MANUFACTURING PROCESS AND APPARATUS FOR ELECTRICALLY INSULATING LAYERS OF ELECTROCHEMICAL CELL LAMINATES

摘要

A manufacturing process and an apparatus to carry out the process are disclosed which eliminate or at least significantly reduce the occurrence of damaging localized short circuits in the production of electrochemical generators. The process and apparatus include cauterization by oxidation of the anode edges of multiple electrochemical cell laminates thereby rendering the anode edges electrically insulated from adjacent cathodes and/or current collectors.
