Description

High discharge colloid storage battery

The utility model relates to a kind of colloid storage battery, particularly a kind of start type colloid storage battery.

At present, as the colloid storage battery of purposes such as vehicle, boats and ships, internal-combustion engine ignition starting and illumination, be that the perfusion colloidal electrolyte is realized in the common lead acid accumulator of routine.Though this colloid storage battery has advantages such as the acid of overflowing, acid mist are few, it is electrolytical lead acid accumulator that battery capacity is starkly lower than dilute sulfuric acid.Its 20 hour rate discharge capacity is about 80% only, does not meet rising of national Specification and employs lead acid accumulator 20 hour rate discharge capacities and be not less than 95% standard.Therefore, the colloid storage battery of making of said method is difficult to satisfy the requirement of starting type storage battery high-multiplying power discharge.

In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of 20 hour rate discharge capacities and is not less than 95%, is enough to satisfy the height discharge colloid storage battery of employing.

For achieving the above object, the utility model has been taked following measure:

1, the thin-wall construction that the employing of the shell of storage battery is acidproof, reinforced plastics is made is cancavo-convex vertical bar pole plate fixed support and the injection moulding of electrolysis tank inwall becomes one.Electrolysis tank becomes an overall structure with the cover plate heat-sealing that has liquid injection hole, thereby makes battery cell case have higher mechanical strength, has guaranteed its reliability of using in the environment of top ripple.

2, change the structure of the grid of grid type plate.The grid lug is by middle setting, the perpendicular rib of grid by the grid lug to around be the radiation-like attitude.Shorten the flow process of electric current so effectively, reduced the loss that polar plate voltage falls.Simultaneously, the circular structure of Cross section Design with the perpendicular rib of grid, have minimum circumferential length when making its sectional area identical, thereby strengthened effectively the anti-corrosion property energy of grid and the hold facility of plate active material, the useful life of having improved storage battery with other geometry area.

That 3, has improved grid type plate contains antimony amount and mounting means.The antimony amount that contains of the grid of grid type plate is controlled between the 0.5--1%, and the THICKNESS CONTROL of grid is between 1.45--1.95mm.Simultaneously, the paste spread type positive plate is arranged in the bushing type dividing plate made from glass fibre and paper fiber,, improves the utilance of active material to prolong the retention time of plate active material.

4, adopted the energization colloidal electrolyte, guaranteed that storage battery has higher capacity.

5, add the anti-acid acid filtering sheet above the electrolyte in storage battery, to be suppressed at the forfeiture with moisture content of separating out of acid mist in the charge and discharge process.

Through the discharge of the height after above-mentioned design colloid storage battery compact conformation, reasonable, battery capacity height, long service life, 20 hour rate discharge capacities 〉=more than 95%, meet the national standard of starting type storage battery fully.

Concrete structure of the present utility model is by providing in the accompanying drawing:

Fig. 1 is a structural representation of the present utility model

Fig. 2 be the utility model A to structural representation

Fig. 3 is the structural representation of the utility model grid

Figure is elaborated to the utility model below in conjunction with symbol:

High discharge colloid storage battery contains a housing 1 that employing is acidproof, reinforced plastics is made, cover plate 2.Housing 1 is thin-wall construction, and cover plate 2 is provided with fluid injection plug 3, pole leading-out terminal 4.Be the vertical bar polar plate bracket 5 of concave-convex structure and the cell wall of electrolysis tank 10 and be injection molded into one each other.Electrolysis tank 10 seals into a sealed monolithic structure with cover plate 2, to increase the intensity of housing.On the vertical bar polar plate bracket 5 of electrolysis tank, be fitted with positive plate 7, negative plate 8.Positive and negative pole plate is respectively by connector 6, be connected with positive and negative pole leading-out terminal 4 on the cover plate 2.Between positive and negative pole plate, be filled with energization colloidal electrolyte 12.On electrolyte 12, be equipped with an anti-acid acid filtering sheet 9.

The positive plate 7, the negative plate 8 that are inserted on the vertical bar pole plate fixed support 5 are grid type plate.Paste spread type positive plate 7 is arranged in the bushing type dividing plate made from glass fibre and paper fiber 11.The grid 13 of the positive and negative pole plate of paste spread type adopts low antimony alloy to make, the content of its antimony is about 0.5--1%, its thickness is 1.45--1.95mm, the lug 14 of its grid is by middle setting, perpendicular rib 15 on the grid 13 by the grid lug to around be the radiation-like attitude, the cross section of perpendicular rib 15 is a circular configuration.

Energization colloidal electrolyte 12 highly purified silica gel solutions of employing and sulfuric acid are formulated.In electrolyte, the solids content of SiO2 is 3.2--9%, and the content of sulfuric acid is 45--65%, and the two weight ratio is 0.07--0.14.In the energization colloidal electrolyte, also contain the stabilizer of 3--8% and the energy-increasing additive agent of 1.5--6.5%, all the other are ionized water.Stabilizer is made up of magnesium sulfate, aluminum sulfate, manganese sulfate and ionized water, wherein magnesium sulfate content be 6--10%, the content of aluminum sulfate is 10--16%, the content of manganese sulfate is 8--14%, all the other are ionized water.Energy-increasing additive agent is made up of cadmium sulfate, zinc sulfate and ionized water, and wherein the content of cadmium sulfate is 5--10%, and the content of zinc sulfate is 25--50%, and all the other are ionized water.

In addition, because the acid-proof filter disc that added above the electrolyte in battery 9 adopts the crisscross compacting of glass fibres to form, and this acid-proof filter disc not only has the good porosity, and has good heat-resisting, corrosion resistant and insulation property again.Therefore, in the charge and discharge process of storage battery, it can suppress separating out of acid mist effectively, acid-proof, filter gas both can have been played, keep the moisture content effect, can stop that again various harmful foreign material enter storage battery, have higher energy and high discharge performance thereby storage battery is remained.
