Abstract
The invention discloses an additive of colloidal electrolyte, which contains the following components with the following weight percentages: 0.2 to 3 percent of phosphoric acid, 1 to 2 percent of sodium sulfate and 0.1 to 1 percent of stannous sulfate. The additive contains the phosphoric acid, the sodium sulfate and the stannous sulfate; after the phosphoric acid is added into the colloidal electrolyte, the softening rate of the anode active material PbO2 of a accumulator can be reduced, and the PbO2 loss can be reduced, thereby prolonging the cycle life of the accumulator and reducing the plate sulfation when the accumulator is kept after being completely discharged. The sodium sulfate and the stannous sulfate added into the colloidal electrolyte of the accumulator can effectively inhibit the accumulator sulfation.
Description
Technical field
The present invention relates to the colloidal electrolyte in storage battery field, particularly colloid storage battery.
Background technology
Colloid storage battery is meant with the colloidal electrolyte to be that the alternative sulfuric acid of medium is the storage battery of medium, and sulfuric acid in this colloidal electrolyte and water in the silicon gel network, are " soft solid-state shape gel " by " storage ", show solid-state shape during transfixion.When battery is recharged, because the sulfuric acid concentration increase in the electrolyte makes it " thickening " and produces with the crack, " brine electrolysis " reaction in charging later stage makes the anodal oxygen that produces be absorbed by negative pole by this countless crack, and further be reduced into water, thereby realize storage battery sealing circular response.Sulfuric acid concentration during discharge in the electrolyte reduces makes it " thinning ", becomes the preceding rare gluey attitude of perfusion battery again.Therefore, colloid battery has the effect of " non-maintaining ".
Existing colloidal electrolyte is generally disposed according to a certain percentage by aerosil and certain density sulfuric acid solution and forms, and it still is lead acid accumulator in essence.The negative pole of lead acid accumulator is that spongiform lead is made, and positive pole is that brown lead oxide is made, and spongiform lead and brown lead oxide are active material, is 1.300-1.330g/cm at proportion
3During reaction, spongy lead and brown lead oxide and sulfuric acid reaction generate lead sulfate, and the short texture of this lead sulfate, crystal are very tiny, and electro-chemical activity is very high, during charging, can regenerate the anodal brown lead oxide and the spongy lead of negative pole under the function of current.As seen, under normal condition, this electrochemical reaction is a completely reversibility.
The process that generates lead sulfate during discharge also is called " salinization reaction ", " vulcanization reaction ", and activity is very strong in a period of time after this sulfate generates.If uncharged during this period of time, fail in time to be converted into spongy lead and brown lead oxide.Descend with temperature, active lead sulfate can recrystallize into and be the bigger crystal of particle.This white coarse grain lead sulfate electric conductivity is very poor, indissoluble is separated, and can not restore into spongy lead and brown lead oxide during charging, has formed irreversible salinization (sulfuration), causes that battery capacity descends, the cycle life of battery shortens.
Summary of the invention
The auxiliary additive that the purpose of this invention is to provide a kind of colloidal electrolyte, it can effectively suppress the colloidal electrolyte sulfuration, thereby improves the cycle life of colloid storage battery.
Technical scheme of the present invention is such: the auxiliary additive of colloidal electrolyte comprises the following component of the percentage by weight of colloidal electrolyte: phosphoric acid 0.2-3%, sodium sulphate 1-2% and stannous sulfate 0.1-1%.
The potassium sulfate of 0.5-2% that also comprises the weight of colloidal electrolyte.
The magnesium sulfate of 0.5-2% that also comprises the weight of colloidal electrolyte.
The cobaltous sulfate of 0.5-2% that also comprises the weight of colloidal electrolyte.
After adopting such scheme, the additive of colloidal electrolyte of the present invention comprises phosphoric acid, sodium sulphate and stannous sulfate, can reduce battery anode active substance PbO behind the adding phosphoric acid in the colloidal electrolyte of storage battery
2Softening rate, reduce it and come off, thereby can improve the cycle life of storage battery, but also can alleviate the sulfation of pole plate when shelving behind the storage battery deep discharge.Adding sodium sulphate and stannous sulfate have the good restraining effect to the generation of battery sulfuric acid salinization in the colloidal electrolyte of storage battery.
Current value discharge cycles test with one times of capacity of storage battery of 12V40Ah is an example, and following table is the dark cycle-index of having added colloidal electrolyte behind a additive of the present invention and commercially available colloidal electrolyte-discharge time contrast table.
Can find out from last table, when commercially available colloidal electrolyte is recycled to the 17th time deeply, reduce to discharge time 28 minutes and 08 second, can't normally use; And the colloidal electrolyte that has added additive of the present invention is when being recycled to the 48th time deeply, and discharge time is also basic to keep initial data.Can find out that thus the additive of colloidal electrolyte of the present invention can effectively suppress the colloidal electrolyte sulfuration really, improve the cycle life of colloid storage battery.
