Title: LITHIUM MANGANESE PHOSPHATE NANOPARTICLES AND METHOD FOR PRODUCING SAME, CARBON-COATED LITHIUM MANGANESE PHOSPHATE NANOPARTICLES, CARBON-COATED LITHIUM MANGANESE PHOSPHATE NANOPARTICLE GRANULE, AND LITHIUM ION BATTERY
Abstract:
The present invention achieves high capacity when lithium manganese phosphate is used as an active material for lithium ion batteries. The present invention provides lithium manganese phosphate nanoparticles which are characterized by having: a ratio, I20/I29, of a peak intensity at 20º to a peak intensity at 29º obtained by X-ray diffraction of 0.88 to 1.05; and a crystallite size obtained by X-ray diffraction of 10 to 50 nm.
