1. A method for manufacturing an electrode for a lithium-ion battery having a current collector and an electrode active material layer, the method comprising:
forming the electrode by molding an electrode active material composition containing electrode active material particles and an electrolytic solution into sheet form using a roll press such that opposite surfaces of the electrode active material composition are each in contact with rolls of the roll press, discharging the electrode active material composition in sheet form vertically or horizontally away from the rolls and layering the electrode active material composition formed into sheet form onto a surface of the current collector after the electrode active material composition has been discharged from the rolls to form the electrode active material layer,
a weight of the electrolytic solution based on a total weight of the electrode active material composition being 0.1-50 wt %, and
the method not including a step of drying or heating when forming the electrode active material layer.
