“…Hence, composite polymer electrolytes (CPEs) with solid-state fillers are widely studied as another method to enhance the Li-ion conductivity of polymer electrolytes. Basically, fillers added in CPEs can be classified into two broad categories: nonionically conductive fillers (e.g., LiAlO 2 , montmorillonite (MMT), vermiculite, Al 2 O 3 , SiO 2 , , etc.) and Li-ionically conductive fillers (Li 7 La 3 Zr 2 O 12 , Li 10 SnP 2 S 12 , Li 6.5 La 3 Zr 1.5 Ta 0.5 O 12 , etc.…”

The lithium−sulfur (Li−S) battery has long been a research hotspot due to its high theoretical specific capacity, low cost, and nontoxicity. However, there are still some challenges impeding the Li−S battery from practical application, such as the shuttle effect of lithium-polysulfides (LiPSs), the growth of lithium dendritic, and the potential leakage risk of liquid electrolytes. Substitution of liquid electrolytes with solid-state electrolytes (SSEs) is an effective strategy to relieve or even solve these problems. This review focuses on the most crucial issues of the solid-state Li−S battery (SSLSB) and exhibits the recent progress in these fields. SSEs applicable in the Li−S battery including inorganic glassy ceramics and ceramics, organic polymers, and inorganic−organic hybrid electrolytes are reviewed. Then, the establishment of Li-ion pathways inside the cathode is discussed in detail. We also probe into the unique polysulfide chemistry of the Li−S battery and expound our opinions. Finally, conclusions and perspectives are outlined for the further development of SSLSBs.

“…For example, the lithium imide, poly(methyl methacrylate), and fumed silica nanoparticles (Li + /PMMA/SiO 2 ) gel electrolyte in the Li–S@RGO-poly( N -methylpyrrole) (PNMPy) cell can enhance the capacity retention and shows high Coulombic efficiency (∼100% CE over 500 cycles) (Figure d). Furthermore, the Li + /PMMA/SiO 2 gel exhibited an ionic conductivity ranging from 2.6 mS cm –1 to 86 mS cm –1 over a wide temperature window of 5–75 °C, and it is also electrochemically stable over 1–3 V. Such gel offers an optimal balance between conductivity, safety, and liquid-like interfacial properties . Besides, the plasticizers could promote the Li + dissociation and form the Li + solvation complexes in single-ion conducting GPEs (SIC-GPEs) (Figure e).…”

Lithium–sulfur (Li–S) batteries have attracted great attention in the past two decades, because of their high theoretical energy density of 2600 Wh kg–1 and the cost-effective sulfur cathode. However, it is still far from commercialization, unlike that of lithium-ion batteries. Although numerous research has been presented on the sulfur cathode, lithium metal anode, separator modification, intercalated layer within the cell configuration, electrolyte design, the problematic issues of the polysulfide shuttling effect cannot be solved effectively. In this Review, we summarize that most challenges in the Li–S battery have involved the electrolyte. The development of Li–S battery electrolytes was discussed from the components of salt, solvent, additives, then the current idea of electrolyte designs including the solid electrolytes was also summarized. This Review aims to give a comprehensive and depth viewpoint on the development, prospect, and challenges of Li–S battery electrolytes.

“…As for the group of ceramic fillers, conventional inert inorganics including mental oxides and fumed oxide particles, such as SiO 2 [159][160][161][162][163][164][165], Al 2 O 3 [166,167] and ZrO 2 [43], have been widely studied for Li-S cells. Take SiO 2 as an example [164], these inert fillers were proved to effectively improve the ionic conductivity for the following reasons: (a) Porous SiO 2 increased liquid electrolytes uptake; (b) Lewis acid-based interactions were formed between polar groups like -OH on the surface of SiO 2 and Li + in liquid electrolytes; and (c) SiO 2 opening up polymer chains made it easier for Li + diffusion (Fig. 9a-d).…”
