原始语种摘要: Abstract(#br)Phosphorus is considered as a promising anode for Na-ion battery because of its high theoretical capacity of 2595mAhg −1 . In this study, two phosphorus-carbon (P-C) composites with well-controlled compositions and nanostructures of P and C have been developed: P@YP composite with P confined within porous structure of YP-80F carbon and P@CNT with unconfined P deposited on the surface of carbon nanotube. The structure and electrochemical performance of these two composites have been studied to illustrate the effect of nanostructures of both C and P. P@YP composite with appropriate amount of P confined in nanopores can accommodate its large volume change upon sodiation/desodiation and enable a stable solid-electrolyte interphase (SEI),...
