摘要：

Microporous carbon sheets with precisely controlled thickness, narrow pores, short diffusion paths, high electrical conductive networks, and good wettability are synthesized using very low amounts of graphene sheets as a shape-directing agent via an ionic liquid-assisted surface coating method. When used as the electrode for supercapacitors, the sheets demonstrate excellent rate capability, good cycle stability, high specific capacitance, and high energy/power density.
