Studies on Li-Mn-O spinel system (obtained from melt-impregnation method) as a cathode for 4 V lithium batteries -Part V. Enhancement of the elevated temperature performance of Li/LiMn2O4 cells

Stoichiometric LiMn2O4, metal-ion doped (Li+ and Co3+) spinels, Li1-xMn2-x-yMyO4, and fluorine substituted spinel, Li1-xMn2O4-zFz, are examined as cathodes in Li/organic electrolyte/LixMn2O4 cells containing various electrolytes at both room temperature and 50 degrees C. The elevated temperature performance is improved with the metal-ion doped and fluorine substituted spinels in LiBF4 base electrolyte solution.
