Physicochemical Properties of Ag-doped Li3VO4 as Anode Material for Mithium Ion Batteries

In this work, Li₃VO₄ (LVO) and silver-doped Li₃VO₄ (LVO-Ag) samples have been synthesized via the solgel method and followed with calcinations for their uses as anode materials for lithium ion battery LIBs. The synthesized samples were characterized by XRD, SEM, and CV tests. XRD results showed that the Ag⁺ doping into Li₃VO₄ can lead to lattice micro expansion which favors the intercalation and deintercalation of the Li ions. The SEM characterization displayed that LVO-Ag has a good morphology with a uniform and smaller particle size than that of LVO. The CV measurements demonstrate that Ag doped Li₃VO₄ samples exhibit enhanced electrochemical performance compared to undoped LVO. Therefore, the LVO-Ag sample could serve as a promising anode material for high performance LIBs.
