N-doped MoS₂ Nano-Flowers as High-Performance Anode Electrode for Excellent Lithium Storage

摘要

N-doped MoS 2 nano-flowers are successfully synthesized and used as the anode materials for thelithium-ion batteries. The electronic conductivity of the MoS 2 anode materials could be effectivelyimproved by the nitrogen doping process. Compared with the pristine MoS 2 anode electrodes, the N-doped MoS 2 anode electrodes exhibit specific capacity value of 786 mAh g -1 after 100 cycles at thehigh current density of 0.5 C, demonstrating excellent cycle stability. This stable cycle performance isascribed to the superior electronic conductivity of the N-doped MoS 2 anode, which could providepathways for the transport of the electronics.
