Superior sodium storage in phosphorus@porous multichannel flexible freestanding carbon nanofibers

Phosphorus@porous multichannel carbon nanofibers (PMCNFs) are obtained by confining nanosized amorphous red phosphorus into porous multichannel flexible freestanding carbon nanofibers. The phosphorus@PMCNFs displays enhanced electrochemical performance as anodes for sodium-ion batteries (NIBs) because the special nanostructure could accommodate the huge volume change of phosphorus and improve the electronic conductivity of phosphorus.147
