FIG. 1 is a cross-sectional view of the electrolyte injection tube used in the present invention, and FIG. 2 is a schematic side view of the centrifugal liquid injection device used in the present invention. In the figure, 1 is an injection tube, and 2 is a sphere that closes a juice port 3 inserted into the tube. Place the battery 5 after the electrode group has been inserted into the battery support shown at 4 in FIG. After mounting on the tube support 6, an electrolytic solution is injected into the injection tube. At this time, since the sphere 2 closes the injection port 3, the electrolyte is securely held within the injection tube.Next, when the motor 7 is rotated, the rotation shaft 8 of the motor and the bar connected to it are rotated. The rotating part 9 having a shape rotates. When rotation begins, the battery support 4 is swung outward with respect to the rotating shaft 8 and moves around the support holding shaft 1o as a pivot center due to centrifugal force. Figure 3B shows the state of the sphere 2 in the injection tube in a stationary state and in a rotating state. That is, in a stationary person, the sphere 2 closes the injection port 3 due to the taper (taper angle θ') at the inner bottom of the injection tube, and remains held within the injection tube even when the electrolyte is injected.

管内底部のテーパ角θ′よりも回転状態での注入管の開
き角度θを小さくする。On the other hand, in the rotating state, the sphere 2 moves outward with respect to the rotation axis due to centrifugal force, so the injection port 3 becomes open and the electrolyte is discharged from the injection tube. At this time, the opening angle θ of the injection tube in the rotated state is made smaller than the taper angle θ' of the inner bottom of the injection tube.

。In order to compare with the conventional example, a nickel positive electrode and a cadmium negative electrode were spirally wound through a separator made of nylon non-woven fabric to form the electrode group 5, and this was inserted into a battery can. A cadmium battery was used, and 6.0 g of KOH having a specific gravity of 1.26 was injected as an electrolyte. The conditions of the device are that the radius of the bar-shaped rotating part 9 is 100+
m, the rotation speed is 600 rpm, and the inner diameter of injection tube 1 is 15
+m, a 9mm diameter stainless steel bulb was placed inside the injection tube. Further, the taper angle of the inner bottom of the injection tube was 16oo, and the opening angle of the injection tube during rotation was 15o. As a result, in the conventional example, the electrolyte sometimes overflows from the gap between the electrode group and the liquid inlet at the same time as the electrolyte is injected into the injection tube. The amount of electrolyte injected into the electrode group is 0.01~o
In contrast, in the present invention, the decrease in the amount of electrolyte was less than 0.01.9, and the accuracy of pouring the electrolyte was significantly increased.
また、電解液の飛散がないために、封口部に電解液が接
触せず、注液完了後の封口作業も確実に実施できる。Further, since there is no scattering of the electrolyte, the electrolyte does not come into contact with the sealing portion, and the sealing operation after the completion of injection can be carried out reliably.
