Abstract
The present invention relates to a method for the formation of polar plates by adding a catalyst to an electrolyte, which is a new technology for producing a lead storage battery. The existing production technology usually adopts the method that a diluted sulfuric acid electrolyte with certain specific weight is prepared in a formation tank; a weld positive polar plate and a negative polar plate are put in the tank; direct current is led in the tank for the formation of the polar plates. In the method; a certain quantity of catalyst is previously added to the electrolyte; after sufficient dissolution, the positive polar plate and the negative polar plate are put in the tank for formation. The method can improve the quality of polar plates, shorten the formation time of the polar plates and enhance the utilization rate of electric energy.
Description
The present invention is a kind of new technology that adds the polar plate formation method of catalyst in electrolyte, and it is applicable to that the pole plate of all kinds of lead accumulator products changes into.
Usually, in producing the chloride plate process, the dilute sulfuric acid electrolyte of preparation different specific weight in electrolytic bath, its proportion is generally at the 1.020-1.260 gram per centimeter
3, in the groove of packing into after positive/negative plate welded respectively, pass to direct current and carry out pole plate and change into.The major defect of this method is:
1. utilization rate of electrical is low, and power consumption is big, particularly the tubulose pole plate change into power consumption generally be the pole plate rated capacity 8-9 doubly, for example to change into power consumption be 219.5 ampere-hours to the tubulose pole plate of 25 ampere-hours, paste spread type start type pole plate 15 ampere-hours, changing into power consumption is 59 ampere-hours.
2. pole plate is of poor quality, and as tubulose pole plate brown lead oxide content only 40～60%, paste spread type start type pole plate brown lead oxide content is 60～70%.
3. because the time that changes into is long, in the hydrogen or oxygen gas that electrolytic process is separated out, have a large amount of acid mists, contaminated environment, harm worker health.
Change into speed for improving pole plate, reduce power consumption, on technique for making polar plate, once adopted following several method both at home and abroad:
1. as the described multistage charging system of SU-524264, promptly pole plate changes into time-division in some stages, and the forming current difference in per stage though this method can shorten the time of changing into, needs a cover automation equipment.
2. in positive plate, add a part of lead orthoplumbate, or brown lead oxide, utilization rate of electrical improved, but its effect is not remarkable.
3. add Sulfateses such as sodium, cobalt, ammonium in changing into electrolyte, the result causes serious expansion of negative plate and self discharge.
For solving the problem that prior art exists, the present invention is on the basis of existing production chloride plate technology, is the 1.020-1.260 gram per centimeter at proportion
3Dilute sulfuric acid electrolyte in dissolve in the catalyst of 1-11 grams per liter, catalyst system therefor is the metal oxide of aluminium, magnesium and their sulfate, after positive/negative plate is welded respectively, passes to direct current in the electrolytic bath of packing into and carries out pole plate and change into.
Following table is carried out the example that pole plate changes into for the electrolyte by the new technology preparation.
In dilute sulfuric acid electrolyte, carry out pole plate with above-mentioned catalyst dissolution and change into, the active material of positive/negative plate is not played any chemical change and electrochemical action, therefore, without any side effects to lead accumulator product itself.
The polar plate formation method that adds catalyst in the electrolyte, proof can improve the quality of pole plate by experiment, shortens pole plate and changes into the time, improves utilization rate of electrical.
