolyte prepared with the method is used for bottling the accumulator and the colloid accumulator with higher capability can be generated, the initial capacity is above 96and the uniformity of the initial floating charging voltage is excellent. Besides the generated colloidal electrolyte has the advantages of not easy cracking, not easy hydrating, excellent thixotropy, facilitating the bottling, convenient operation and low producing cost. The accumulator bottled by the electrolyte has stable electrically discharging property and excellent starting performance. The deep-discharge cycling service-life is increased for about one time comparing with the homogeneous liquid electrolyte accumulator.
Description
One, technical field
The invention belongs to field of chemical power source, relate to a kind of colloidal electrolyte that can be used for electromobile battery.
Two, background technology
At present, the ubiquitous defective of electric motor car colloid storage battery of market sale is: 1, owing to formed with SiO by colloid
2For the influence of the stable tridimensional network timeliness of skeleton with there is the inhomogenous problem of oxygen channel design quality, cause colloid storage battery in use, exist internal resistance big, the low and relatively poor phenomenon of initial stage monomer float charge voltage homogeneity of initial capacity.2, colloid quality less stable is easy to generate be full of cracks or aquation, has the seepage phenomenon of acid.
Three, summary of the invention
The object of the present invention is to provide a kind of sealed type lead acid battery colloidal electrolyte formula and preparation method thereof.
Colloidal electrolyte is mixed by sulfuric acid, gelinite, glycerol, phosphoric acid, anhydrous sodium sulphate, EDTAP dipotassium ethylene diamine tetraacetate, stannous sulfate, anhydrous magnesium sulfate and deionized water, their weight is respectively 40～48%, 12～18%, 0.8～2.5%, 0.5～2.0%, 1.3～2.5%, 0.02～0.8%, 0.1～0.8%, 0.5～1.0% of preparation total weight, and surplus is a deionized water.Gelinite is that 1.48～1.52 sulfuric acid solution mixes through reaction by volumetric ratio and generates gel at 9: 1 by the sodium silicate solution of content 8～10% and density, use then in the deionized water flush away gel most of in ion, after dehydration gelinite is standby.
After the colloidal electrolyte of making is used to pour into storage battery, can produce the higher colloid storage battery of capacity, initial capacity is more than 96%, and initial stage float charge voltage homogeneity is good.And the colloidal electrolyte that generates is difficult for be full of cracks, is difficult for aquation, and good thixotropy is arranged, and is convenient to pour into easy to operate, and production cost is low.With the storage battery of this electrolyte perfusion, discharge performance is stable, and starting performance is good.About deep discharge cycle life is compared with similar liquid electrolyte battery and is doubled.
Four, embodiment
At first prepare gelinite: it is 9.2% solution that commercially available sodium metasilicate and deionized water are mixed with sodium metasilicate content; Storage battery is mixed with the sulfuric acid solution that density is 1.48-1.52 with sulfuric acid and deionized water; Make gel with sulfuric acid solution by volumetric ratio 9: 1 adding reactor with sodium metasilicate is molten.With the most of sodium ion in the deionized water flush away gel, it is standby to get gelinite after the dehydration.
Example 1, getting sulfuric acid 40%, gelinite 12%, glycerol 0.8%, phosphoric acid 0.5%, anhydrous sodium sulfate 1.3%, EDTAP dipotassium ethylene diamine tetraacetate 0.02%, stannous sulfate 0.1%, anhydrous magnesium sulfate 0.5%, the surplus of making the colloidal electrolyte total weight respectively is 44.78% deionized water, promptly gets colloidal electrolyte after mixing.Vacuum available liquid filler injecting accumulator.
Example 2, getting sulfuric acid 44%, gelinite 15%, glycerol 1.2%, phosphatase 11 .0%, anhydrous sodium sulfate 2.0%, EDTAP dipotassium ethylene diamine tetraacetate 0.35%, stannous sulfate 0.5%, anhydrous magnesium sulfate 0.8%, the surplus of making the colloidal electrolyte total weight respectively is 35.15% deionized water, promptly gets colloidal electrolyte after mixing.Vacuum available liquid filler injecting accumulator.
Example 3, getting sulfuric acid 48%, gelinite 18%, glycerol 2.5%, phosphoric acid 2.0%, anhydrous sodium sulfate 2.5%, EDTAP dipotassium ethylene diamine tetraacetate 0.8%, stannous sulfate 0.8%, anhydrous magnesium sulfate 1.0%, the surplus of making the colloidal electrolyte total weight respectively is 24.40% deionized water, promptly gets colloidal electrolyte after mixing.Vacuum available liquid filler injecting accumulator.
