The in situ NaCl templating generated NaCl nanoparticles, arising from the reaction between the SbCl and Na MoO precursors, sever as 3 2 4 Porous N-doped carbon nanoﬁbers water-removable pore templates, which generate numerous pores within the CNFs after washing with water. Sb/MoO encapsulation When used as anode materials for lithium ion batteries (LIBs), the porous Sb/MoO @CNFs deliver a high re- Lithium storage properties versible capacity of ∼822 mA h/g at 200 mA/g after 140 cycles, and a
