A manufacturing method is provided for manufacturing an electrode for a lithium-ion battery having a current collector and an electrode active material layer. In the method, an electrolytic solution is added to particles created by pulverizing a mixture containing electrode active material particles and a pressure sensitive adhesive resin to obtain an electrode active material composition. The electrode active material composition is molded into sheet form on a current collector using a roll press. The electrode active material composition has a weight of the electrolytic solution based on a total weight of the electrode active material composition that is 0.1-50 wt %.

Method for manufacturing electrode for lithium ion battery

A battery manufacturing method includes forming a unit cell having a positive electrode that is obtained by a positive electrode active material layer containing an electrolytic solution being disposed on a positive electrode current collector, a negative electrode that is obtained by a negative electrode active material layer containing an electrolytic solution being disposed on a negative electrode current collector, and a separator interposed between the positive electrode and the negative electrode. The battery manufacturing method further includes applying pressure to one unit cell or with two or more stacked unit cells from the stacking direction, and charging the one unit cell or the two or more stacked unit cells after applying of the pressure. The method is performed such that the positive electrode and the negative electrode are formed without an application film being subjected to a drying process performed through heating.
