%X Lithium metal oxide nanoparticles were synthesized by induction thermal plasma. Four different systems〞Li每Mn, Li每Cr, Li每Co, and Li每Ni〞were compared to understand formation mechanism of Li每Me oxide nanoparticles in thermal plasma process. Analyses of X-ray diffractometry and electron microscopy showed that Li每Me oxide nanoparticles were successfully synthesized in Li每Mn, Li每Cr, and Li每Co systems. Spinel structured LiMn2O4 with truncated octahedral shape was formed. Layer structured LiCrO2 or LiCoO2 nanoparticles with polyhedral shapes were also synthesized in Li每Cr or Li每Co systems. By contrast, Li每Ni oxide nanoparticles were not synthesized in the Li每Ni system. Nucleation temperatures of each metal in the considered system were evaluated. The relationship between the nucleation temperature and melting and boiling points suggests that the melting points of metal oxides have a strong influence on the formation of lithium metal oxide nanoparticles. A lower melting temperature leads to a longer reaction time, resulting in a higher fraction of the lithium metal oxide nanoparticles in the prepared nanoparticles
