Assisted by graphene oxide(GO),nano-sized LiMn_(0.6)Fe_(0.4)PO_4 with excellent electrochemical performance was prepared by a facile hydrothermal method as cathode material for lithium ion battery.SEM and TEM images indicate that the particle size of LiMn_(0.6)Fe_(0.4)PO_4(S2)was about 80 nm in diameter.The discharge capacity of LiMn_(0.6)Fe_(0.4)PO_4 nanoparticles was 140.3 mAh-g^1 in the first cycle.It showed that graphene oxide was able to restrict the growth of LiMn_(0.6)Fe_(0.4)PO_4 and it in situ reduction of GO could improve the electrical conductivity of LiMn_(0.6)Fe_(0.4)PO_4 material.
