Abstract
Disclosed is a lithium complex oxide sintered plate including a plurality of primary grains having a layered rock-salt structure, the primary grains being bonded. The lithium complex oxide has a composition represented by the formula: Li(CoM)O(wherein, 1.0≤x≤1.1, 0<y≤0.1, 0≤δ<1, and M is at least one selected from the group consisting of Mg, Ni, Al, and Mn), and the primary grains have a mean tilt angle of more than 0° to 30° or less, the mean tilt angle being a mean value of the angles defined by the (003) planes of the primary grains and the plate face of the lithium complex oxide sintered plate.
