MANUFACTURING METHOD OF ELECTRODE, MANUFACTURING DEVICE OF ELECTRODE USED IN MANUFACTURING METHOD, AND BATTERY MANUFACTURED BY ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode capable of improving overcharge characteristics while suppressing deterioration of battery performance in normal charge and discharge due to increase of internal resistance of the electrode, and capable of suppressing occurrence of slippage of the active materials and deterioration of adhesion of the active materials or increase of manufacturing cost, and a manufacturing device of the electrode used in its manufacturing method.

SOLUTION: This is a manufacturing method of an electrode in which two active material layers 2, 3 are formed on the surface of a current collector 1 by lamination coating in order a plurality of active material slurry having different kinds of active materials and containing a binder component. The above plurality of active material slurry are lamination coated in order on the surface of the current collector in wet state and thereafter, all of the active material slurry are dried.
