METHOD OF MANUFACTURING ELECTRICAL ENERGY STORAGE DEVICE

Title:

METHOD OF MANUFACTURING ELECTRICAL ENERGY STORAGE DEVICE

Document Type and Number:

Japanese Patent JP3813455

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an electrode material having satisfactory wettability to electrolyte and a binding property which is hardly impaired, even if brought into contact with the electrolyte in an electrical energy storage device, in which an electrode is formed by using an electrode material including electrode active material, conductive agent, and a binder and an electrolyte is impregnated in the electrode.
SOLUTION: This manufacturing method comprises a step of manufacturing a first composite particle body having first binder 21, provided between the electrode active material and/or conductive agent particles 1 by kneading the electrode active material, conductive agent, and first binder; and a second composite particle body manufacturing step for manufacturing a second composite particle body, having the first binder 21 and/or a second binder 22 provided between the electrode active material and/or conductive agent particles 1, by charging and kneading the first composite particle body in a solution obtained by making the second binder dissolved, which is formed of a material with hydrophilic and lipophilic properties stronger than the first binder. The second composite particle body is used as the electrode material of an electrical energy storage device.
