Enhanced lithium storage via Fe doping in V2O3/N-doped carbon hybrids: a stable insertion-extraction anode
Abstract:
Fe-doped V2O3 nanoparticles hybridized with N-doped carbon were successfully constructed. The Fe-V2O3/NC anode presents exceptional rate performance in LIBs, achieving a large capacity of 361 mAh g-1 under 5 A g-1. In situ XRD analysis and theoretical calculations collectively elucidated, for the first time, that the Li+ storage mechanism follows an insertion and extraction pathway rather than a conversion reaction.
