Japanese Patent JP6483918
Kind Code:
B2
Abstract:
A positive electrode (106) comprises a plurality of mutually bonded primary particles (20) respectively composed of a lithium composite oxide having a layered rock-salt structure. An average orientation angle of the plurality of primary particles (20) relative to a plate face direction that is parallel to a plate face is more than 0° and less than or equal to 30°. In a cross section of the positive electrode (106), the aggregate area of primary particles that have an orientation angle relative to the plate face direction of more than 0° and less than or equal to 30° is greater than or equal to 70% relative to the total area of the plurality of primary particles (20).
