Abstract

In order to make a process available for the production of a multi-layer electrode or electrode assembly, with which an electrode or electrode assembly optimized for the respective use may be produced in a simple and, in particular, inexpensive manner it is suggested that a first layer be rolled onto a carrier and at least one additional function layer be produced by spraying on a powder.
