PURPOSE:To make it possible to absorb plenty of electrolyte or water evenly for a short time by forming a deep longitudinal hole of a small bore equal to or smaller than the outer diameter of a carbon rod along the center line of a positive electrode black mix, and pouring the electrolyte or the water on the positive electrode black mix. CONSTITUTION:In the process of processing a positive electrode black mix 1 in a negative electrode zinc can 3, a deep longitudinal hole 4 is formed along the center line of the positive electrode black mix 1. The bore of the hole 4 is made equal to or a little smaller than the outer diameter of a carbon rod 6, and the depth is made to reach almost the lower end of the positive electrode black mix 1. Then an electrolyte 5 is poured on the positive electrode black mix 1 in the negative electrode zinc can 3. As a result, the liquid 5 fills the longitudinal hole 4 of the positive electrode black mix 1, it is accumulated on the upper surface of the black mix 1 at the same time, and absorbed to the black mix 1 after a little while. In such a way, the absorbing speed is increased by the longitudinal hole 4. And since the hole 4 is formed deep in the black mix 1, the liquid is absorbed evenly to the whole black mix 1. |
