Abstract
The invention discloses an inner formation method of a colloid of a lead acid storage battery. Silica sol electrolyte is prepared from the following components in percent by weight: 3-6% of silicon dioxide, 0.2-0.5% of polyvinyl alcohol, 0.5-0.8% of glycerol, 0.5-0.8% of ethylene glycol, 0.1-0.2% of stannous sulfate, 1.0-1.5% of anhydrous sodium sulfate, 36% of dilute sulphuric acid with the density being 1.40g/cm<3> and the balance of water, and the prepared silica sol electrolyte is injected into a battery in a vacuum injection manner for charging and discharging. By means of the battery prepared according to a process disclosed by the invention, because the sulphuric acid and a silicon dioxide water solution are mixed uniformly in advance, the colloid with uniform and stable structure can be formed after charging and discharging, particularly, because oxygen transmission is suppressed due to the impermeability of the colloid in the early stage of life, the fully polarization of all negative polar plates can be maintained in a very long time by using a conventional charging and discharging method, and thus, the complete discharge capacity is maintained. Meanwhile, the actual amount of the suphuric acid in the battery can be controlled precisely and effectively, so that the assembly precision of a storage battery pack is controlled, and the consistency of the storage battery pack is increased, and the service life of the battery pack is prolonged.
Description
Technical field
The present invention relates to a kind of colloidal lead-acid storage battery formation method.
Background technology
Gelled lead acid battery is divided into two kinds in manufacturing process at present; The one, will solidify dried pole plate earlier and charge, again with charged pole plate, carry out combo according to weight; Use pole plate and dividing plate again; Through special tooling anchor clamps welding poling group, pack into and mould shell, be assembled into not intercell after the sealing.Through injecting with 95%～98%, density is 1.84g/cm
3The concentrated sulfuric acid and water and sodium sulphate diluted mixture after, density is 1.3～1.4g/cm
3The dilute sulfuric acid electrolyte that contains additive, again this dilute sulfuric acid electrolyte is mixed with 3%～5% silicon dioxide, becoming density is 1.26～1.27g/cm
3Colloidal electrolyte, quantitatively inject battery again, through battery is carried out charging and discharging, combo is accomplished the battery manufacture process.This is present comparatively common a kind of manufacturing process, because the difference of plate active material amount, dividing plate is inhaled the difference of acid amount, and there is very big-difference in inside battery with the actual acid content of capacity coupling, and the battery consistency that causes preparing group is poor, the life-span weak point.
The 2nd, use the concentrated sulfuric acid and water preparation density to be 1.26g/cm
3Dilute sulfuric acid, add the sodium sulphate of percentage by weight 1%～1.5%, 0.05～0.1% stannous sulfate more therein, pour in the storage battery through vacuum fluid injection mode; Through charging and discharging twice, in the discharge process, battery capacity is discharged to 105% of rated capacity the last time; After final discharging voltage is 9.60V～10.50V; Unnecessary electrolyte in the battery is poured out, with the silicon dioxide of percentage by weight 3～5%, 0.1～0.5% polyethylene glycol, 0.5～1.2% sodium sulphate, all the other are water, are mixed into colloidal electrolyte; After high speed shear, vacuum quantitative pours in the battery; Through battery is carried out charging and discharging, combo is accomplished the battery manufacture process.Though a kind of before this colloid technology is superior to, that its electrolyte mixes is inhomogeneous, self discharge is big etc. makes the battery consistency for preparing group poor, the life-span is short.
Summary of the invention
Technical problem to be solved by this invention mainly is to improve the open circuit voltage of battery and the consistency problem of discharge capacity of the cell, prolongs the useful life of colloid storage battery group.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme: the colloidal lead-acid storage battery formation method may further comprise the steps successively:
A. pour into colloidal electrolyte: according to following percentage by weight prepare silicon colloidal sol electrolyte: 3～6% silicon dioxide, 0.2～0.5% polyvinyl alcohol, 0.5～0.8% glycerine, 0.5～0.8% ethylene glycol, 0.1～0.2% stannous sulfate, 1.0～1.5% anhydrous sodium sulfate, 36% density are 1.40g/cm
3Dilute sulfuric acid, surplus is a water, and the Ludox electrolyte for preparing is poured in the battery through vacuum fluid injection mode;
B. discharge and recharge: battery charge, discharge to behind the perfusion colloidal electrolyte, recharge, discharge, in the discharge process, final discharging voltage is 9.60V～10.50V the last time, writes down discharge time, voltage;
C. battery combo: according to discharge time, the voltage of step B record, the battery that parameter is close carries out combo;
D. packing: the battery packages that combo is good is the finished product battery pack.
The density of said Ludox electrolyte is 1.27g/cm
3
Compared with prior art; Advantage of the present invention is: use the good battery of technology manufacturing of the present invention; Because of sulfuric acid and the silicon dioxide aqueous solution mix in advance,, particularly suppressed the transmission of oxygen in early days because of the impermeable character of colloid in the life-span through forming the colloid of structure stable homogeneous after discharging and recharging; Can in long time, use the conventional charging method of putting to keep the abundant polarization of all negative plates, keep full-discharge capacity.Can carry out accurately effectively control to actual sulfuric acid amount in the battery simultaneously, control the combo precision of batteries, improve the consistency of batteries, prolong the useful life of battery pack.
