The EuVO4-V2O5 composite nanowire with plum blossom structure is prepared by hydrothermal method, cation-exchange and calci-nation method. The EuVO4-V2O5 nanowire electrode materials are calcined at 300 and 500 oC, respectively. The results show that as the temperature continued to increase, the nanoparticles on the surface of the EuVO4-V2O5 nanowires has a certain agglomeration. When the temperature increased to 500 oC, the nanowires melted. Among them, the EuVO4-V2O5 composite nanowire prepared by calcination at 300 oC has the best electrochemical performance, and the charge-discharge specific capacity remains 376 mAh g-1 after 50 cycles with a current density of 30 mA g-1, showing good cycle stability, and this article developed a new synthetic route of rare earth vanadate.
