Multiple core-shelled sulfur composite based on spherical double-layered hollow carbon and PEDOT:PSS as cathode for lithium–sulfur batteries

Novel ceric dioxide nanospheres as sulfur hosts for advanced electrochemical performance of lithium‐sulfur batteries

“…As shown in Fig. 2(a), the as‐prepared CeO 2 nanospheres display typical diffraction peaks at 30°, 36°, 42°, 58°, and 63°, all of which are consistent with previous reported works 22 . Fig.…”

Porous Carbon Nanosphere with Multiple Heteroatom Doping Derived from Silicon Oxycarbonitride as Sulfur Host for Lithium–Sulfur Batteries

“…To prepare S/SiOCN-H cathode material, the active material of sulfur was loaded into SiOCN-H via a simple vacuum infiltration method. [19] Three SiOCN samples of SiOCN-0, SiOCN-1, and SiOCN-2 were prepared, whereas SiOCN-1 and SiOCN-2 were prepared for comparison by adding different amounts of TEOS as pore size controlling agent during the synthesis. Scanning electron microscopy (SEM) images show that all three samples display monodisperse spherical structure with an average size of 100 nm (Figure S1, Supporting Information).…”

Customized Structure Design and Functional Mechanism Analysis of Carbon Spheres for Advanced Lithium–Sulfur Batteries

“…Similar to the alternating barriers provided by multi-shelled CSs, multi-layered coatings are also considered be a more effective strategy to limit LiPSs. Ren et al [277] constructed the spherical double-layered hollow carbon/sulfur spheres coated with a layer of poly(3,4ethylenedioxythiophene):poly(styrenes ulfonate) (DLHC/S@PEDOT:PSS) as sulfur cathode for LSBs. The PEDOT:PSS layer significantly inhibited the dissolution of LiPSs.…”
