    Abstract:
    Owing to the excellent electrical conductivity and high theoretical capacity, binary transition metal sulfides have attracted extensive attention as promising anodes for lithium ion batteries (LIBs). However, the relatively poor electrical conductivity and serious capacity fading originated from large volume change still hinder their practical applications. Herein, binary NiMoS4 nanoparticles are deposited on N doped carbon nanosheets (NC@NiMoS4) through a facile hydrothermal method. The N doped carbon nanosheets and the strong chemical bonding between NC and NiMoS4 can accommodate the volume change, keep the structural integrity and promote the ion/electron transfer during electrochemical reaction. The extra voids between NiMoS4 nanoparticles enlarge the contact area and reduce the lithium migration barriers. As anode for LIBs, the NC@NiMoS4 exhibits the excellent cycle stability with 834 mAh g-1 after 100 cycles at the current density of 100 mA g-1. Even at high rate of 2000 mA g-1, the specific capacity of 544 mAh g-1 can be achieved after 500 cycles.
