Abstract

Nitrogen-doped porous carbon is obtained by KOH activation of C₆₀ in an ammonia atmosphere. As an anode for Li-ion batteries, it shows a reversible capacity of up to ≈1900 mA h g^-1 at 100 mA g^-1 . Simulations suggest that the superior Li-ion storage may be related to the curvature of the graphenes and the presence of pyrrolic/pyridinic group dopants.

Keywords: KOH activation; Li-ion batteries; fullerene; graphene; supercapacitors, porous carbon.
