BATTERY MANUFACTURING METHOD

A method for manufacturing a battery has a stacking step in which a plurality of unit cells are stacked, the unit cells being such that a positive electrode obtained by a positive electrode active material layer containing an electrolytic solution disposed on a positive electrode current collector, and a negative electrode obtained by a negative electrode active material layer containing an electrolytic solution disposed on a negative electrode current collector with a separator interposed therebetween. In the stacking step, each time one of the unit cells is stacked, the stack of the unit cells are pressed from the stacking direction.
