“…Indeed, depending on the contents of polymer and inorganic in the composites, the HSSEs would be transformed from "ceramic-in-polymer" to "polymer-in-ceramic". [32] In-situ polymerization has been introduced to synthesize poly(vinyl carbonate)-Li 10 SnP 2 S 12 (PVCA-LSnPS), providing integrated interphase between electrodes and HSSE with dramatically decreased interfacial impendence.

Conventional liquid electrolytes for lithium batteries usually suffer from irreversible decomposition and safety concerns. Solid state electrolytes (SSEs) have been considered as the key for advanced lithium batteries with improved energy density and safety, whereas challenges remain for polymer and inorganic SSEs. Recently, hybrid solid-state electrolytes (HSSEs) that integrate the merits of different electrolyte systems have been under intensive study. Herein, we summarize the recent progress of HSSEs with different compositions and structures. The design principle of each type of HSSEs are discussed, as well as their ionic conducting mechanism, electrochemical performance and effects of compositional/structural control. Finally, challenges and perspectives are provided for the future development of HSSEs and solid-state lithium batteries.

“…The SEE-10 EDX maps, which are reported in Figure S2a, suggest a seemingly uniform distribution of LLZTO (La), PVDF (F) and LiClO 4 (Cl). [22,63] For example, a critical tensile strength of 0.35 MPa was reported for the PEO-LiClO 4 membrane. This suggests that aggregation preferentially takes place at loadings beyond 10 wt.%, consistent with a previous study.…”

“…[10] While various strategies can be used to make the electrolyte composition less flammable, [11][12][13] in many high-power applications the utilization of organic electrolytes requires the implementation of a number of stringent safety measures. [19,22,23] For example, a porous polymer membrane doped with phytic acid showed a critical tensile strength of 20.71 MPa with an elongation-at-break value of 45.7 %. Many polymer SSEs, such as poly (ethylene oxide) (PEO), have good mechanical properties.…”

Solid-state batteries hold great promise because of their safety and high projected energy density. However, the sizeable interfacial resistance between the electrodes and the electrolyte of such batteries is a significant bottleneck in the development of this technology. In this work, we develop a Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) and polyvinylidene fluoride (PVDF) solid-state composite membrane characterized by high conductivity, tensile strength, and flexibility as well as low impedance if interfacially modified by a minute amount of liquid electrolyte. A solid-state lithium-ion battery using this electrolyte with LiFePO 4 and Li as electrodes delivers excellent rate capability and cycling stability at room temperature. In particular, the battery shows an initial discharge capacity of 155 mAh g À1 and, after 100 cycles at 1C, of 145 mAh g À1 . Even at 4C, the discharge capacity is 96 mAh g À1 . Our study suggests that the interfacially modified LLZTO-PVDF membrane is a promising electrolyte for solid-state lithium-ion batteries.

Polymer electrolytes have aroused wide interest in lithium batteries, but their comprehensive performances (including ionic conductivity, electrochemical window, and mechanical strength) need to be enhanced for high‐energy lithium batteries. A rigid–flexible coupling strategy is proposed to enhance the comprehensive performances of polymer electrolytes. To date, “rigid–flexible coupling” has been widely applied in gel and solid polymer electrolytes. For many kinds of polymer electrolytes, their ionic conductivity, electrochemical window, interfacial stability, and mechanical properties are significantly improved by “rigid–flexible coupling,” breaking their inherent application barriers in high‐energy lithium battery. Herein, recent key progress in rigid–flexible coupling polymer electrolytes is reviewed in terms of their design concepts, chemical‐physical properties, electrochemical performances, and battery properties. This overview also conducts a perspective for rigid–flexible coupling polymer electrolytes. It is hoped that fresh and established researchers can obtain a clear perspective of “rigid–flexible coupling” and this mini review can also throw light on the exploration of high‐energy polymer lithium batteries.
