Abstract

A positive electrode is configured by plurality of mutually bonded primary particles respectively composed of a lithium composite oxide having a layered rock-salt structure. An average orientation angle of the plurality of primary particles relative to a plate face direction parallel to a plate face is more than 0° and less than or equal to 30°. An aggregate surface area of primary particles that have an aspect ratio of greater than or equal to 4 is greater than or equal to 70% relative to a total area of the plurality of primary particles, in cross section.
