Abstract: | With the increased demand in energyresources, more and more attentions have been paied to the developing oflithium-ion batteries. The olivine LiFePO4 is consided as the most promising Li-ion battery cathode material ow-ing its high specific capacity, lower cost, environmental friendliness and good thermal stability et al. In this paper, the synthesis methods and modification technology ofLiFePO4,e.g.,high-temperature solid-state-reaction,carbonther-mal reduction, Sol-gel technology, hydrothermal method, Carbon coating method, Metal ion doping and Particle size control,are reviewed and the features of which are also introduced. |
