Abstract
A method for manufacturing a lithium ion secondary battery having electrodes in which a mix layer including a first binder and one of a positive electrode active material and a negative electrode active material is formed via a second binder on a collector. The method includes: performing pattern coating of the second binder on the surface of the collector and regularly forming binder-coated sections and uncoated sections; and feeding a powder of mix particles on the binder-coated sections and the uncoated sections so as to form the mix layer on the collector.
