In the present study, it is proposed to achieve the synthesis of bowknot-like CoP microstructures via a facile hydrothermal method combined with a subsequent phosphorylation step. With improved lithium-ion diffusing channels and enhanced conductivity, the novel CoP microstructure is effective in promoting charge transport and maintaining structural integrity during the repeated charge/discharge process. The resulting bowknot-like CoP anode produces a better electrochemical performance, with a specific capacity of 421 mAh center dot g(-1) over 800 cycles at 500 mA center dot g(-1), and a specific capacity of 334 mAh center dot g(-1) at 1000 mA center dot g(-1) with coulombic efficiency of 98.8% after 1000 cycles.
