Research progress on lithium iron phosphate as lithium ion battery cathode material

The synthetic methods of lithium iron phosphate as lithium ion battery cathode material were introduced briefly.The fundamental process,improvement,merits,demerits of solid-phase synthesis were presented first,then the basic theory and research of liquid-phase synthesis including hydrothermal process,sol-gel process and co-precipitation process were introduced.And then modification status for lithium iron phosphate was described from crystal doping and non-crystal doping.The development trend of lithium iron phosphate was prospected at last.
