Facile scalable synthesis and superior lithium storage performance of MoS2-graphite nanocomposites - Journal of Materials Chemistry A (RSC Publishing)
A facile high-energy ball-milling method is developed to synthesize MoS2-graphite (MoS2-C) nanocomposites, which can be used for scalable industrial mass production. As anode material for lithium-ion battery, the obtained MoS2-C composite with 30% C shows a discharge capacity as high as 736 mAh g-1 in the first cycle and retains the capacity up to 720 mAh g-1 after 200 cycles at a current density of 100 mA g-1. Even at a large rate of 2000 mA g-1, the reversible capacity is still 428 mAh g-1. Moreover, a high coulombic efficiency is attained. As carefully compared with MoS2-C composite with 20% C, raw MoS2 and pure ball-milled MoS2, we ascribe the remarkably improved performance in MoS2-C composite with 30% C to the synergistic effects caused by carbon coating and nano-crystallization derived by ball milling.
