Abstract
Electrodes having at least one current correcting layer between the current collector and the separator drive electron flow in a direction perpendicular to the X-Y plane. Such an electrode includes a current collector, a first active material layer coated on the current collector, a first current correcting layer on the first active material layer opposite the current collector and a second active material layer on the first current correcting layer opposite the first active material layer. The first current correcting layer is a highly conductive, porous material that is not electrochemically active, the first current correcting layer being uniformly formed along an X-Y plane of the electrode.
