Electrode for battery and its manufacturing method

摘要

In one embodiment of the present inventionManufacturing method of electrode for battery(I) both sides coating region in which the electrode material layer is applied to both surfaces of the current collectorThe process of forming a precursor of said electrode comprising one side coating region adjacent to said double-sided coating region adjacent to one side surface of said collectorAnd (II) the step of pressurizing said precursor of said electrode;Prior to pressurizing the precursor of the electrodeThe current collector located at the boundary between the double coated coating region and the one side coating region is locally subjected to heat treatmentA manufacturing method is provided.
