Abstract
The invention belongs to the preparation method of the thixotropy colloidal electrolyte that a kind of lead accumulator uses.It is the gelinite of the one-component made by Ludox and sulfuric acid, have thixotropy good, low temperature resistant, be convenient to the battery capacity advantages of higher of storing, transporting and operating, pouring into.
Description
The invention belongs to the compound method of the colloidal electrolyte of lead accumulator.
The present invention is a kind of method for making up thixotropic colloidal electrolyte, be characterized in the colloidal electrolyte of preparing in this way be the thixotropy gel body, with one-component store, transportation and directly pour in the battery discharge capacity of the cell height.
The method of preparing colloidal electrolyte in the past in the present invention be with contain silica gel agent (as sodium metasilicate, silicon solution or amorphous Si O
2Powder) and after the sulfuric acid mixing pour in the lead accumulator, generate gelinite, replace sulfuric acid to make electrolyte, prevent that battery from leaking acid, extending battery life.
Nineteen eighty-three " Jiangsu coal science and technology " has been reported a kind of method of preparing colloidal electrolyte.Industrial metasilicate is diluted with water to proportion 1.030～1.060 gram per centimeters
3, the proportion with equal volume is 1.50 gram per centimeters again
3Sulfuric acid mix, pour in the new light board KS-8 mineral light of coal mountain.Compare with the sulfuric acid mine lamp, its internal resistance increases about 1 times, and discharge capacity descends 12.6%, and the life-span on average shortens 1 month.
1980 " safety of coal mines " report: sodium metasilicate has been produced pure silicon solution and proportion 1.50 gram per centimeters through ion-exchange
3Sulfuric acid mix, the colloidal electrolyte good stability of producing, the colloidal electrolyte mine lamp of recording has prolonged about 1 year than sulfuric acid mine lamp useful life.
British patent 2088623(1982) introduced the method for making lead accumulator thixotropy colloidal electrolyte.Gel is the amorphous Si O of fines
2Powder, trade name Aerosil 200,12 millimicrons of particle diameters, 200 meters of specific areas
2/ gram.At proportion 1.06 gram per centimeters
3Sulfuric acid in add electrolyte total weight 12% by quick stirring Aerosil200(can add 2% H in addition
3PO
4), make colloidal sol, pour in the storage battery.Along with charging process, sulfuric acid concentration raises, and sol system gradually becomes gel and has thixotropy.The storage battery no leakage, long service life.
In original technology, there is following shortcoming:
1. make gel with sodium metasilicate, gel is fast, is not easy to operation, and colloidal stability is poor;
2. the colloidal electrolyte battery capacity is low;
3. colloidal electrolyte necessary " matching while using " uses inconvenience;
4. the external amorphous Si O that generally adopts
2Powder and its aqueous liquid dispersion, preparation are complicated, domestic source of goods difficulty.
The present invention is more in conjunction with the producer of domestic production silicon solution, but product quality differs, so by selecting suitable Ludox and changing the proportioning of colloidal electrolyte, improve battery capacity.Utilize the thixotropy of this product to be mixed with the colloidal electrolyte of one-component.
For kind, content and the sulfuric acid content of studying Ludox to the colloidal electrolyte Effect on Performance, observe the thixotropy of gelinite, the present invention has carried out following test.
One, choosing contains SiO
2Weight ratio is 6 kinds of 10～13% homemade Ludox, and its particle size analysis is 2～30 millimicrons, and specific area is respectively 50,100,200,300,400 and 500 meters
2/ gram.With above Ludox is 1.50 gram per centimeters with isopyknic proportion respectively
3Sulfuric acid mix, inject a kind of transparent KS-7 mineral light (this battery rated capacity is 7 ampere-hours) with syringe after being chilled to room temperature.Behind the electrolyte gel that injects, carry out initial charge and volume test by the MT26-85 of Ministry of Coal Industry standard, the result is respectively 8.1,7.9,7.6,7.4,6.3,6.2 ampere-hours.
Test is found, the SiO in Ludox
2The micelle specific area is less than 100 meters
2During/gram, though battery capacity is higher, the obvious aquation of colloidal electrolyte, leakiness acid.
Two, adding contains SiO in the glass container that electromagnetic stirrer and water cooling system are housed
2Ludox 300 gram of weight ratio 6～30% drips sulfuric acid 300 grams (make in the electrolyte that makes sulfuric acid content than between 30～48%) under high degree of agitation.Reaction temperature remains on 10～40 ℃.After dropwising, when temperature is reduced to below 20 ℃, this electrolyte is injected the KS-7 mineral light with syringe.Behind the complete gel of electrolyte, carry out initial charge and survey battery capacity.
When colloidal electrolyte contains SiO
2Be lower than at 5% o'clock, very low, the easy fragmentation of gel strength, aquation; When containing SiO
2Be higher than at 10% o'clock, system viscosity is big, and gel is fast, be difficult to pour in the battery, and battery capacity descends.So, with the SiO in the colloidal electrolyte
2Content suits between remaining on 5～10%.
Sulfuric acid weight ratio in the colloidal electrolyte is lower than 35% or be higher than at 45% o'clock, and battery capacity is lower.Test is found, is worked as SiO
2Weight ratio is at 5～10% o'clock, sulfuric acid content is remained on 35～45% between the time, KS-7 mineral light capacity is 7.4,8.1,9.0,7.3 ampere-hours.And the sulfuric acid mine lamp capacity that identical examination is trampled under the condition is 8.5 ampere-hours.
During taking-up one batch sample is packed plastic bottle into from this test, at room temperature place gel after a few hours.Place after 14 days, shake plastic bottle or stir electrolyte, gelinite becomes liquid very soon, its mobile recovery as before.These electrolyte are poured in the same battery, and battery capacity is more than 8 ampere-hours.
Use amorphous Si O
2Powder replaces Ludox to do above-mentioned thixotropy test, obtains same result.
From above-mentioned test as can be seen, when the particle size analysis of Ludox is 2～30 millimicrons, specific area is 50～500 meters
2/ gram and contains SiO after sulfuric acid mixes
2At 3～15% o'clock, can be mixed with colloidal electrolyte.But specific area is 100～300 meters
2/ gram, gained colloidal electrolyte good stability, battery capacity height.
Work as SiO
2Content is 5～10%, and sulfuric acid content is that 35～45% o'clock gained colloidal electrolyte gel states are good, thixotropy is good, and the battery capacity height.
Colloidal electrolyte with method preparation of the present invention is compared with original technology, and following advantage is arranged:
1. improve the capacity of colloidal electrolyte battery, can meet or exceed the capacity of sulfuric acid battery;
2. colloidal electrolyte of the present invention has good thixotropy, stores, transports and use with one-component, the preparation before having avoided using, and operation is not subjected to time restriction, without any waste;
3. colloidal electrolyte solidifying point of the present invention is low, can use under any cold climate condition.
