摘要：以异丙醇/水、氟化石墨分别作试剂和原料,采用液相剥离法制备出氟化石墨烯。所制氟化石墨烯呈二维、无定型的多孔结构,其中F含量高达49.7%。氟化石墨烯丰富的C-F键及其超薄的二维纳米结构有利于Li+在充放电过程中的存储和扩散,因此所制氟化石墨烯具有优异的电化学性能,尤其有较大的功率密度。
A free-standing fluorinated graphene（F-graphene） was fabricated by the simple liquid exfoliation of a fluorinated graphite（F-graphite） in a 2-propanol/water mixture,and was used as the cathode material of primary lithium ion batteries.As-prepared F-grapheneh as a very high fluorine content（49.7 at%）,and an amorphous-like two-dimensional nanostructure.These features facilitate the rapid diffusion of lithium ions during discharging.The F-graphene exhibits better electrochemical performance,especially,a higher specific power density than the F-graphite.
