Abstract of Disclosure: A negative electrode for lead accumulators has the shape of a rectangular planar grid plate (11) consisting of expanded copper metal which serves as a carrier for the active mass and for the supply and extraction of current. The grid plate (11) consists of two side regions of expanded copper metal (14) and a copper strip (12) which is arranged between them in one piece therewith, and which projects at one end beyond the regions of expanded copper metal in order to form the connection lug (13). A current conducting strip is formed at the upper edge of the regions (14) of the expanded metal grid by the appropriately cut-off the webs (15) which are bent towards one another into mutual contact at the edge (16) of the expanded copper metal regions (14) at the connection lug side.
