Nitrogen-doped graphene aerogels as anode materials for lithium-ion battery: Assembly and electrochemical properties

Three-dimensional nitrogen-doped graphene aerogel (N-GA) is facilely synthesized via a hydrothermal method combined with freeze drying. When it is used as an anode for lithium-ion battery, N-GA possesses larger surface area (SBET=379.1m2g−1), higher reversible capacity (535.3mAhg−1 in the 100th cycl...

Description
Summary:Three-dimensional nitrogen-doped graphene aerogel (N-GA) is facilely synthesized via a hydrothermal method combined with freeze drying. When it is used as an anode for lithium-ion battery, N-GA possesses larger surface area (SBET=379.1m2g−1), higher reversible capacity (535.3mAhg−1 in the 100th cycle ) and more stable cycling performance compared with those of pristine GA, which could result from the structural defects caused by the nitrogen doping. [Display omitted] •3D N-GA was assembled with ammonia and GO derived from the puffing graphite powders.•The electrochemical properties of GA and N-GA were investigated for LIBs.•N-GA was approved to be a promising candidate as anode material in LIBs.
