Description
Technical field
The electrolyte that the present invention relates to use in the storage battery is specifically related to a kind of colloidal electrolyte.
Background technology
Colloid storage battery be with colloid as electrolyte, be a kind of special storage battery.Colloid storage battery mainly adopts valve-control sealed technology, is a kind of of enclosed accumulator.The colloidal electrolyte that is gel state does not flow in storage battery, thereby not leakiness acid.The colloidal electrolyte helps keeping dividing plate antianode grid and keeps enough pressure in the battery, can suppress effectively that anode active material comes off and the growth of lead dendritic crystal and infiltration, extending battery life.Colloidal electrolyte is in battery charge and discharge process, can change by recurring structure owing to the variation of electrolyte acid concentration, in discharge process, reduce owing to the electrolyte acid concentration, micro-crack appears in gel rubber system, the oxygen that generates for positive pole moves and the compound passage that provides to negative pole, obviously will lack the loss of water in the battery cyclic process, the situation that battery lost efficacy because of dry dehydration has obtained tangible improvement.Desirable its life-span of colloid storage battery of structure, what have more reached more than 10 years, was more than the twice in common valve control storage battery life-span usually more than 5 years.But the sulfuric acid electrolyte common owing to the colloidal electrolyte ratio of viscosities of colloid storage battery use is a lot of greatly, and this has brought acid test for filling acid technology of battery; In addition, if the colloid insufficient strength may cause the colloid fragmentation when battery is subjected to sharp pounding or collision, battery performance is greatly descended.Though colloidal electrolyte has certain thixotropy, even under the high-speed stirred condition, its viscosity is still much bigger than bright sulfur acid electrolyte, and it is slow not only to irritate sour speed, and battery is difficult for filling, and in most cases needs the back to mend glue.Full-bodied colloidal electrolyte is difficult to evenly flow into inside battery utmost point group everywhere in the encapsulating process, causes battery capacity inconsistent.Because the flowability of colloidal electrolyte is poor, permeability also decreases, and colloidal electrolyte very likely causes dividing plate or pole plate to occur doing to the poor permeability of dividing plate, pole plate, has a strong impact on battery performance.No matter existing colloidal electrolyte is nano silicon system or Ludox system, and its encapsulating flowability is all very poor, and battery serviceability and life-span are all far below expection.
Summary of the invention
The present invention will solve the encapsulating difficulty that has Colliod electrolyte for accumulator now and cause because of the mobile difference of encapsulating, the problem that encapsulating efficient is low, battery performance is poor, the life-span is short, and Colliod electrolyte for accumulator of the present invention is provided for this reason.
Technical scheme of the present invention is as follows:
A kind of Colliod electrolyte for accumulator that contains phyllosilicate is characterized in that forming by containing silica gel agent, thixotropic agent, compound additive and electrolyte, and described thixotropic agent is a phyllosilicate.
Further, the described silica gel agent that contains is SiO

Further, described polyalcohol is one or more the mixture in glucose, pentaerythrite, polyvinyl alcohol 1799 and the tartaric acid.
Further, described electrolyte is that mass concentration is 35～45% dilute sulfuric acid.
A kind of preparation method who contains the Colliod electrolyte for accumulator of phyllosilicate may further comprise the steps:
(1) will contain silica gel agent and be distributed in 35～45% the sulfuric acid solution and make colloidal dispersion,, obtain the dispersion liquid first 50～55 ℃ of following strong agitation 2～8 hours;
(2) the thixotropic agent phyllosilicate is scattered in the above-mentioned dispersion liquid first, and, reduces to room temperature, obtain dispersion liquid second 50～55 ℃ of following dispersed with stirring 6～12 hours;
(3) compound additive is dissolved in the above-mentioned dispersion liquid second, stirred 2～4 hours, make Colliod electrolyte for accumulator with excellent thixotropic fluidity and high-gel strength; In the Colliod electrolyte for accumulator, the content that contains silica gel agent is 2.0～10.0 weight %, and the content of phyllosilicate is 0.05～0.5 weight %; Described compound additive comprises the polyalcohol of 1～5 weight % that accounts for Colliod electrolyte for accumulator, the cobaltous sulfate of 0～0.5 weight %, the sodium sulphate of 0.5～3 weight % and the phosphoric acid of 3.5～5.5 weight %.
Colloidal electrolyte of the present invention has added the silicate particles that has layer structure on a small quantity, and it is of a size of 0.1～2 micron.Layered silicate particle has lamellar structure, in the aqueous solution, and the lamella imbibition, and finally be separated into the thin slice that thickness is about 1nm.Under stirring condition, particularly under the field of flow effect, laminar silicate can be orientated fast and form and be arranged in parallel along external force, can reduce the internal friction resistance that colloid flows, and reduces the colloid kinematic viscosity fast.Particle size is excessive, greater than 2 microns, in the colloidal electrolyte system will owing to weight excessive and may occur the precipitation; And particle scale is too small, and less than 0.1 micron, the alignment capability of lamella weakens, and does not have the effect that reduces colloidal electrolyte viscosity.This lamella state that presents in electrolyte has than bigger serface and contains the silicate particles of great amount of hydroxy group, can also play the effect that strengthens colloid intensity and stability.Therefore, add the laminar silicic acid salt particle of suitable yardstick after, colloidal electrolyte has better thixotropic fluidity and colloidal stability, can directly pour into to be used for storage battery production.Because this colloidal electrolyte thixotropic fluidity is big, viscosity only is 1/5th to 1/10th of common colloidal electrolyte, has improved encapsulating speed greatly, and the back is mended the glue probability and greatly reduced.With the storage battery that colloidal electrolyte of the present invention is made, dividing plate and pole plate can absorb more colloidal electrolyte, and battery capacity enlarges markedly, and prolong useful life.In addition, lamella silicate plate laminar surface has a large amount of electric charges, to being dissolved in the little metal ion in the electrolyte, as Pb
