INDUSTRIAL APPLICATION FIELD The present invention relates to a method for manufacturing an alkaline storage battery using a nickel positive electrode. Prior art and its problems Alkaline storage batteries such as nickel-cadmium,
There are roughly two types of nickel positive electrode plates, such as nickel-zinc and nickel-iron. One of them is called a sinter type, and the other is called a paste type. The former is made by impregnating a porous substrate with fine pores of more than ten microns, made by sintering fine nickel powder of 2 to 3 microns onto a core metal such as a perforated steel plate or nickel net, with a nickel nitrate salt solution, and then soaking it in water in an alkaline solution. It is manufactured using the so-called solution impregnation method, which is filled with oxide. In the latter method, in order to shorten the above steps, the nickel hydroxide active material itself is made into a paste form with water or the like and then directly filled. Therefore, the board is
Several tens of nickel hydroxide particles can be filled.
It consists of pores as large as several hundred microns, and a porous substrate having three-dimensionally continuous pores called a metal fiber sintered substrate or a sponge-like nickel substrate is used for these. In this paste type electrode plate, since the pores of the substrate are large, the current collection ability for the active material is poorer than that of the substrate of the sintered type electrode plate, so the active material utilization rate in the paste type is 50 to 60%. . This is a much worse drawback than the active material utilization rate of 90% in sintered electrode plates. As a method to overcome this drawback, a method has been proposed in which metal cobalt is added to the active material, dissolved in an electrolytic solution, and precipitated as cobalt hydroxide. However, in this method, since metallic cobalt has a zero valence, metallic cobalt cannot be dissolved without an electrochemical reaction such as Co→Co ++ +2e, that is, without charging. In addition, metal cobalt located in an upright place where electricity does not flow is not melted and is wasted. Therefore, in order to dissolve metal cobalt more completely and uniformly, before assembling it into a battery,
The drawback was that a complicated process of pre-charging treatment was required in the presence of an excess of electrolyte. Furthermore, in order to eliminate the drawbacks of the above methods, there is a method in which cobalt metal is added and immersed in an alkaline aqueous solution saturated or supersaturated with oxygen, thereby dissolving the cobalt metal without the pre-charging process. This is proposed in Japanese Patent Application Laid-Open No. 152371/1983. However, this method also requires a pretreatment step of bringing the alkaline aqueous solution into a saturated or supersaturated state, which has the disadvantage of making the work complicated. Purpose of the Invention The present invention eliminates the above-mentioned drawbacks, and eliminates the need for the pretreatment process as described above. By simply injecting an electrolyte into a battery, sealing it, and leaving it, a conductive network of cobalt hydroxide can be formed. It has the advantage of being formed. The reason for this is that Co()O is originally a valent compound, and even without charging (oxidizing) or using an oxidizing agent such as oxygen, the valence does not change when it comes into contact with an alkaline electrolyte. This is because it chemically changes into cobalt ions. Structure of the Invention In order to achieve the above object, the present invention mainly consists of divalent nickel hydroxide and has a molecular formula of CoO
A method for producing an alkaline storage battery using an unformed positive electrode plate made of a positive electrode active material mixed with cobalt oxide represented by the formula, which is characterized in that the battery is left to stand for 20 hours or more after injection of an electrolyte and then charged for the first time. . EXAMPLE An example of the present invention will be described in detail below. An aqueous nickel sulfate solution was dropped into an alkaline solution to generate nickel hydroxide, which was washed with water and dried to obtain an active material. On the other hand, an aqueous cobalt sulfate solution was dropped into the alkaline solution to generate cobalt hydroxide, which was washed with water and then vacuum dried at about 180°C to obtain CoO powder. 90 wt% of the nickel hydroxide powder thus obtained and 10 wt% of CoO powder were ground and mixed. This pulverized mixture and water in which a small amount of carboxymethyl cellulose was dissolved were added to form a paste. After distributing nickel fibers with a fiber diameter of approximately 25 μm using the air rate method, this paste was filled into a 2 mm thick, 95% porosity substrate sintered in a reducing atmosphere. After drying and adjusting the thickness, an unformed positive electrode plate with a thickness of 0.7 mm was obtained. This positive electrode plate, a negative electrode plate made of cadmium hydroxide and metal cadmium, a nylon separator, a caustic potassium aqueous solution with a specific gravity of 1.27, etc.
An AA size cylindrical nickel cadmium storage battery was fabricated. After injecting the liquid, this battery was left for more than 20 hours without being charged, and then charged for the first time to obtain a battery of the present invention. A capacity test was conducted to compare the battery of the present invention with other batteries that had been left for a certain period of time. The discharge capacity was tested by repeating 3 cycles. Table 1 shows the results regarding the relationship between the standing time and the discharge capacity and the relationship between the positive electrode plate composition.

Using an unformed positive electrode plate made of a mixed powder of CoO,
It can be seen that batteries that are first charged after being left for 20 hours or more after electrolyte injection are superior. If a battery using a positive electrode plate containing CoO is left for a certain period of time before being charged for the first time, its performance will improve. The cause of this is the reaction modeled mechanism shown in Figure 1, in which mixed CoO is mixed in an alkaline solution.
Co(OH ) 2 particles are dissolved as HCoO 2 -isocomplex ions, and when left standing, Co(OH) 2 particles precipitate on the surface of the active material nickel hydroxide particles and between the particles, connecting the current collector, and become conductive when charged. Changes to β-CoOOH.
This improves the conductivity between the active material particles. Therefore, in order to achieve a good connection by β-CoOOH, it is extremely important to leave the electrode before the initial charging to allow the additives in the electrode to dissolve and redeposit. If it is charged before it becomes a complex ion,
Since the particle surface of CoO is passivated with CoOOH or Co 3 O 4 , the internal CoO does not dissolve and HCoO 2 -
There is insufficient supply of Therefore, it is necessary to leave the battery for a period of time before charging it for the first time. Also, other than CoO, Co 2 O 3 , Co 3 O 4 , CoHO 2 ,
With cobalt compounds that are stable in alkaline solutions such as CoOOH, there was no change in performance. Although the above embodiment described a paste positive electrode using a nickel fiber sintered body, similar effects were obtained with other alkali-resistant metal fibers, sponge-like porous nickel bodies, and the like. Further, other alkaline storage batteries using the nickel electrode of the present invention as a positive electrode, such as nickel-zinc, nickel-zinc, etc.
A similar effect was found in storage batteries such as iron. Effects of the Invention As described above, according to the present invention, the utilization rate of the active material in the positive electrode plate is improved, and an alkaline storage battery with high performance and productivity can be provided, and its industrial value is great.
