中文摘要	The (1-x)LiMnPO4 center dot LixTix(PO4)(delta) (x=0, 0.01, 0.05, 0.10, 0.15, 0.20) cathode materials are successfully synthesized through a solid-state method. The structures and electrochemical properties of the prepared samples have been characterized comprehensively. It is found minority phases containing LiTi2(PO4)(3) and TiP2O7 were formed. The addition of Ti has obviously reduced the size of grains. Electrochemical tests indicate that the discharge capacities of LiMnPO4 samples can be significantly improved with the addition of Ti. Especially, the (1-x)LiMnPO4 center dot LixTi(PO4)(delta) sample with x=0.1 has the largest discharge specific capacity, which is more than 131 mAh g(-1) at 0.05 C. And EIS tests' demonstrate that the 0.9LiMnPO(4)center dot Li0.1Ti0.1(PO4)(delta) sample has lower charge transfer resistance and higher diffusion coefficient than the pristine LiMnPO4 sample.
