Tailored lithium storage performance of graphene aerogel anodes with controlled surface defects for lithium-ion batteries

- The graphene aerogel (GA) with controllable surface defects was synthesized.
- The graphene aerogel anodes showed high specific capacity and excellent cyclability.
- Surface defects on the GA significantly function for lithium storage.
- This study can extend the application of the graphene anodes for LIBs.
