Abstract
A method for drying an electrode pair is disclosed. In at least one embodiment, the method includes preparing a positive electrode by applying a positive electrode material to a current collector; preparing a negative electrode by applying a negative electrode material to a current collector; preparing one set of an electrode pair made up of a positive electrode, a separator, and a negative electrode which are laminated in this order or preparing sets of electrode pairs, the sets being laminated, a separator being provided between the respective sets, each of the electrode pairs being made up of a positive electrode, a separator, and a negative electrode which are laminated in this order; accommodating the electrode pair(s) in a container; and drying the container in which the electrode pair(s) has been accommodated by use of the freeze-drying method.
