Abstract

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.
