“…Thermal stability is an important factor in evaluating the risks SSEs may face during thermal runaway situations. 50 PEO, CF, and ZIF-67@CF/PEO-SN were placed in a vacuum oven at different temperatures (30, 60, 80, 100, and 120 °C) for 1 h. As shown in Figure 4, PEO softened and became transparent at 80 °C. When heated to 100 °C, PEO completely melted and could not form a freestanding film.…”

High-safety and high-energy-density solid-state lithium metal batteries (SSLMBs) attract tremendous interest in both academia and industry. Especially, composite polymer electrolytes (CPEs) can overcome the limitations of singlecomponent solid-state electrolytes. In this work, a strategy of combining a rigid functional skeleton with a soft polymer electrolyte to prepare reinforced CPEs was adopted. The in situ grown zeolitic imidazolate frameworks (ZIFs) with threedimensional cellulose fiber skeleton (ZIF-67@CF) and succinonitrile (SN) plasticizer into poly(ethylene oxide) (PEO) together form ZIF-67@CF/PEO-SN CPEs. The addition of ZIF-67@CF and SN to PEO synergistically enhanced the physical and electrochemical properties of CPEs. Furthermore, the conduction mechanism of lithium-ion (Li + ) in CPEs was studied using density functional theory. It is impressive that the ZIF-67@CF/PEO-SN CPEs at 30 °C exhibit a high ionic conductivity of 1.17 × 10 −4 S cm −1 , a competitive Li + transference number of 0.40, a wide electrochemical window of 5.0 V, a notable tensile strength of 18.7 MPa, and superior lithium plating/ stripping stability (>550 h at 0.1 mA cm 2 ). Such favorable features endowed LiFePO 4 /(ZIF-67@CF/PEO-SN)/Li cell at 30 °C with a high discharging capacity (152.5 mA h g −1 at 0.2 C), a long cycling lifespan (>150 cycles with 99% capacity retention), and superior operating safety. This work provides insights and promotes the application of functionalized CPEs for SSLMBs.

“…Figure 5a−c shows the impedance of SS/electrolyte/SS cells at different temperatures (25,30,40,50, and 60 °C) with PEO, ZIF-67@CF/PEO, and ZIF-67@CF/PEO-SN electrolytes, respectively. The ionic conductivity of cells was calculated from bulk resistance (contact and interfacial resistance) and shown in Table S1.…”

“…Thus, ionic conductivity can be optimized by partial substitution of lattice elements in the crystal structure. [56][57][58] Generally, oxide electrolytes are divided into sodium super ionic conductor (NASICON, LiM 2 (PO 4 ) 3 , M = Ge, Ti, Zr), [59,60] lithium super ionic conductor (LISICON, Li 3+x X x Y 1-x O 4 , X = Si, Ge, Ti, Y = P, As, V, Cr), [61][62][63] Perovskite types, [64,65] Garnet types (A 3 B 2 (XO 4 ) 3 , A = Ca, Mg, Y, La; B = Al, Fe, Ga, Ge, Mn, Ni, V), [66,67] etc. Perovskite-type electrolytes were reported as early as 1953, and their general formula for the Perovskite structure is ABO 3 (the coordinated cations of A and B are 12 and 6, respectively).…”

Solid‐state lithium–sulfur batteries (SSLSBs) have attracted tremendous research interest due to their large theoretical energy density and high safety, which are highly important indicators for the development of next‐generation energy storage devices. Particularly, safety and “shuttle effect” issues originating from volatile and flammable liquid organic electrolytes can be fully mitigated by switching to a solid‐state configuration. However, their road to thecommercial application is still plagued with numerous challenges, most notably the intrinsic electrochemical instability of solid‐state electrolytes (SSEs) materials and their interfacial compatibility with electrodes and electrolytes. In this review, a critical discussion on the key issues and problems of different types of SSEs as well as the corresponding optimization strategies are first highlighted. Then, the state‐of‐the‐art preparation methods and properties of different kinds of SSE materials, and their manufacture, characterization and performance in SSLSBs are summarized in detail. Finally, a scientific outlook for the future development of SSEs and the avenue to commercial application of SSLSBs is also proposed.

“…Due to the expansion of the PS 4 3− lattice and the increased solubility of Li in the LPSCl crystal structure, the ionic transport capacity of the electrolyte was enhanced, and LPSCl-0.02Y exhibited higher ionic conductivity than the original LPSCl in the range of 25–100 ℃. In addition, as shown in Figure 5 b,c, the surface of the LPSCl-0.02Y electrolyte layer is still flat and compact after 100 cycles, offering excellent interfacial compatibility [ 68 ]. Wang et al introduced PVDF polymer into the LPSCl electrolyte ( Figure 5 d).…”

Lithium–sulfur batteries (LSBs) represent a promising next-generation energy storage system, with advantages such as high specific capacity (1675 mAh g−1), abundant resources, low price, and ecological friendliness. During the application of liquid electrolytes, the flammability of organic electrolytes, and the dissolution/shuttle of polysulfide seriously damage the safety and the cycle life of lithium–sulfur batteries. Replacing a liquid electrolyte with a solid one is a good solution, while the higher mechanical strength of solid-state electrolytes (SSEs) has an inhibitory effect on the growth of lithium dendrites. However, the lower ionic conductivity, poor interfacial contact, and relatively narrow electrochemical window of solid-state electrolytes limit the commercialization of solid-state lithium–sulfur batteries (SSLSBs). This review describes the research progress in LSBs and the challenges faced by SSEs, which are classified as polymer electrolytes, inorganic solid electrolytes, and composite electrolytes. The advantages, as well as the disadvantages of various types of electrolytes, the common coping strategies to improve performance, and future development trends, are systematically described.
