| 제목 | Functional interlayers comprising porous nanofibers with core–shell metal oxide@graphitic carbon nanoparticles and well grafted N-doped CNTs for excellent Li–S batteries |
| 초록 | Rationally designed functional interlayers comprising hierarchically porous nanofibers embedded with core–shell Co3O4@graphitic carbon nanoparticles and well grafted N-doped carbon nanotubes (Co3O4@GC/N-CNTNF) for outstanding Li–S batteries. The highly conductive GC layer coated on Co3O4 nanoparticles along with the well-grafted N-doped CNTs provided numerous conductive channels for rapid charge transfer during the redox process. The Co3O4 nanoparticles functioned as active polar sites for effective capturing of polysulfides. Consequently,the assembled Li–S cell employing functional interlayer and a sulfur electrode(70 wt.% and 2.0 mg cm-2 loading) presented an excellent electrochemical performance, namely a high-rate capability and stable cycling performance at C-rates of 0.1, 0.5, and 1.0 C. |
