Vapor selenization produced Bi2Se3 nanoparticles in carbon fiber 3D network as binder-free anode for flexible lithium-ion batteries

Abstract

Bi2Se3 nanoparticles embedded carbon fibers network prepared by electrospinning and selenization in vacuum delivered a large capacity of 443 mA h g-1 after 260 cycles at 100 mA g-1 and a high rate performance as a binder-free flexible anode for LIBs.
