Title:
ELECTRODE, ELECTRICITY STORAGE DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2015118930
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: an electricity storage device high in capacity per volume or weight; an electricity storage device high in energy density; an electricity storage device high in reliability; an electricity storage device long in service life; an electrode for an electricity storage device suppressed in deterioration due to deformation; and a strong electrode for an electricity storage device high in strength against deformation.SOLUTION: An electrode is covered with a first insulator. The first insulator has a bag-like or cylindrical shape. The electrode has an active material and a first film. At least a part of the active material is covered with the first film. The first film allows carrier ions in an electrolyte to pass therethrough and dose not allow a solvent of the electrolyte to pass therethrough.
