Method for drying electrode pair, method for manufacturing lithium-ion secondary battery, method for manufacturing electric double-layer capacitor, and method for manufacturing lithium-ion capacitor

A method for manufacturing a lithium-ion secondary battery, comprising the steps of:

• 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 the positive electrode, a separator, and the 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 the positive electrode, a separator, and the negative electrode which are laminated in this order;
• accommodating the electrode pair(s) in a container;
• injecting an electrolyte solution into the container in which the electrode pair(s) has been accommodated;
• sealing the container into which the electrolyte solution has been injected;
• and
• drying the container in which the electrode pair(s) has been accommodated by use of a freeze-drying method before the electrolyte solution is injected into the container.
