ANHYDRIDE OF LITHIUM HYDROXIDE FOR MANUFACTURING LITHIUM TRANSITION METAL COMPLEX OXIDE AND ITS MANUFACTURING METHOD, AND METHOD FOR MANUFACTURING LITHIUM TRANSITION METAL COMPLEX OXIDE USING IT

摘要

PPROBLEM TO BE SOLVED: To provide a method for effectively producing a lithium transition metal complex oxide having an excellent resistance characteristic when used as a positive electrode active material of a lithium secondary battery. PSOLUTION: The anhydride of lithium hydroxide for manufacturing a lithium transition metal complex oxide is specified to have the maximum particle diameter of 40 m when its particle size distribution is measured by a laser diffraction method using a real part of 1.14 and an imaginary part of 0.00 as a refractive index, where the specimen for measurement is prepared by supplying the anhydride of lithium hydroxide into an ethyl alcohol solution saturated with lithium hydroxide to have a light transmittance of 805% when measured by the laser diffraction and dispersing for 1 minute by an ultrasonic oscillator at an output of 30 W and a frequency of 22.5 kHz.
