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

Bi₂Se₃nanoparticles 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.
