High-performance anode materials for lithium ion batteries are required due to their increased applications in portable electronic devices and electronic vehicles. In this work, crumpled MoS2/N-doped carbon nanocomposites were synthesized via a simple solventless method. The nanocomposites were identified as homogenously distributed MoS2 in N-doped carbon matrix. The nanocomposites provide the morphological advantages of 3D interconnected electron pathways and an enlarged ionic contact area for improving electrochemical performance when they were used as anodes for lithium ion batteries. Furthermore, the N-doped carbon matrix could enhance electrical conductivity as well as suppressing volume changes during cycling. The nanocomposites demonstrated a reversible discharge capacity of 264 mAh g-1 at 10 A g-1 and a stable cycle life with a discharge capacity of 324.2 mAh g-1 and coulombic efficiency of 99.7%, even after the 1000th cycle at 4 A g-1. These results indicate that the nanocomposites offer great potential as anode materials for lithium ion batteries.
