Single layers of WS2 nanoplates embedded in nitrogen-doped carbon nanofibers as anode materials for lithium-ion batteries

Abstract

Single layers of WS₂ nanoplates are uniformly embedded in nitrogen-doped carbon nanofibers (WS₂@NCNFs) via a facile electrospinning method. Crystallization of the single-layered WS₂ nanoplates and in situ nitrogen doping into the carbon nanofibers were simultaneously accomplished during a two-step heat treatment. The distinctive structure of the WS₂@NCNFs enables outstanding electrochemical performances.
