LITHIUM MANGANESE PHOSPHATE NANOPARTICLES AND METHOD FOR MANUFACTURING SAME, CARBON-COATED LITHIUM MANGANESE PHOSPHATE NANOPARTICLES, CARBON-COATED LITHIUM MANGANESE PHOSPHATE NANOPARTICLE GRANULATED BODY, AND LITHIUM ION CELL

摘要

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.
