Nitrogen doped porous carbon fibres as anode materials for sodium ion batteries with excellent rate performance.
Nitrogen doped activated porous carbon fibres (ACFs) were prepared as anode materials for Na ion batteries. They exhibit excellent electrochemical performance, especially rate performance. The excellent rate performance is ascribed to the fibre like morphology and the facilitated charge transfer. The influence of nitrogen functionalities on charge transfer and electrochemical performance of N doped carbon anodes for Na ion batteries is discussed.
