Definitions
- the present invention relates to a method for removing lead sulfate (P b S_ ⁇ 4) film caused by sulfates instantiation phenomenon on the lead-acid battery electrodes.
- Japanese Patent Application Laid-Open No. 2000-156247 describes a lead-acid battery activator incorporating a circuit for generating a current pulse for peeling lead sulfate adhered to the surface of an electrode plate of a storage battery.
- Japanese Patent Application Laid-Open No. 2000-323188 discloses an activity of a lead-acid battery characterized in that immediately after a discharge pulse current is supplied, a charge pulse current having a larger electric quantity than the discharged electric quantity is applied. The method is described. In addition, the electric quantity of the discharge pulse current is 0.1 C or more, and the pulse It is described that the width is 0.001 to 1 second.
- the lead sulfate film is physically peeled off from the electrode, and only temporarily restores the characteristics of the lead storage battery. In other words, if the film is simply peeled off, much of the film will fall to the lower part of the electrode or float in the electrolyte without dissolving. There is a problem that the film adheres to the surface. In addition, since the dropped or suspended lead sulfate does not immediately dissolve in the electrolyte, there is a problem that the specific gravity of the electrolyte does not recover to a normal value while the specific gravity is low. Sulfuric acid had to be replenished.
- the thinned electrode plate may fall off together with the lead sulfate film at the same time, and the area of the electrode plate that causes a chemical reaction is reduced, so that there is a drawback that necessary electric power cannot be taken out.
- the present invention can dissolve the lead sulfate film formed on the electrode into fine particles without falling off and floating, thereby recovering the performance of the lead storage battery and extending the life of the lead storage battery. It is an object of the present invention to provide a new method for removing a lead sulfate film, which can be used for chemical conversion.
- a method according to the present invention comprises the steps of: A method for removing a lead sulfate film generated by a sulfation phenomenon, wherein a pulse current having a short pulse width accompanied by a skin effect is applied to intensively decompose a surface layer of the film.
- FIG. 1 is a diagram showing a circuit configuration of an apparatus used for the method for removing a lead sulfate film of the present invention.
- FIG. 2 is a diagram showing waveforms at points A, B, and C in FIG.
- FIG. 3 is a view showing a method of attaching an apparatus used for the method for removing a lead sulfate film of the present invention.
- FIG. 4 is a view showing a method of attaching an apparatus used for the method for removing a lead sulfate film of the present invention.
- FIG. 5 is a graph showing the measurement results of Example 1. BEST MODE FOR CARRYING OUT THE INVENTION
- a method according to the present invention is a method for removing a lead sulfate film generated by a sulfation phenomenon on an electrode of a lead storage battery, wherein a pulse current having a short pulse width with a skin effect is applied, It is characterized in that the surface layer of the film is intensively decomposed.
- a pulse current having a short pulse width accompanied by a skin effect is applied to the electrode on which the lead sulfate film is formed, so that the surface layer of the film, that is, the skin effect is applied.
- the charge concentrates in the range of skin depth (ski n depth) derived from, and the lead sulfate film is sequentially decomposed into lead ions and sulfate ions.
- the present invention is characterized in that, in the above-mentioned method for removing a lead sulfate film, a pulse current is applied, or after the pulse current is applied, charging is performed to reduce the decomposed film components.
- the lead ion and the sulfate ion generated by applying a current having a short pulse width are respectively converted into an electrode material and sulfuric acid by charging. Regenerates and battery performance is restored.
- the present invention is characterized in that in the above-mentioned method for removing a lead sulfate film, the pulse width of the pulse current is 1 second or less.
- the value of the pulse width for dissolving only the surface layer of the lead sulfate film without damaging the electrode itself is optimized. Also, since the current is very small, no noise is generated outside the battery.
- the method for removing a lead sulfate film according to the present invention is characterized in that the surface layer of the film is intensively decomposed by applying a pulse current having a short pulse width with a skin effect.
- the skin effect means a phenomenon in which high-frequency current is confined to the surface layer of the conductor and does not enter the inside. Due to this effect, the charge concentrates in the skin depth (sk in depth) determined by the pulse width, and the lead from the surface layer of the lead sulfate film, specifically, the tip of the protruding lead sulfate crystal. It is sequentially decomposed into fine particles into ions and sulfate ions.
- the lead sulfate film does not peel off or fall off from the electrode or float in the electrolytic solution in a crystalline state.
- a pulse current having a pulse width short enough to cause a skin effect is a very weak current and does not damage the electrode itself. And since there is almost no noise, there is the advantage that there is no adverse effect on the outside of the battery.
- the pulse width of the pulse current can be applied as long as it is within a range involving the skin effect. Specifically, it is preferable to set the time to less than ⁇ seconds, especially 0.1 / i to 1 ⁇ seconds. In this range, the calculated skin thickness is about 0.11 mm, so that charges can be concentrated on the surface layer without entering the inside of the film.
- the decomposition rate of the lead sulfate film is increased, but heat may be generated. Therefore, it is appropriately set in consideration of these balances. Specifically, it is preferably about 800 to 1200 times per second.
- a range of 12 to 108 V and a range of 10 to 12 O mA is preferable, but is not particularly limited because it varies depending on the pulse width and the number of pulses.
- the present invention is characterized in that charging is performed while applying a pulse current or after applying the pulse current.
- the re-dissolved lead ions are reduced by the pulse current and regenerated as a lead or lead dioxide electrode.
- the specific gravity of the electrolyte returns to the initial appropriate value, and the performance of the battery can be rapidly restored. This is an effect obtained only by decomposing the surface layer portion of the film into fine particles as in the present invention. This is not possible because lead crystals will reattach.
- the lead sulfate film is always decomposed and reduced, so that the progress of sulfation is suppressed and the performance of the lead storage battery can be maintained for a long time.
- Figure 1 shows 1 shows an example of a circuit configuration of the device.
- This device consists of a voltage detector, a reference voltage generator, a voltage comparator, an operation / non-operation switch, an oscillator, an amplifier, a waveform shaping circuit, a negative pulse current generator, and a conduction indicator.
- the operation / non-operation switch is provided for ON / OFF, and may not be provided.
- FIG. 2 shows waveforms at points A, B, and C in FIG.
- a negative pulse current having a short pulse width is generated and supplied to the lead-acid battery, whereby the lead sulfate film can be decomposed into fine particles.
- the external power supply may be provided separately for the power supply of the apparatus shown in FIG. 1, it is preferable to use the lead storage battery itself to be installed as the power supply.
- the device may be connected to the electrode of the lead-acid battery, and the means can be appropriately selected.
- a cigarette connector as shown in FIG. 3 can be used.
- the terminals shown in FIG. 4 may be directly attached to the lead storage battery using screws.
- the method for removing a lead sulfate film of the present invention can be used for various lead-acid batteries.
- Examples include passenger cars, trucks, buses, yachts, motor ports, fishing boats, ships, agricultural equipment, construction tools, construction equipment, electric forklifts, electric carts, golf carts, cleaning sweepers, electric wheelchairs, hospitals, banks, Examples include, but are not limited to, backup power supplies for facilities such as communication equipment, and lead-acid batteries for emergency radio such as police and fire departments.
- a dedicated pulse generator (12 V, 120 mW) having the circuit configuration shown in Fig. 1 is attached to a lead-acid battery, and a pulse current with a pulse width (T neg.
- the lead-acid battery was discharged while applying a voltage of 100,000 times per second.
- the current value was set to 10 mA.
- the lead storage battery according to the example was able to maintain a constant voltage for a longer time than the comparative example. Further, as shown in Table 2, the capacity of the example was larger than that of the comparative example. This indicates that the method of the present invention can contribute to prolonging the life of the lead-acid battery.c
- the lead sulfate powder was contained in dilute sulfuric acid. It was found that the film floated and the film was slightly adhered to the electrode, but the growth of the lead sulfate film was hardly observed in the example.
- the performance of a lead-acid battery that has deteriorated due to the formation of a film can be recovered, and the recrystallization of lead sulfate is prevented, preventing the progress of sulfation and extending the life of the lead-acid battery. Can be achieved. Further, since the applied pulse current is a very small current, the electrode itself is not damaged and no external noise is generated.
