Herein, polycrystalline Nb2O5 nanoparticles including pseudo-hexagonal (TT-), orthorhombic (T-), tetragonal (M-) and monoclinic (H-) phases are uniformly anchored onto graphene sheets through a polyol-mediated solvothermal reaction and post heat-treatment, enabling us to discuss the effect of Nb2O5 crystalline phases on Li+ intercalation process. Electrochemical results show that Li+ intercalation...
Herein we report on the hydrothermal synthesis of niobium pentoxide on carbide-derived carbon (Nb2O5/CDC) with a layered structure. The presence of phenylphosphonic acid guides the deposition during preparation, leading to the formation of amorphous Nb2O5 particles which are 4–10 nm in diameter and homogeneously distributed on the CDC framework. Electrochemical testing of the Nb2O5/CDC electrode indicated...
