Aerosil is the electrolyte gelling agent commonly used in the world at present, uses its obtained gelled lead acid battery
Function admirable.Johnson companies of the U.S., Hagen companies of Germany and GS companies of Japan all prepare plumbic acid using aerosil
Storage-battery colloidal electrolyte.Aerosil particle surface is rich in hydroxyl, easily by hydrogen bond action in aqueous sulfuric acid
Form three-dimensional netted gel structure.Even if only preliminary gelatification, the viscosity of electrolyte also can drastically be raised, led
Cause to be difficult to pour into the battery of compact texture, the problem of encapsulating is difficult as restriction promote colloidal electrolyte application main bottleneck it
One.Found during actual silica gel storage battery production, filling colloidal electrolyte is not carried out in placement process, can be because dioxy
Reunion between SiClx colloidal solid and form precipitation, make electrolyte overall distribution uneven, in turn resulted in battery performance
Reduction.If without special viscosity modifier, deflocculant and other additives, it is difficult the property for controlling silica-gel accumulator to be
Energy and quality.
Silicon dioxide microparticle is modified with high-molecular organic material and colloidal electrolyte is made, disclosed at present
Technical literature or patent document in it has been reported that for example, Chinese patent document CN1663984A (application numbers:
200410018708.6) a kind of modified polyorganosiloxane electrolyte and preparation method thereof is disclosed, containing a variety of modified polyorganosiloxanes,

Ether segment imparts colloid water solubility and hydrophily, plays emulsification, and can have good wetting action with battery lead plate.Carbon official
Carboxyl can be carried in siloxane structure, they can be formed with beneficial to H on the surface of gel particle+Conductive channel.With this kind of
Lead-acid accumulator low-temperature characteristics made from colloidal electrolyte is good, self discharge is small, long lifespan, with prominent electric recovery capability, and
And its good heavy current, the general lead-acid accumulator of high-multiplying power discharge Capacity Ratio is big by more than 30%.
But, prepare the support that thixotropy is good, the colloidal electrolyte of electrochemical performance also needs to various additives.
The viscosity of colloidal electrolyte can be improved using suitable additive, improve process for filling colloid, reduce the internal resistance of cell.Colloid electrode
Colloidal electrolyte is larger due to viscosity, and the active material above electrode is hindered during transmission, causes polar board surface
Easily form PbSO4Precipitation, reduces battery capacity, ultimate failure, and this also causes the capacity of colloid battery to be less than AGM battery.
It is unbalanced that colloid battery easily causes battery float in charging process, and colloidal electrolyte is easier in charge and discharge process
There is aquation lamination, solid-liquid occurs obvious interface, makes battery failure.Additive is added in colloidal electrolyte, is had

Property, so as to be easy to encapsulating.Also some organic polymers and complex, such as organic acid, ethers, tartaric acid, EDTA can conducts
Additive is added among electrolyte to improve the charge-discharge performance of battery.
In a word, organic polymer forms adsorption layer in the electrolytic solution, can prevent Pb2+The infiltration of ion, reverts to it
Active metal lead and brown lead oxide, complex can form complex ion with foreign ion therein in the electrolytic solution, so as to reduce
Self discharge, extends the service life of battery.After organic additive is added in right amount, it on the one hand can make gel networks rich in bullet
Property, it on the other hand can also suitably reduce the consumption of gel.So not only it is beneficial to the diffusion mobility of ion and gas, slows down water
Change lamination, and sulfation can be prevented to a certain extent, extend the life-span of gelled lead acid battery.But addition
Agent content is excessive, colloidal electrolyte aquation lamination is occurred.Conversely, additive level is very few, can not be to colloid
Electrolyte and battery produce Beneficial Effect.
Also useful ionic liquid as additives of lead-acid battery report.For example, triethyl group Ammonium hydrogen sulfate, benzyl sulphur
The addition of sour hydrogen amine plasma liquid can increase the utilization rate of positive active material, but add pole plate to a certain extent
The corrosion rate of grid.
In summary, mentioned at present in research both at home and abroad, selection appropriate addn species and additive amount could be made
