Abstract
AbstractThe molybdenum sulfide has a layered structure, similar to graphite, and delivers a good transfer channel for lithium ions as an anode. To enhance the discharge capacity and cycling stability of the molybdenum sulfide, exfoliated MoS2 nanoflakes with a N‐doped carbon coating were prepared by exfoliation of bulk MoS2 and carbonization of a polydopamine coating. The morphological characteristics show that the carbonized polydopamine was coated on the surface of MoS2 nanoflakes successfully. Consequently, as‐prepared E‐MoS2@NC delivers a good electrochemical performance and cycling stability as the anode for lithium‐ion batteries; the reversible lithium storage capacity was up to 650 mAh g−1 at a current density of 0.2 A g−1, and the discharge specific capacity was stabilized at 562 mAh g−1 even after 200 cycles at a current density of 0.5 A g−1.
