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 and negative electrodes. Heat sealing a seal part that is disposed at an outer peripheral portion of the unit cell. Cooling the outer peripheral portion of the unit cell by using a cooling medium after carrying out the heat sealing of the seal part. 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.
