One-dimensional mesoporous CoP nanorods have been successfully synthesized via a facile hydrothermal method and subsequent low temperature thermal phosphorization treatment. At the current density of 500 mA g− 1, CoP nanorods as anode materials for lithium ion batteries deliver a high discharge capacity of 894 mAh g−1 after 300 cycles with a coulombic efficiency over 99%. Even at a high current rate of 4000 mA g-1, the discharge capacity of the CoP electrode can still retain 467 mAh g-1. The results suggest that the introduction of Co element and the special mesoporous nanorods play important roles in enhancing the electrochemical property. Therefore, this rod-like CoP electrode is competent as promising anode materials for high-performance lithium-ion batteries.
