The performance of V2O3 is threatened as a result of relatively sluggish electrons/ion transportation andstructural pulverization in lithium-ion batteries. The rational design of the electrode structure to exhibitgreat lithium storage of V2O3 is crucial. In this work, we report stable composite electrodes by integratingV2O3 nanoparticles with an uneven carbon-coated stainless-steel oxide (V2O3/C/SS) current collector viaan in-situ growth method. They allow fast electrical conductivity through the carbon coating and reductionstrategy. Meanwhile, the small nanoparticle size of V2O3 on V2O3/C/SS as well as the undestroyed 3DV–V skeleton are helpful to Li-ion diffusion. The weak interaction between Li ions and V2O3 achieves fastand high Li storage behavior, which proves by electrochemical kinetics analysis and DFT calculation. Theelectrode delivers high rate capacitive and long cycling stability with 564 mAh g1 and 310 mAh g1 at100 mA g1 and 1 A g1, respectively, and a specific capacity of 118 mAh g1 is achieved after 1000 cyclesat 5 A g1. The excellent electrochemical performance may be ascribed to the unique design for effectiveelectron and Li-ion transportation. This work offers a new prospect for the development of highperformancebinder-free V2O3-based electrodes.
