摘要： The present invention provides an electrode for batteries, especially a pasted electrode, and a process for producing the same which is improved in the adhesiveness between the active material and the electrode core material, utilization of the active material, discharge characteristics and in the charge and discharge cycling life. The resultant electroconductive core material comprises a perforated or non-perforated metal sheet such as punched metal sheet having sintered hollow nickel members separately or entangled fixed on the surfaces thereof. The hollow of the sintered nickel members is formed due to the thermal decomposition and evaporation of the resin fibers which have been applied to the electroconductive core material.
