Abstract
The invention discloses a method for infusing colloidal electrolyte in a valve-regulated lead acid battery (VRLA), which is characterized by comprising the following steps: a, cooling the well-prepared colloidal electrolyte; b, infusing the electrolyte from a battery infusion port; c, placing the battery in a vacuum box, closing the vacuum box and vacuumizing; and d, opening an air inlet valve, adding the residual electrolyte, vacuumizing, opening the air inlet valve after vacuumization and taking out the battery. In the invention, a part of the electrolyte is firstly infused, the whole battery is vacuumized, then the residual electrolyte is added, and secondary vacuumization is performed, thus ensuring that the colloidal electrolyte is evenly distributed at the interior of the battery, the battery has small internal resistance, the battery cell body is not deformed and the reliability is high.
Description
Technical field
The present invention relates to a kind of battery electrolyte and pour into method, particularly a kind of method for infusing colloidal electrolyte in valve-regulated lead acid battery (VRLA).
Background technology
At present, the colloid analysing valve control type lead-acid accumulator battery adopts colloidal electrolyte, in the colloidal electrolyte owing to added thickener-silica; Its viscosity is bigger, and is mobile relatively poor, when directly pouring into; The gas of inside battery is difficult to discharge, and electrolyte is difficult to be evenly distributed in utmost point crowd inside, thereby causes the local liquid that lacks of pole plate; The internal resistance of cell is big, and capacity is low; When adopting existing AGM battery vacuum to irritate the liquid method, because colloidal electrolyte ratio of viscosities sulfuric acid viscosity is big, vacuum degree requires higher; Battery inside and outside pressure reduction is big; The battery cell body is yielding, and the hermetically-sealed construction between battery case, the battery cover also can suffer damage, and causes battery bulging, sealing reliability to reduce.In addition, because the gelation rate and the temperature exponent function relation of colloidal electrolyte, temperature surpasses 35 ℃ of gelation rates and increases sharply, when ambient temperature is higher; In the electrolyte filling process, sulfuric acid reaction generation heat in lead oxide and the electrolyte in negative (life) pole plate, battery temperature raises; The electrolyte gelation rate accelerates, and causes colloidal electrolyte to be difficult to the inner evenly distribution utmost point crowd, even because gel can cause electrolyte in pole plate internal penetration difficulty; Polarization increases, and the internal resistance of cell is big, poor performance.
Summary of the invention
According to above deficiency of the prior art; The technical problem that the present invention will solve is: a kind of above-mentioned defective that solved is provided; Can guarantee that colloidal electrolyte evenly distributes at inside battery; The internal resistance of cell is little, and the battery cell body is indeformable, the method for infusing colloidal electrolyte in valve-regulated lead acid battery (VRLA) that reliability is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method for infusing colloidal electrolyte in valve-regulated lead acid battery (VRLA) is characterized in that may further comprise the steps:
A, the colloidal electrolyte for preparing is cooled off;
B, from the battery liquid-filling mouth, add electrolyte;
C, battery is put into vacuum tank, close vacuum tank, vacuumize processing;
D, open air intake valve, add residual electrolyte, vacuumize processing, vacuumize finish dealing with after, open air intake valve, take out battery.
Chilling temperature among the step a is-10 ℃～20 ℃.
Among the step b, at battery liquid-filling mouth place funnel is installed, is connected and sealed with battery, electrolyte is from funnel adding suitable for reading.
Among the step c, when adding 40%～70% electrolyte content, battery is put into vacuum tank, vacuumize processing, vacuum degree stops when reaching 0.04MPa～0.09MPa.
In the steps d, vacuumize when handling, vacuum degree stops when reaching 0.04MPa～0.09MPa.
The colloidal electrolyte for preparing is cooled to below 20 ℃, and to guarantee that battery temperature is not higher than 35 ℃ in the electrolyte filling process, the electrolyte gelation rate is low, is convenient to pour into; Special funnel is installed at battery liquid-filling mouth place, special funnel have into and out of, store the electrolyte function; Electrolyte is from funnel adding suitable for reading, and when vacuumizing, electrolyte can flow into inside battery through funnel, and the gas of inside battery can be discharged through bell mouth; Entire cell is put into vacuum tank, does not have pressure reduction inside and outside the battery, and the battery cell body is indeformable, and battery is bulging not, and sealing reliability is unaffected.
The beneficial effect that the present invention had is: method for infusing colloidal electrolyte in valve-regulated lead acid battery (VRLA) is through adding a part of electrolyte earlier; Entire cell is vacuumized, and then add residual electrolyte, vacuumize once more; Can guarantee that colloidal electrolyte evenly distributes at inside battery; The internal resistance of cell is little, and the battery cell body is indeformable, and reliability is high.
