Abstract
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.
