Description of the Related Art In a battery, it is important to maintain the function of the battery that a positive electrode plate and a negative electrode plate are separated by a separator, and a short-circuit test for detecting a short circuit between the positive electrode plate and the negative electrode plate is performed on the battery. It is performed in the manufacturing process. As such a short-circuit inspection method, there is a method of measuring the insulation resistance between the positive electrode plate and the negative electrode plate and determining the presence or absence of a short-circuit based on the resistance value.
In the actual manufacturing process, a relatively high voltage of several hundreds of volts to several tens of kV is applied between the terminals of an unfilled battery, and the current flowing at that time is measured to measure the insulation resistance indirectly. The method is generally performed, and in this case, the presence or absence of a short circuit is determined based on the level of the current value.

の影響を大変受けやすかった。[0003] In a battery, especially a large-capacity battery of several tens Ah to several thousand Ah used for large-scale communication backup, the sum of the facing areas of the electrode plates is very large, and the electrode plates and the separator absorb the moisture in the air during battery production. It's easy to do. In addition to the large battery volume, the water once absorbed, especially to the center of the cell, does not easily evaporate out of the battery. Such a cell that has absorbed moisture in the air has a low insulation resistance, and a battery without a short circuit may be erroneously determined as a short circuit in the short circuit test as described above. For example, FIG. 5 is a diagram showing the relationship between the current value flowing at that time and the ambient humidity when a DC voltage of 300 V is applied to an uninjected battery that has been pseudo-short-circuited and an uninjected battery that has no short circuit. As can be seen from FIG. 5, the current value increases as the atmospheric humidity increases. Especially the atmospheric humidity is 80
At about RH%, it is difficult to determine the difference between the short-circuited battery and the current, because the difference is small. Further, as an example, when the current value for judging the presence or absence of a short circuit is set to 60 mA, when the ambient humidity becomes higher than around 70 RH%, a battery having no short circuit will be erroneously determined to have a short circuit.
As described above, the conventional battery short-circuit inspection method is very susceptible to the influence of atmospheric humidity.

You. This judgment is based on the principle of the capacitor,
Capacitance is obtained by applying a voltage between the pole terminal and the negative terminal.
The charge is charged based on the amount, and the charge is applied between these terminals.
A difference occurs. At this time, the short-circuit resistance between the positive and negative plates is small.
In short, the potential of both poles becomes more equal and the charge is charged
Potential difference (VTwo) Approaches zero. On the contrary

Large potential difference (VTwo) Occurs. This potential difference (VTwo)of
The presence or absence of a short circuit is determined based on the value. This potential

The potential difference (V Two)
It is necessary to strictly define the timing to determine. here
The fact that the battery 1 needs to be inspected without liquid
Needless to say. As the battery 1, unleaded lead storage
Most preferably, it is applied to batteries. Unformed lead storage
In batteries, both the positive and negative electrode active materials are basic sulfuric acid.
Mixture of lead and lead sulphate and very small amounts of metallic lead.

It is difficult to detect a short circuit by the conventional short circuit inspection method.
Further, the battery short-circuit inspection method of the present invention is a glass fiber separator.
It can be applied to batteries using mat separators such as

Because the subject of the present invention becomes remarkable.
It is. Use other separators, such as gel electrolyte.
A frame such as that used in lead-acid batteries used
When used as a mat, the mat
There is no hygroscopic material like parator
The influence of atmospheric humidity is not so large even in the case of the fault detection method.
In addition, the short-circuit inspection method of the present invention employs a positive electrode plate and a negative electrode per cell.

It is preferable to apply to a large capacity battery. Especially like this
Batteries with a large sum of the opposing areas absorb moisture per cell volume
High performance, more easily absorbs moisture due to increased atmospheric humidity
The risk of misjudgment in short-circuit inspection increases.

If moisture has absorbed into the core, place the battery in a low-humidity atmosphere.
Can hardly remove the water at the center of the cell.
Therefore, the problem of the present invention becomes more remarkable. Also this
The total sum of the facing areas is 2000cmTwoBatteries that exceed

A sealed lead-acid battery equivalent to 0 Ah (10 hour rate) was used.
The positive electrode plate has PbO 2 as the main active material and has a width of 1
40 mm, height 400 mm, thickness 5.5 mm
Five negative plates are composed of Pb as the main active material and have a width of 1
40 mm, height 400 mm, thickness 3.0 mm
Using 6 sheets, width 140mm, height 405mm, thickness 4.8
A single battery was formed using a glass fiber separator of mm. Next, battery B has the same dimensions and number of positive plates, negative plates, and separators as battery A, but the active material is not yet formed. For the unformed active material, apply a paste obtained by kneading lead powder (mixed powder of lead and lead oxides such as lead monoxide and lead oxide) with water and dilute sulfuric acid to a lead alloy lattice according to a standard method. And then aged and dried under a temperature condition of about 40 ° C to 60 ° C. The unformed active material is a mixture of basic lead sulfate (generally tribasic lead sulfate), lead sulfate, and metallic lead for both the positive electrode plate and the negative electrode plate. The total sum of the opposing areas of the positive electrode plate and the negative electrode plate of these batteries A and B is 16800 cm 2 . For each of these batteries A and B, 100 batteries were prepared. In addition, 50 out of 100 pieces each had a fragment of the active material interposed between the positive electrode plate and the negative electrode plate to produce a pseudo short-circuit battery. A voltage of 100 V DC (V 1 in the embodiment) was applied between the terminals of these batteries for 5 seconds (t 1 in the embodiment). One second after removing this voltage (t 2 in the embodiment), the potential difference (V 2 ) between the positive terminal and the negative terminal was measured.

5 ° C. and humidity were changed in the range of 30 to 100 RH%, and the erroneous determination rate at this time was investigated. The result is shown in FIG. The misjudgment rate is the rate of batteries that did not cause a pseudo short circuit and was judged as having a short circuit (hereinafter, the first misjudgment), and the short circuit test determined that there was no short circuit for the battery that caused a pseudo short circuit. The rate of the batteries (hereinafter referred to as “second erroneous determination”) was examined.

On the other hand, as shown in FIG. 3, the first erroneous determination rate is extremely low in the example of the present invention as compared with the conventional example. In particular, the erroneous determination rate was 0% for the battery B composed of an unformed electrode plate. Here, in the conventional example, the first erroneous determination rate sharply increased as the humidity increased in both the battery A and the battery B. Here, the influence of humidity on the first erroneous determination rate of the battery B using the unformed electrode plate is larger than that of the battery A using the formed electrode plate. This is presumed to be due to the difference in hygroscopicity between the unchemically activated material and the chemically activated material.
