リチウムイオン二次電池用電極、及びリチウムイオン二次電池

Document Type and Number:

Japanese Patent JP7177210

Kind Code:

B2

Abstract:

This lithium-ion secondary battery electrode 10 is provided with: a current collector; a first electrode active material layer 12 disposed on one surface of the current collector; and a first insulating layer 13 disposed on the first electrode active material layer 12. The current collector has an end 11A that is not covered by the first electrode active material layer 12. At said end 11A of the current collector, an end 13A of the first insulating layer 13 protrudes from the first electrode active material layer 12 so as to cover a portion of the end 11A of the current collector, and has a wavy shape in which a plurality of thin and long protrusions 13X are formed in parallel. The respective protrusions 13X have a length D of not more than 5 mm.
