Title: METHOD FOR MANUFACTURING PERFORATED STEEL SHEETS, CORES FOR ELECTRODE PLATES OF SECONDARY CELLS, AND SECONDARY CELL COMPRISING THE CORE
Abstract:
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.
