Zusammenfassung:A method of forming anodes for electrochemical devices by laminating a metal foil to a current collector and creating anode-active-material patches, composed of the metal foil, that are spaced from one another by inter-patch regions, wherein each inter-patch region provides a location for forming one or more electrical tabs of the finished anodes. The method can further include applying conductive-coating patches to the current collector prior to laminating the metal foil to the current collector, wherein each conductive-coating patch corresponds to one of the anode-active-material patches. In some embodiments, the conductive-coating patches can assist with forming the anode- active-material patches and/or can improve the cycling performance of an electrochemical device made using anodes made therewith. Anodes containing anode-active material and conductive coatings applied to current collectors are also disclosed.
