PURPOSE:To obtain a cheap electrode which has pliability and increased mechanical-shock resistance by adding a given amount of a conductive material such as carbon black to a thermoplastic, before th mixture is kneaded so as to make the electrode. CONSTITUTION:An electrode 1 used for a secondary zinc-chlorine battery or alkali electrolysis is prepared by adding 20-40wt% of a carbon powder such as carbon black to a thermoplastic such as vinyl chloride or polyethylene, before the mixture is well kneaded and is poured in a metal mold, being followed by subjecting the metal mold filled with the mixture to compression molding. Thus formed electrode 1, inside which a metal net 3 made of a stainless steel or the like is buried, is wrapped in a frame 2 made of the same material as the plastic used for making the electrode 1. By the means mentioned above, the electrode 1 with high mechanical-shock resistance can be obtained at a low cost. Besides, any breakdown of the electrode 1 can be prevented with the frame 2, and the location of the metal net 3 increases the current collecting effect of the electrode 1. |
