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.

Claims (22)

1. A method for drying an electrode pair, 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, and

drying the container in which the electrode pair(s) has been accommodated by use of a freeze-drying method before an electrolyte solution is injected into the container.

2. 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.

3. A method for manufacturing an electric double-layer capacitor, 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.
