ZnS spheres wrapped by an ultrathin wrinkled carbon film as a multifunctional interlayer for long-life Li–S batteries

Abstract

Herein, a graphene-like wrinkled carbon film (WCF) wrapped zinc sulfide (ZnS) spheres hybrid interlayer material was fabricated. Li-S batteries coupled with ZnS@WCF interlayer showed excellent capacity retention and outstanding rate performance.

Integrated Design of Interlayer/Current‐Collector: Heteronanowires Decorated Carbon Microtube Fabric for High‐Loading and Lean‐Electrolyte Lithium–Sulfur Batteries

“…TiO 2 ‐TiN interface shows the lowest activation barrier (0.52 eV) than that of single‐phase TiO 2 (1.96 eV) or single‐phase TiN (1.29 eV), indicating that TiO 2 ‐TiN interface has the synergistic effects for Li 2 S decomposition. [ 35 ] As illustrated in Figure 5i, the synergistic mechanism of CCC@TiO 2 ‐TiN heteronanowires is reflected. In general, the LiPS is adsorbed first by TiO 2 surface, and then diffuse smoothly though the TiO 2 ‐TiN interface to the TiN surface, which synergistically proves in situ capture‐catalysis function of CCC@TiO 2 ‐TiN for sulfur species.…”

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

“…In addition to the introduction of metal sulfides into the CS host, of interest, is that some sulfide additives were further employed as LiPSs trapper together with CSs for the interlayer in LSBs. The strong sulfur immobilization of CoS 2 , [254] ZnS, [205] impregnated CSs has been proven. Compared with pristine separator, metal sulfides-modified separator can better limit LiPSs via interaction on the polarized surface.…”

“…In terms of separator modification, Recently, Yang et al [205] fabricated a functional interlayer by wrapping zinc sulfide nanospheres with a graphene-like ultrathin wrinkled carbon film (ZnS@WCF). When applied in LSBs, as shown in Figure 7g, the ZnS@WCF serves as a flexible cross-linked physical barrier to prevent LiPSs shuttle.…”

Regulating Li+ migration and Li2S deposition by metal-organic framework-derived Co4S3-embedded carbon nanoarrays for durable lithium-sulfur batteries

“…The Li 2 S 6 solution was prepared by a method as reported in the previous study [22]. Afterwards, 50 mg of CC, Co/C@CC or Co 4 S 3 /C@CC was, respectively, added into 3 mL of 2.25 mmol L −1 Li 2 S 6 solutions and incubated for a while in an Ar-filled glove box.…”
