英文摘要：

LiFePO4 Li-ion battery can meet the requirements of electric vehicles. As the positive material, LiFePO4 has great prospects in the application to Li-ion battery. The research progress on doping modification of LiFePO4 positive material for Li-ion battery was introduced in this paper. And the possible problems and solutions of modification of non-lattice doping, lattice doping and mix-doping were discussed.
