LITHIUM COMPOSITE OXIDE SINTERED BODY PLATE
Provided is a thick lithium complex oxide sintered plate capable of exhibiting high performance, such as rapid charge performance, when incorporated as a positive electrode in a lithium secondary battery while having high energy density. The lithium complex oxide sintered plate in the present invention comprises a plurality of primary grains having a layered rock-salt structure, the primary grains being bonded, and has a porosity of 3 to 40%, a mean pore diameter of 15 µm or less, an open porosity of 70% or more, and a thickness of 15 to 200 µm. The plurality of primary grains has a primary grain diameter, i.e., a mean diameter of the primary grains, of 20 µm or less and a mean tilt angle of more than 0° to 30° or less. The mean tilt angle is 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.
