電気化学電池用の電極、その製造方法及びそれを利用した電気化学電池

Japanese Patent JP5484164

B2

An electrode for an electrochemical cell is provided. The electrode comprises an electrode active material coated on a current collector. The surface of the electrode active material has a greater porosity than the portion nearest the current collector. The electrode includes an active material with controlled porosity, where the porosity of the inner portion is equal to or less than the porosity of the surface of the electrode after the electrode is roll-pressed. As a result, the impregnating characteristics of the electrolytic solution are improved and decreases in capacity upon charging and discharging at high rates are prevented. Therefore, excellent charge and discharge characteristics are obtained. In addition, cells including the inventive electrodes exhibit excellent charge and discharge characteristics.
