のである。As a result, the flow of the electrolyte to the electrolyte outlet (12) tends to be poor, causing stagnation along the way, and it is also necessary to increase the height of the manifold (11). In addition, due to these effects, the movement of the amount of liquid between each divided chamber is also large.
As a result of (a), the energy efficiency of the entire battery is reduced.
0 [Means for Solving the Problems] The present invention has been made in response to such problems, and is provided with a 0 slant on the bottom surface of the electrolyte discharge side manifold A in the upper part of the unit cell. , the slope ranges from 1° to 30°. This allows the electrolyte to flow smoothly, creating an opening that increases the energy efficiency of the battery.
