Synthesis and characterization of LiMnBO3 cathode material for lithium ion batteries

LiMnBO3 with enhanced powder density was successfully synthesized by a commercially available spray-drying process. A monoclinic-LiMnBO3 single phase was experimentally substantiated by an X-ray diffractometer with crystallinity investigated by Rietveld refinement method (Bragg R-factor and RF-factor <10). The dense LiMnBO3 powder prepared by the spray drying process showed spherical morphology. The electrochemical property of LiMnBO3 was extensively investigated, positively revealing that 0.27 Li+ (Li0.27MnBO3) was stoichiometrically extracted from the host LiMnBO3 material at first cycle.
