Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead-

The present invention relates to an apparatus for extending the life of a lead-acid battery, for example, by applying a vibrating magnetic field in accordance with a crossing of a low-frequency intermittent direct current and a high-frequency intermittent direct current to a pole plate of a lead- The present invention relates to a lifespan extension device for lifting a life of a lead-acid battery by allowing the lifetime of the lead-acid battery to be greatly extended by activating the regeneration and restoration action of the formed sulfate precipitate and actively removing sulfate from the electrode plate.

Generally, lead-acid batteries used in automobiles are secondary batteries that can be charged and discharged. This lead-acid battery is formed by using dilute sulfuric acid (H ₂ SO ₄ ) as an electrolytic solution and by applying dioxide (PbO ₂ ) to the anode and sponge-like lead (Pb) (PbSO ₄ ), and when the current flows from the outside, the lead sulfate is changed again to lead dioxide and lead.

Here, when the active material of the lead-acid battery changes into lead sulfate (PbSO ₄ ), the lead-acid battery is discharged. Conversely, the lead sulfate of the positive electrode and the negative electrode of the lead- It is a well-known fact that the battery is charged at the time.

As shown in FIG. 1, the lead-acid battery includes a positive electrode plate 1 and a negative electrode plate 20, which are coated with an active material, and are alternately stacked in multiple sheets, A non-conductive separator 3 is formed on the plate group together with the positive electrode plate and the negative electrode plate. Depending on the capacity of the lead-acid battery, a plurality of such electrode plates are connected in series and accommodated together with the electrolytic solution in the precursor (4).

The positive electrode plate 1 and the negative electrode plate 2 are of various types according to their manufacturing techniques. For example, there is a paste electrode structure. The structure of such a paste-type electrode will be briefly described. The paste-type electrode is composed of a grid-shaped substrate and a paste-like active material coated on such a substrate. The substrate is an alloyed gold to which a small amount of calcium (Ca) is added in order to enhance mechanical strength. In general, the molten alloy is cast into a mold and cast by gravity or continuous rolling. The active material is a part which plays an important role in the performance of a lead-acid battery. The paste is prepared by continuously applying a paste-like paste in which fine lead oxide is mixed with a dilute sulfuric acid aqueous solution on the substrate in a coater, aging, drying, Which is produced through a conversion process.

However, in the above-described lead-acid battery, during the course of charging and discharging cycles, the sulphate stuck at the time of discharging may not be released upon charging but may adhere to the battery, which is called sulfation (sulfuric acid softening) phenomenon. And this sulfation phenomenon becomes worse as the battery discharges more, and the more times the charge and discharge cycle is, the worse it becomes.

The sulphate (SO ₄ ) is an insulating film which is bonded to the electrode plate or bonded to each other in the active material layer so as to cover the electrode plate in the form of a film. This sulphate prevents the passage of chemical and electric reactions, The voltage and the capacitance and the specific gravity of the lead-acid battery are reduced, and sulfur molecules forming sulfur dioxide in the lead-acid battery are removed from the electrolyte.

The presence of clean plates and strong electrolytes is very important in order for a lead-acid battery to receive a charge current and to supply a strong discharge current. Of course, in the case of strong recharging, a certain amount of sulphate is removed, but not all of it can be removed, and ultimately after a certain period of discharge, the electrode plate of the rechargeable battery is covered with sulphate which makes effective recharging impossible, Corrosive batteries are eventually discarded.

The above-described sulfation phenomenon has a bad influence on the load test of the lead-acid battery. For example, the phenomenon that the electrode plates of the lead storage battery are severely corroded and the electrode plate materials sink to the bottom of the lead storage battery is caused by maximizing the surface area of the lead plate in the manufacture of the lead storage battery and making it highly porous for maximum current discharge in a short period of time . In other words, as the high current capacity is produced in a short time, the sulfate easily enters into the hole of the electrode plate and rapidly expands to the crystallization state, which causes the active material layer of the electrode plate to be destroyed, Shortening of life time is easily occurred.
