Abstract
The utility model relates to a colloidal electrolyte storage battery with two layers of colloidal electrolyte. The bottom layer gel is composed of 8.0-10% sodium silicate, 6.0-8.5% silicon dioxide, 1-2% phosphoric acid, 0.05-0.15% sodium polyethylene sulfonate and diluted sulfuric acid. The top layer gel is composed of 15-22% sodium silicate, 3.0-6.0% sio-[2], 1-2% phosphoric acid and diluted sulfuric acid. The utility model which has the advantages of large capacity and good ability of starting improves the life time 1-2 times and prevents the phenomenon that colloidal electrolyte is easy to dry and fissure.
Description
The invention belongs to secondary cell, belong to colloid electrolyte lead-acid accumulator in more detail.
Have multiple colloidal electrolyte accumulator at present both at home and abroad.For example US4414302 and US4150199 patent mention all that with certain coagulating agent sulfuric acid electrolyte to be become solid-state, or utilize the ultra-fine enough sulfuric acid liquid of filler sorptions such as glass fibre, and reach the purpose that does not slop over.The GK86104708 Chinese patent has been narrated a kind of by Ludox and sulfuric acid method for making up thixotropic colloidal electrolyte.The silicon gel electrolyte lead acid accumulator of GG86200821 and GG86209279 Chinese patent, its gel electrolyte mainly is made up of silicon dioxide and sulfuric acid, and with used as stabilizers such as glycerol.The storage battery of GK86102428 Chinese patent, its electrolyte is mixed by sulfuric acid, sodium metasilicate, copra meal.
The invention of this class is because in discharge and charging process, and slight flexural deformation might take place pole plate and to cause pole plate to contact with filler insufficient, and charge acceptance is bad.Existing gel formula battery is only loaded the layer of gel electrolyte, in use for some time, tends to occur dry and causes the phenomenon that chaps, so internal resistance obviously increases, capacity obviously reduces.
In order to overcome the shortcoming of above-mentioned prior art, the present invention has designed the double colloidal layers colloidal electrolyte accumulator.
By the present invention, two kinds of different colloidal electrolytes are loaded in layering in the casing of storage battery.The bottom of submergence battery lead plate is a kind of grayish translucent gels, and it has the abundant sour ability that contains, but structure is tight, and enough intensity is arranged, to guarantee that perfection contacts fully between colloid and pole plate.Guaranteeing good electrical conductivity, is a kind of gel of milky short texture at the top of pole plate, and its porosity is very big, can all absorb the acid solution of emitting in the battery charging process, and be stored in its hole, to guarantee under any circumstance, do not have the liquid trickling in the battery.In addition, this top layer gel can allow gas communication effectively, and keeps the wettability of the close gel of Di Bu Cause, has prevented be full of cracks, has guaranteed the normal capacity of battery.So just overcome the disadvantage that has reduced charging performance in the existing silica-gel accumulator owing to the plate buckling distortion basically, also overcome the defect that be full of cracks takes place in the gel formula battery easily simultaneously basically.Its bottom gel of lead acid accumulator of the present invention is by the 8.0-10%(percetage by weight, down with) sodium metasilicate, the silicon dioxide of 6.0-8.5%, the phosphoric acid of 1-2%, sodium apolate and the dilute sulfuric acid of 0.05-0.15% are formed.The top layer gel is by the sodium metasilicate of 15-22%, the SiO of 3.0-6.0%
2, phosphoric acid and the dilute sulfuric acid of 1-2% are formed.
There is small amounts of phosphoric acid can guarantee the invertibity of electroactive material reaction on the pole plate in the gel, can extends the life of a cell.Add micro-sodium apolate, can improve the activity of pole plate, guaranteed capacity.
Accumulator structure of the present invention as shown in drawings.Wherein 1 is battery case, and 2 is negative plate, and 3 is positive plate, and 4 is dividing plate, and 5 is the bottom gel, and 6 is the top layer gel, and 7 is positive terminal, and 8 is negative terminal, and 9 is liquid injection hole.
Embodiment
Get a common 6-Q-60 automobile with lead acid accumulator container (volumetric(al) standards is 60Ah).Inject proportion and be 1.30 sulfuric acid solution to specified altitude, soaked 3-4 hour.Prepare first kind of colloidal electrolyte solvent or diluent by following proportioning: with the SiO of 9.2 parts of sodium metasilicate (weight, down together) and 0.1-1 μ m particle diameter
27.5 parts in powder is placed in the beaker and mixes, and adds 8.0 parts of distilled water, fully stirs to be uniform suspension-turbid liquid, adds proportion again and be 18 parts of 1.40 sulfuric acid solutions, adopts laboratory electric mixer (revolution is 1000rpm) vigorous stirring, is canescence to slurry.The mixing speed that suitably slows down then (about 100rpm) is slowly injected proportion and is 56.3 parts in 1.30 sulfuric acid, 1.0 parts of 85% industrial phosphoric acids, 0.1 part of sodium apolate.Vigorous stirring (1000rpm) mixes it.With soaking after acid solution in the battery pours out, inject the upper edge edge of the solvent or diluent of above-mentioned preparation to pole plate.Placed 40 minutes, colloidal electrolyte just can be solidified into the bottom gel.Then by second kind of colloidal electrolyte of following formulation: with 20 parts of sodium metasilicate, 5 parts of SiO
2, 25 parts of proportion is 1.30 sulfuric acid, stirs into milky thin pulp.Inject battery and make its even topped bottom gel, thickness reaches about 1cm.Become the Off-white solid gel layer of short texture after 1-2 hour, i.e. the top layer gel layer.This has just made double colloidal layers colloidal electrolyte accumulator of the present invention.
Colloidal electrolyte of the present invention can be in very wide temperature range be kept its solid state under (40 ℃-50 ℃) and the damp condition, and be full of the sulfuric acid solution of q.s, causing positive/negative plate normally to discharge and recharge, capacity reach be worth by norm when loading the sulfate liquid electrolyte more than 90%. Prove that through heavy-current discharge and real vehicle firing test lead-acid accumulator of the present invention starts the capacity index that ability reaches or be better than the ortho-sulfuric acid battery fully. Service life 1-2 doubly, all other electrical performance indexes all reach or are better than regulation among the GB5008.1-85. The real vehicle trial effect is good.
