Red phosphorus nanoparticles embedded in porous N-doped carbon nanofibers as high-performance anode for sodium-ion batteries

Red phosphorus nanoparticles are homogeneously encapsulated in porous N-doped carbon nanofibers through shear emulsifying and electrospinning processes. The as-prepared P@C nanofibers with free-standing membrane is directly used as binder- and current collector-free anode for Na-ion batteries, exhibiting fascinating electrochemical performance in terms of exceptional rate capability, ultra-long cycling life, and high energy density.432
