However, the low electronic conductivity and frail layered structure give rise to its poor cycling stability and low rate performance. Herein, by taking advantages of the porous structure and the high N content of metal-organic frameworks (MOFs) derivatives, a facile and scalable method combining electrospinning and following a hydrothermal process was developed to fabricate MoS2-based composite fibers, in which ultrathin MoS2 nanoplates were vertically assembled on the polyacrylonitrile-MOF-derived N-doped porous carbon nanofibers (PCNF). As expected, benefiting from the hierarchical structure of PCNF and the synergies between MoS2 and PCNF, the obtained PCNF@MoS2 exhibited high capacity and cycling performance in a lithium battery.Graphical abstract
