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.

Silicon has demonstrated inordinate potential as anode material for next-generation lithium-ion batteries due to its high theoretical specific capacity. Nevertheless, the structural dilapidation during the lithiation/delithiation process has restricted its large-scope application. To conquer these challenges, we design a novel reduced graphene oxide (rGO)-coated Si@SiO x @β-Bi 2 O 3 /Bi composite by a facile one-pot method. The Bi 2 O 3 shell chiefly guarantees the structural integrity of Si-core during cyclings and synergizes with Bi nanodots to expediting Li+/e− transport kinetics. rGO mainly acts as the carrier to attaining the twofold goals of ameliorating the electronic conductivity and cushioning the stress from volume expansion. Therefore, the novel rGO-coated Si@SiO x @β-Bi 2 O 3 /Bi composite exhibits a high specific capacity of 1784 mAh g−1 at 1 A g−1 after 200 cycles and a good cycling stability of 1007 mAh g−1 at a high rate of 4 A g−1.
