Researchers have shown electrochemical Li insertion and deinsertion property of Ti-Nb mixed oxide Ti2Nb10O29 (TNO) at high current rate is greatly improved by vacuum annealing. This is mainly attributed to enhancement of intrinsic electronic conductivity of TNO by introducing oxygen vacancy. Vacuum-annealed TNO is promising negative electrode material of high power and high safety Li-ion battery for large scale application.
