摘要：To further improve the capacity, charge rate and cycling stability has become urgent issues to be solved for lithium-ion batteries (LIBs). In our study, we have synthesized nanoporous CoO nanowire clusters on three-dimensional (3D) porous graphene cloth (denoted as CoO-NW@GC) via a facile hydrothermal reaction and subsequent annealing process. The self-supported graphene cloth is provided with large surface area, high porosity and superior electric conductivity, which can greatly contribute to the fast electron and ion transport. Due to the nanoporous CoO nanowire clusters uniformly in situ depositing on the robust 3D skeleton of GC substrate, the CoO-NW@GC hybrid as anode for LIBs achieves 1190 mAh/g and 429 mAh/g under the current densities of 0.2 A/g and 3.2 A/g, respectively. After more than 200 cycles at a current density of 0.5 A/g, the capacity still maintains 1100 mAh/g. The CoO-NW@GC illustrates high specific capacity, good stability as well as excellent rate performance.
