ABSTRACT:
A negative electrode for lead accumulators has the form of a rectangular, expanded metal, grid plate 11 of copper. The grid plate serves as carrier for the active mass and for the supply and extraction of current. The direction of stretching of the expanded metal extends parallel to the edge of the rectangular grid plate at which the connection lug is arranged. A lead strip 13, which is in one piece with the connection lug, is conductively secured to the top edge of the grid plate. The lead strip 13 is cast onto the grid plate 11 (FIG. 1).
