Lithium cobalt oxide (LiCoO2) with layered structure is the earliest found and widely employed cathode material for Li ion batteries (LIBs) due to its excellent cycling stability.Though its theoretical capacity is around 274 mAh g-1,the practical capacity can only achieve to ~140 mAh g-1 when charged to 4.2 V (vs.Li/Li+),corresponding to de-intercalation of 0.5 Li per LiCoO2 [1].

橄榄石型结构的LiFePO4材料虽然具有环境友好、结构稳定的优点,但是其材料的电子电导率较低,约为10-9~10-10s·cm-1[1],锂离子在磷酸铁锂中的扩散系数为10-14-10-16m2·s-1[2].受制于极低的电子电导率和离子扩散系数,LiFePO4正极材料在高倍率条件下的性能较差,因此,提高LiFePO4正极材料的电导率和离子传输速率,改善LiFePO4正极材料的倍率性能是影响LiF
