PURPOSE:To increase oxygen gas absorbing ability and cycle life by connecting an electrode such as cadmium electrode, which has noble oxygen, to a zinc electrode. CONSTITUTION:The outermost substrate of a zinc electrode is lengthened and coated with paste comprising cadmium oxide powder, metallic cadmium powder, and acetylene black. A cadmium electrode 5 is formed at the edge of the zinc electrode 1 and electrically connected to the zinc electrode. Oxygen gas evolved in a positive electrode is absorbed by the cadmium electrode electrically connected to the zinc electrode, then the cadmium electrode is reduced by the zinc electrode. Therefore, oxygen gas absorbing ability and cycle life are increased. |
