Abstract

Nitrogen-doped porous carbon is obtained by KOH activation of C<sub>60</sub> in an ammonia atmosphere. As an anode for Li-ion batteries, it shows a reversible capacity of up to ≈1900 mA h g<sup>-1</sup> at 100 mA g<sup>-1</sup> . 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.
