Modification of volume expansion and poor conductivity of ternary metal molybdates as an anode for lithium-ion batteries (LIBs) results in the improvement of their reversibility and rate capability. Herein, porous rod-like cobalt molybdate incorporated with nitrogen (N) doped reduced graphene oxide (rGO) was fabricated using a silicone oil-bath method and further heated at 500 degrees C (designated as CMO500@N-G) and 600 degrees C (CMO600@N-G). The well-designed CMO500@N-G and CMO600@N-G electrodes were explored as an anode for LIBs. Notably, the CMO500@N-G electrode exhibited a discharge capacity of 612 mA h g(-1) over 250 cycles at 100 mA g(-1), while the CMO600@N-G was restricted to 199.5 mA h g(-1). Besides, the CMO500@N-G electrode was sustained for 2000 cycles with a remarkable discharge capacity of 665 mA h g(-1) even at a high current density of 1000 mA g(-1). Finally, using a newly developed CMO500@N-G anode, a full cell LIB was also fabricated and showed good reversibility and excellent rate performance. This outstanding performance of the electrode can be ascribed to the unique rod-like morphology of cobalt molybdate with a highly conductive N doped rGO, which suggests a new strategy to fabricate high-capacity anode materials for LIBs.
