3D Lithiophilic Freestanding Hosts with SiO_x-Embedded Hierarchical Porous N-Doped Carbon Nanofibers for Dendrite-Free Lithium Metal Batteries.

ABSTRACT: 3D host materials are promising for Li-metal anodes (LMAs) because of their adaptability to volume changes and large areas that prevent current localization, hindering dendritic Li formation. Herein, freestanding porous N-doped carbon nanofibers (PCNFs) with uniformly distributed SiO_x are synthesized by electrospinning and subsequent carbonization. In these composites, tunnel-like, open channels are formed between the CNFs by removing polystyrene (PS) and the hollow N-doped nanocages (HNC) generated from zeolitic imidazolate frameworks-8 (ZIF-8) during carbonization, providing sufficient space for Li deposition. Accompanying these structural advantages, the adequate electron conductivity and lithophilic properties derived from the conductive N-doped CNFs and insulating SiO_x
