Abstract:
The olivine structured mixed lithium-transition metal phosphates LiMPO4 (M = Fe, Mn, Co) have attracted
tremendous attention of many research teams worldwide as a promising cathode materials for lithium batteries. Among
them, lithium manganese phosphate LiMnPO4 is the most promising considering its high theoretical capacity and
operating voltage, low cost and environmental safety. Various techniques were applied to prepare this perspective cathode
for lithium batteries. The solution based synthetic routes such as spray pyrolysis, precipitation, sol-gel, hydrothermal and
polyol synthesis allow preparing nanostructured powders of LiMnPO4 with enhanced electrochemical properties, which is
mostly attributed to the higher chemical homogeneity and narrow particle size distribution of the material. Up-to-date, the
LiMnPO4/C composites prepared by the spray pyrolysis route have the best electrochemical performance among the
reported in the literature.
