Process for manufacturing a button type alkaline battery

Abstract

A method for manufacturing a button-type alkaline cell comprises forming and working a negative electrode having an inner surface of Cu using a die having a ceramic portion while abutting the ceramic portion of the die with at least the Cu inner surface of the negative electrode. The thus formed and worked negative electrode is then combined with a positive electrode compound, a negative electrode compound, a separator, a positive electrode, a gasket and an alkaline electrolyte to form the button-type alkaline cell.
