BATTERY ELECTRODE AND METHOD FOR PRODUCING SAME

摘要

The aim of the invention is to allow the greatest possible design freedom when selecting an electrode or battery shape, a compact design, and low production costs. This is achieved in that a battery electrode and a method for producing same are provided, wherein a collector substrate is coated with a coating film, and at least one surge protection region is produced on said substrate by ablating the coating film by means of laser ablation.
