Titanium niobium oxide (TiNb2O7) has been known as a potential candidate for the “zero-strain” material Li4Ti5O12 for power lithium ion battery, but its wide band gap energy (Eg ∼ 2.0 eV), which representing low electronic conductivity, limits its application. Here, by adjusting the ratio of raw material TiO2 and Nb2O5, a series of Ti1-xNb2+xO7 (x = 0, 0.01, 0.02, 0.04, 0.06) were prepared via a high...
