A1
Abstract:
This positive-electrode active material comprises the following: particles that contain a lithium composite oxide; a first layer, containing a lithium composite oxide, provided on the surface of each particle; and a second layer provided on the surface of each first layer. The lithium composite oxide in the particles and the lithium composite oxide in the first layers have the same or nearly the same composition. The second layers contain an oxide or a fluoride. The lithium composite oxide in the first layers exhibits lower crystallinity than the lithium composite oxide in the particles.
