MULTI LAYERED ELECTRODE AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed are an electrode for secondary batteries including an electrode mixture coated on one surface or opposite surface of an electrode current collector, and a method of manufacturing the same. The electrode mixture includes an electrode mixture layer A, which is a portion close to a current collector, and an electrode mixture layer, which is a portion distant from a current collector. The electrode mixture layer A includes a mixture of two active materials, average diameters of which are different, and the electrode mixture layer B includes active materials, average diameters of which are the same.
