▎ 摘 要
Titanium niobium oxide (TiNb2O7) has shown great potential to replace carbon-based anode materials for lithium-ion batteries because of its high theoretical specific capacity and high rate performance. However, the low intrinsic Li+/e(-) conductivity of TiNb2O7 restricts its extensive application. To overcome this disadvantage, a novel reduced graphene oxide/glucose co-assisted micro titanium niobium oxide hybrid anodes (G/C/TNO) was designed by a bottom-up one-pot method. rGO mainly acted as the carrier to reach the goal of ameliorating electronic conductivity. Glucose, as the fixative and carbon source, chiefly played a protective role in the structural integrity during cycling and synergized with rGO to improve Li+/e(-) transport kinetics. Therefore, the novel G/C/TNO composite displayed a high specific capacity of 208.8 mAh g(-1) at 2C after 500 cycles and a good cycling stability of 161.1 mAh g(-1) at a high rate of 10C in the best case.
