Document Type and Number:

WIPO Patent Application WO/2016/158566

Kind Code:

A1

Abstract:

Through the present invention, high capacity is realized when lithium manganese phosphate is used as the active material of a lithium ion secondary cell. The present invention is lithium manganese phosphate nanoparticles characterized in that the ratio I20/I29 of the peak intensity at 20° and the peak intensity at 29° thereof obtained by X-ray diffraction is 0.88 to 1.05, and the crystal size thereof obtained by X-ray diffraction is 10 nm to 50 nm.
