Generation of activated carbon nanofibers from electrospun polyacrylonitrile-zinc chloride composites for use as anodes in lithium-ion batteries

摘要

Activated carbon nanofibers (CNFs) with large surface areas and small pores were prepared by electros_pinning and subsequent thermal and chemical treatments. These activated CNFs were examined as anodes for lithium-ion batteries (LIBs) without adding any non-active material. Their electrochemical behaviors show improved lithium-ion storage capability and better cyclic stability compared with unac- tivated counterparts. The results demonstrate that the unique structures and properties of these materi_als make them promising candidates as anodes in LIBs.
