PURPOSE:To see that breakdown may not occur at the welded boundary, in the manufacture of the end plate electrode of a zinc-bromine battery where a carbon plastic electrode and an insulating frame are united by welding. CONSTITUTION:An insulating frame is made in advance by injection molding, and a collector brass mesh 13 is put between a plurality of first carbon plastic plates 21a-21d and 21e which have low resistance and are stacked. Together with it, second carbon plastic plates 22a and 22b with high resistance are arranged at the end face of the first carbon plastic plate 21e. An object, where these collector brass mesh 13 and the first and second carbon plastic plates 21a-21e, 22a, and 22b are united by heat press, and an insulating frame, which is made by the said injection molding, are united by vibration welding or thermal plate welding. |
