Abstract
The plate-shaped lithium composite oxide is configured by a plurality of mutually bonded primary particles respectively composed of a lithium composite oxide having a layered rock-salt structure. When fully charged, an expansion-contraction ratio E in a plate face direction parallel to a plate face is less than or equal to 0.5%.
