A method of making an anode, for an electrochemical cell, comprising an anode active ductile metal foil such as lithium and a metal foil substrate. To achieve proper adhesion between the metal foil substrate and the active metal foil the metal foil substrate is impressed with indentations, such as with a knurled roller, either when in contact with the active metal foil (with the anode metal foil being indented as well) or prior thereto. In the latter embodiment the active metal foil is compressed onto the indented metal foil substrate.
