Abstract
An electrode for a lithium secondary cell capable of attaining excellent charge/discharge characteristics with high discharge capacity is obtained by properly controlling a component of a collector diffusing into active material layers formed on both sides of the collector. Embodiments include forming a first active material layer consisting of a plurality of layers on a first surface of a collector, and forming a second active material layer consisting of a plurality of layers on a second surface of the collector. At least one layer constituting the second active material layer is formed before forming all layers constituting the first active material layer, thereby preventing heat for forming at least one of the layers constituting the second active material layer from being applied to all layers constituting the first active material layer.
