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

Abstract

N-doped MoS2 nano-flowers are successfully synthesized and used as the anode materials for the lithium-ion batteries. The electronic conductivity of the MoS2 anode materials could be effectively improved by the nitrogen doping process. Compared with the pristine MoS2 anode electrodes, the N- doped MoS2 anode electrodes exhibit specific capacity value of 786 mAh g-1 after 100 cycles at the high current density of 0.5 C, demonstrating excellent cycle stability. This stable cycle performance is ascribed to the superior electronic conductivity of the N-doped MoS2 anode, which could provide pathways for the transport of the electronics.
