A connecting piece structure for connecting the plates of an alkaline battery to the battery terminals and a method of welding the connecting piece structure to the plates. The connecting piece is designed to have two slanting surfaces which intersect along a ridge line, the connecting piece having a V-shaped configuration in cross section. The method uses welding electrodes, having bottoms with recessed surfaces which conform to the connecting piece configuration, to weld the connecting piece to the plates.

1. A connecting piece for a battery having positive and negative terminals and having a plate assembly formed by winding or laminating positive and negative plates with a separator interposed therebetween so that the edges of said positive and negative plates partially protrude from opposite end faces of said plate assembly, said connecting piece comprising: at least one current collector disposed across a plurality of said protruding edges, and forming an elongated V-shaped channel having an upper ridge and two lower edges joined by slanting surfaces which together define said V-shape, said two lower edges being welded to said protruding edges so that said lower edges are crosswise engaged with plural protruding edge portions, each said current collector having a free end and a base end, said base ends being joined by a bridging portion; and a lead formed at one end of said at least one current collector for connecting said at least one current collector to one of said positive or negative terminals. 2. A connecting piece for a battery, as claimed in claim 1, wherein said connecting piece comprises two current collectors having ridges which are substantially parallel to one another. 3. A connecting piece for a battery, as claimed in claim 1, wherein said connecting piece comprises two current collectors having ridges which are not parallel to one another. 4. A connecting piece for a battery, as claimed in claim 1, wherein said connecting piece comprises three current collectors having different lengths. 5. A connecting piece for a battery as claimed in claim 4, wherein said ridges of said three current collectors are arranged to form the character "T". 6. A connecting piece for a battery as claimed in claim 4, wherein said ridges of said three current collectors are arranged to form the character "Y". 7. A connecting piece for a battery as claimed in claim 1, wherein said at least one current collector includes an elongated hole extending along said ridge at the intersection of said two slanting surfaces. 8. A connecting piece for a battery as claimed in claim 7, said connecting piece having a substantially circular hole between said lead and each one of said elongated holes. 9. A connecting piece for a battery as claimed in claim 1, wherein said at least one current collector includes an elongated aperture along said upper ridge for receiving a portion of a welding probe.
