Mesoporous Li3VO4/C Submicron‐Ellipsoids Supported on Reduced Graphene Oxide as Practical Anode for High‐Power Lithium‐Ion Batteries
Despite the enormous efforts devoted to high‐performance lithium‐ion batteries (LIBs), the present state‐of‐the‐art LIBs cannot meet the ever‐increasing demands. With high theoretical capacity, fast ionic conductivity, and suitable charge/discharge plateaus, Li3VO4 shows great potential as the anode material for LIBs. However, it suffers from poor electronic conductivity. In this work, we present a novel composite material with mesoporous Li3VO4/C submicron‐ellipsoids supported on rGO (LVO/C/rGO). The synthesized LVO/C/rGO exhibits a high reversible capacity (410 mAh g−1 at 0.25 C), excellent rate capability (230 mAh g−1 at 125 C), and outstanding long‐cycle performance (82.5% capacity retention for 5000 cycles at 10 C). The impressive electrochemical performance reveals the great potential of the mesoporous LVO/C/rGO as a practical anode for high‐power LIBs.
