beneficial effect: the present invention makes Battery formation change into time shorten more than 40%, and charge volume reduces more than 20%, and battery combo rate improves more than 5%, and battery cycle life improves more than 20%, and eliminate simultaneously and take out sour technique after changing into, production cost has decline by a relatively large margin.
Embodiment
Reaching object to make technological means of the present invention, creation characteristic, workflow, using method and effect is easy to understand, setting forth the present invention further below.
A kind of valve-regulated lead-acid battery internal formation process, comprises the following steps:
(1), battery acid adding: whole acid adding process be divided into twice, amount error ± 0.5% of each acid adding.Acid adding amount is 80% ~ 90% of total acid adding amount first, is then transferred to by battery electrode foil chemical reaction shelf carries out charging to change into; Residual acid amount adds in the pilot process changed into; Adopt quantitative acid dosing, be in order to cancel change into the later stage take out sour technique, reduce artificial, reduce production cost.
(2), change into: having of whole formation process is discharged for three times and four chargings, and the online discharge and recharge time only has 50h ~ 60h, and total charge volume is 8 ~ 9 times of battery rated capacity.
In theory, the active material that negative pole changes into is velvet-like lead sponge, and be a kind of conductor, resistance is little, and the active material that positive pole transforms is brown lead oxide, and be semiconductor, resistance is large.Facts have proved, when negative electrode active material is fully transformed, positive active material has only transformed about 80%.Change into if continue to charge the battery, just certainly will cause negative electrode active material overcharge, the reaction of the brine electrolysis that simultaneously produces is more violent, the air scour dividing plate that reaction produces and pole plate, the serious curtailment life-span of battery.Therefore, design battery first acid adding amount only has 80% ~ 90% of total acid content, allows battery have one section of lean solution state in the middle and later periods changed into.In this stage, the oxygen that brine electrolysis produces arrives negative terminal surface by dividing plate micropore, and produce chemical reaction with the active material lead of negative pole, produce lead oxide, lead oxide is sulfuric acid reaction, regenerates lead sulfate.The one part of current now acting on negative pole can be reduced into lead sponge lead sulfate.After circulation like this, positive active material transforms fully, and the electric current acted on negative pole is because shunting one part of current is for oxygen cycle, and the electric current being directly used in brine electrolysis diminishes, and just diminishes to the injury that battery causes.
Having of whole formation process is discharged for three times and four chargings, and be convenient to the conversion of active material, the online discharge and recharge time only has 50h ~ 60h, and total charge volume reaches 8 ~ 9 times of battery rated capacity.
