Integration of Desulfurization and Lithium–Sulfur Batteries Enabled by Amino?Functionalized Porous Carbon Nanofibers

Hydrogen sulfide (H2S) is an industrial exhausted gas that highly toxic to humans and the environment. Combining desulfurization fabrication of cathode materials for lithium–sulfur batteries (LSBs) can solve this issue with a double benefit. Herein, amino-functionalized lotus root-like carbon nanofibers (NH2-PLCNFs) are prepared by amination electrospinning under dielectric barrier discharge plasma. Selective catalytic oxidation H2S elemental sulfur (S) achieved over metal-free NH2-PLCNFs catalyst, obtained composite [email protected]2-PLCNFs further used as in LSBs. enable efficient (removal capacity high 3.46 g g?1 catalyst) strongly covalent stabilization S on modified nanofibers. LSBs equipped deliver specific 705.8 mA h at 1 C after 1000 cycles based spatial confinement electroactive porous matrix. It revealed kind chemical vapor deposition leads more homogeneous distribution superior electrochemical performance sample S/NH2-PLCNF-M traditional molten infusion. This work opens new avenue combination environment protection energy storage.
