    Effect of calcination temperature on electrochemical performance of niobium oxides/carbon composites

    Orthorhombic niobium pentoxide (T-Nb2O5) possesses an intercalation pseudocapacitive behavior, which is a promising candidate of high-rate anodes for Li-ion capacitors. However, its low electric conductivity hind...
