Improved Lithium Sulfur Batteries
NiCo2S4‐x nanoplates with sulfur vacancy are grown on the flexible carbon fiber paper as the interlayer of the Li‐S battery. The 2D nanoplate morphology of NiCo2S4‐x increases the effective adsorption sites for lithium polysulfides (LiPSs), and the Lewis acidic sulfur vacancy could regulate the precipitation and conversion behaviors of LiPSs, resulting in improved...
The low conductivity of sulfur and the shuttle effect of lithium polysulfides (LiPSs) are the two intrinsic obstacles that limit the application of lithium–sulfur batteries (LSBs). Herein, a sulfur vacancy introduced NiCo2S4 nanosheet array grown on carbon nanofiber (CNF) membrane (NiCo2S4‐x/CNF) is proposed to serve as a self‐supporting and binder‐free interlayer in LSBs. The conductive CNF skeleton...
