A. assembling: the pole plate that will solidify after drying finishes carries out combo according to weight earlier, with pole plate and dividing plate, by special tooling anchor clamps welding poling group, packs into and moulds shell, is assembled into the uncharged battery of not fluid injection after the sealing;
B. pour into dilute sulfuric acid: with the concentrated sulfuric acid and water preparation density is 1.240g/cm 3Dilute sulfuric acid, add the sodium sulphate of percentage by weight 1%~1.5%, 0.1~0.5% potassium sulfate, 0.2~0.6% stannous sulfate more therein, pour in the storage battery by vacuum fluid injection mode;
C. discharge and recharge I: charging and discharging twice, in the discharge process, battery capacity is discharged to 105% of rated capacity the last time, final discharging voltage is 9.60V~10.50V;
D. fall sour: unnecessary acid is poured out;
E. pour into colloid: 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;
F. discharge and recharge II: storage battery is charged, discharge time, voltage are write down in discharge again;
G. battery combo: according to the time that discharges and recharges, the voltage of step F record, the battery that parameter is close carries out combo;
H. packing: the battery packages that combo is good is the finished product battery pack.
Preferably, add 1% sodium sulphate, 0.5% potassium sulfate, 0.4% stannous sulfate among the described step B.
Preferably, add 1.25% sodium sulphate, 0.1% potassium sulfate, 0.6% stannous sulfate among the described step B.
Preferably, add 1.5% sodium sulphate, 0.3% potassium sulfate, 0.2% stannous sulfate among the described step B.
Preferably, with the silicon dioxide of percentage by weight 3%, 0.3% polyethylene glycol, 1.2% sodium sulphate, 95.5% water, be mixed into colloidal electrolyte in the described step e.
Preferably, with the silicon dioxide of percentage by weight 4%, 0.5% polyethylene glycol, 0.5% sodium sulphate, 95% water, be mixed into colloidal electrolyte in the described step e.
Preferably, with the silicon dioxide of percentage by weight 5%, 0.1% polyethylene glycol, 0.9% sodium sulphate, 94% water, be mixed into colloidal electrolyte in the described step e.
Compared with prior art, advantage of the present invention is: the battery that uses technology of the present invention to make, because of quantitatively controlling depth of discharge, finally added the not vitriolated silicon dioxide aqueous solution, after overcharging, sulfuric acid after the discharge mixes naturally with the silicon dioxide aqueous solution, and the colloid of formation structure stable homogeneous can carry out accurately effectively control to actual sulfuric acid amount in the battery, the combo precision of control batteries, improve the consistency of batteries, prolonged the useful life of battery pack.Simultaneously, in production process, the dilute sulfuric acid electrolyte of pouring out, by filtering and adjusting its density, additive component, reusable edible has reduced the spent acid discharging, more energy-conserving and environment-protective.
