Abstract
Official abstract text for this publication.
An electrode for a secondary battery includes a plurality of active material particles. A length of each of the active material particles in a first direction along a thickness direction of the electrode is larger than a length of the active material particle in a second direction intersecting the first direction.
First claim
Opening claim text (preview).
1 . An electrode for a secondary battery comprising: a plurality of active material particles, wherein a length of each active material particle in a first direction along a thickness direction of the electrode is larger than a length of the active material particle in a second direction intersecting the first direction. 2 . The electrode for the secondary battery according to claim 1 , wherein the plurality of active material particles are hollow inside. 3 . The electrode for the secondary battery according to claim 1 , wherein the plurality of active material particles comprise a crack at a surface. 4 . The electrode for the secondary battery according to claim 2 , wherein an electrolytic solution is contained inside the active material particles. 5 . The electrode for the secondary battery according to claim 2 , wherein the active material particles contain zinc. 6 . The electrode for the secondary battery according to claim 5 , wherein a content of the zinc at both end portions of the electrode along the first direction is larger than a content of the zinc in a central portion of the electrode along the first direction. 7 . The electrode for the secondary battery according to claim 1 , further comprising: a plurality of conductors, wherein a length of each conductor in the first direction is larger than a length of the conductor in the second direction. 8 . The electrode for the secondary battery according to claim 1 , further comprising: a plurality of conductors, wherein a length of each conductor in the first direction is smaller than a length of the conductor in the second direction. 9 . The electrode for the secondary battery according to claim 1 , further comprising: a coating film, the coating film being electrically conductive and covering a surface of the active material particles. 10 . A secondary battery comprising: the electrode for the secondary battery according to claim 1 .
