Abstract: Provided is a lithium complex oxide sintered plate for use in a positive electrode of a lithium secondary battery. The lithium complex oxide sintered plate has a structure in which a plurality of primary grains having a layered rock-salt structure are 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.

Abstract: A conductivity measurement method of measuring a conductivity of a liquid includes: a) measuring a first complex impedance between a first detection electrode and a second detection electrode at a first frequency with the liquid being in contact with a protective layer to face each of the first detection electrode and the second detection electrode through the protective layer; b) extracting a first extraction value from the first complex impedance according to a predetermined extraction rule; and c) deciding the conductivity of the liquid based on the first extraction value. In the extraction rule, a real part of a complex impedance is considered, and an imaginary part of the complex impedance is ignored.
