- •
Ultrasmall Sn nanoparticles are decorated in situ on crumpled N-doped graphene.
- •
Sn@NG shows high dispersion of Sn and large pore volume.
- •
The effects of Sn loading step, treatment temperature and N-doping are studied.
- •
Sn@NG demonstrates excellent long-term cycle stability at high current rates.
