Abstract
A method for producing a composite electrode for a lithium or lithium-ion battery comprises: providing a current collector having a main surface; forming a first electrode layer on the main surface of the current collector, wherein a first adhesion is formed between the current collector and the first electrode layer along the main surface; forming a second electrode layer on the first electrode layer, wherein the first and second electrode layer contact each other along a contact surface opposite the main surface of the current collector, the second electrode layer is adhesively connected to the first electrode layer along the contact surface; and compressing the first and second electrode layer by means of a compression device, wherein, during the compressing, a pressure element of the compression device exerts a pressure on at least one part of the surface of the second electrode layer opposite the contact surface, and a second adhesion can form between the pressure element and the part of the second electrode layer on which the pressure is exerted, wherein the ratio between the first adhesion and the second adhesion resulting from the compression is greater than one.
