Abstract:
A method for producing an electrode having an electrically conductive current collector layer having a terminal region for connection to an electrical power circuit, in which to improve the electrical discharge via the terminal region, the current collector layer has at least one structural element having an electrical conductivity that is increased compared to the current collector layer, through which structural element the electrical resistance between a point on the current collector layer and the terminal region is reduced, the method including: providing at least one free-standing active material foil; providing an electrically conductive layer on at least one surface of the active material foil, the electrically conductive layer being formed immediately on the surface of the active material foil to form the current collector layer; and connecting an electrical terminal region to the electrically conductive layer to enable connection to an electrical power circuit.
