▎ 摘  要

In this work, sulfur-doped graphene nanosheets (SGNS) were fabricated by wet ball milling pristine graphite with carbon disulfide (CS2). With the presence of liquid CS2, pristine graphite was easily infiltrated and exfoliated to graphene nanosheets, and sulfur atom was successfully doped onto the surface of graphene nanosheets. The as-prepared SGNS with sulfur doping content (12.49 wt.%) showed higher reversible specific capacity (588.2 mAh g(-1) and 266.2 mAh g(-1)) than the commercial graphite (240 mAh g(-1) and 69.7 mAh g(-1)) at current densities of 100 and 1000 mA g(-1), respectively. This method described in this study can provide a simple and low-cost strategy for the preparation of SGNS as a promising anode material for lithium-ion batteries.
