Abstract: Highly conductive Ag is proven effective to improve the electrochemical performance of Li3VO4. Ag@Li3VO4 composite with unique architecture of Ag nanoparticles embedded homogeneously in Li3VO4 matrix is prepared by a facile intermediate solution method. The Ag@Li3VO4 delivers high initial discharge and charge capacities of 651 and 479 mAh g−1 at a specific current of 0.15 A g−1, maintaining of 498 and 492 mAh g−1 after 150 cycles. Superior rate capability (364 mAh g−1) can be achieved at 1.5 A g−1, with more than 5 times improvement compared the one without Ag decoration. Herein, conductive but inert Ag is found facilitating fast Li+ ion storage of the Li3VO4 owing to enhanced electronic conductivity, Li ion diffusion, and structure stability, distinctly improving cycle stability and rate performance.
