Abstract
The present invention discloses a method of manufacturing a lithium-ion secondary battery electrode. The method includes the steps of: supplying composite particles (), each containing an active material () and a binder (), onto a sheet collector (); and rolling the composite particles () supplied onto the collector (), thus forming an active material layer (). The rolling step includes a first rolling sub-step involving first rolling, and a second rolling sub-step to be performed after the first rolling sub-step. Rubber rolls (R) are preferably used in the first rolling sub-step.
