“…In addition, some methods are proposed to further enhance the conductivity of TiO 2 . For example, the combination of carbon nanotubes, graphite, and other conductive additives is used to form some composite materials [ 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. Although these conductive additives can effectively improve the electron transport rate on the surface of the particles, they still suffer from low conductivity in TiO 2 .…”

TiO2 is a promising anode material for lithium-ion batteries (LIBs) due to its low cost, suitable operating voltage, and excellent structural stability. The inherent poor electron conductivity and low ion diffusion coefficient, however, severely limit its application in lithium storage. Here, Co-doped TiO2 is synthesized by a hydrothermal method as an anode material since Co@TiO2 possesses a large specific surface area and high electronic conductivity. Thanks to the Co dopants, the ion diffusion and electron transport are both greatly improved, which is very beneficial for cycle stability, coulombic efficiency (CE), reversible capacity, and rate performance. As a result, Co@TiO2 shows a high reversible capacity of 227 mAh g−1 at 3 C, excellent rate performance, and cycling stability with a capacity of about 125 mAh g−1 at 10C after 600 cycles (1 C = 170 mA g−1).
