Zusammenfassung:	1429440 Grids for lead-acid storage cells ESB Inc 16 Oct 1974 [13 Dec 1973] 44857/74 Heading H1B A cylindrical lead-acid storage cell 10 comprises a tubular negative electrode 16, a cylindrical portion of positive active material 22, a tubular separator 20, sulphuric acid electrolyte and a lead containing positive grid 24, the grid having a cylindrical portion and a portion located on a diametric plane embedded in the cylindrical position active material. Negative active material 18 in the form of lead sponge is in electrical contact with the electrode 16 which consists of a lead cup. The positive active material comprises lead peroxide and the cell is surrounded by a moulded plastics container 12 and cover 14. The grid is formed as a cast sheet which is then bent into. an approximately S-shaped cross-section. In a modification the grid comprises an expanded lead sheet which is formed into an E-shaped cross-section and a moulded lead terminal is provided on the grid.
