PURPOSE:To suppress the growth of resinoid zinc so as to aim at enhancement of cyclic characteristics of the storage battery in the caption, by laying a calcium hydroxide layer made of calcium hydroxide with specific particle size on the surface of a zinc pole, as well as specifying the particle size of calcium oxide added to the inside of the zinc pole. CONSTITUTION:A calcium hydroxide layer made of calcium hydroxide with 50-300mum particle size is laid on the surface of a zinc pole as well as calcium hydroxide with 50-300mum particle size is added to the inside of the zinc pole. Owing the synergistic effect caused by these materials, fixation of zincic acid ion rendered out of a zinc pole and derioration of electrolytic dispersion into the inside of the zinc pole depending upon densificaiton of zincic acid calcium can be very efficiently suppressed. Therefore, an excellent cyclic characteristic can be exhibited for a long period. |
