▎ 摘  要

Improving the rate capability and cycle stability of two-dimensional Molybdenum disulfide (MoS2) still holds the key to its application in lithium-ion batteries (LIBs). Here we reported liquid-exfoliated MoS2 nanosheets/graphene composites (MoS2/Gra) towards the high capacity and excellent cycle stability for LIBs. The composites were assembled by pristine graphene and MoS2 nanosheets, which were prepared via the sonication-assisted liquid exfoliation Of pristine graphite and MoS2 powders in aqueous surfactant solutions. The composites exhibited the reversible capacity as high as 1145 mAh g(-1) after 175 cycles at 100 mA g(-1) and excellent rate capability by retaining similar to 88% of the capacity at 2000 mA g(-1). It is the first time that liquid-exfoliated MoS2/Gra composites show so excellent electrochemical performances and thus are fascinating for LIBs due to the facile, cost-effective and scalable liquid exfoliation route.
