ELECTROCHEMICAL BATTERY AND ELECTRIC CONTACT FOR FOIL ELECTRODE OF ELECTROCHEMICAL BATTERY

摘要

This invention pertains to an improved means of making electrical and mechanical contact to metal foil electrode in an electrochemical cell. A conductive element is used which has a multiplicity of teeth projecting therefrom. The teeth pierce through the metal foil electrode and are bent over to be flush with the electrode surface. A strong mechanical and electrical bond results.
