1475490 Filling material for tube electrodes for lead batteries VARTA BATTERIE AG 3 March 1976 [7 March 1975] 08545/76 Heading H1B Tube type electrodes containing lead cores for lead storage batteries are filled with a pasty active material comprising a mixture of lead oxides, sulphuric acid and fibres of an electrolyte resistant material so that part of the liquid passes through the tube walls and some of the fibres enter into and cover the pores of the electrode walls to partially close the pores. The pasty active material may comprise 100-600 cc's of water, 5-130 cc's of H 2 SO 4 of density 1À4 grams/cm<SP>3</SP> per kilogram of paste and the fibres may be glass fibre, polyester or polyethylene, may have a rough fissured surface, may be of length 0À5-6 mm and diameter 0À5 Á to 30 Á and may be present in an amount of 0.1 to 2 per cent by wt. based on the weight of lead oxides. |
