Title (EN) METHOD FOR MANUFACTURING PERFORATED STEEL SHEETS, CORES FOR ELECTRODE PLATES OF SECONDARY CELLS, AND SECONDARY CELL COMPRISING THE CORE
(FR) PROCEDE DE FABRICATION DE TOLES EN ACIER PERFOREES, NOYAUX POUR PLAQUES ELECTRODES DE PILES SECONDAIRES, ET PILES SECONDAIRES COMPRENANT UN TEL NOYAU
Abstract: front page image
(EN)A method for manufacturing perforated steel sheets, a method for manufacturing cores for electrode plates of secondary cells, cores, and a secondary cell comprising the core are disclosed. The perforated steel sheet is manufactured by hard-plating a steel sheet, cold-rolling it to crack it, etching it to make many through holes, and rustproofing the surface as required. The perforated steel sheets are suitable for use as the cores of electrode plates of secondary cells.
(FR)Cette invention se rapporte à un procédé servant à la fabrication de tôles d'acier perforées, à un procédé de fabrication de noyaux pour plaques électrodes de piles secondaires, aux noyaux ainsi fabriqués, et à une pile secondaire comprenant un tel noyau. On fabrique cette tôle d'acier perforée en la soumettant à un plaquage dur, en la laminant à froid pour la fendiller, en lui faisant subir une attaque chimique pour y pratiquer de nombreux trous traversants, et en traitant sa surface contre la rouille selon les besoins. Ces tôles d'acier perforées sont aptes à servir de noyaux de plaques électrodes de piles secondaires.
