Title: Multinonmetal-Doped V2O5 Nanocomposites for Lithium-Ion Battery Cathodes

Journal Article · · ACS Applied Energy Materials

Lithium-ion batteries (LIBs) are critical for portable electronics and electric vehicles, demanding higher energy density to meet increasing energy storage needs. Current commercial cathode materials, such as LiFePO4 and LiCoO2, are limited by a single electron transfer, restricting their energy density. Vanadium pentoxide (V2O5) emerges as a promising high-capacity cathode due to its high theoretical capacity of 443 mA h g–1 with three Li storage capacities, significantly surpassing conventional materials. However, the practical application of V2O5 is hindered by a large structural evolution and rapid capacity fading during full lithium intercalation. Here, this study introduces a multinonmetal doping (MNM) strategy to enhance V2O5 cathodes by incorporating all-nonmetal dopants (B, P, and Si) and graphene (G). MNM-V2O5-G exhibits increased surface oxygen defects, improving charge transfer kinetics and thus enhancing the rate performance and cycling stability. Our results provide valuable insights into the role of surface oxygen defects in stabilizing V2O5 with element doping. This research highlights the potential of multinonmetal doping to improve LIB cathode materials, offering a promising pathway for design of high-energy-density V2O5 cathodes and advancing the development of next-generation energy storage solutions.
