“…Derived via AFM measurements, the average Young’s modulus ( E avg ) of PELL60 stands at 10.2 GPa (Figure f), effectively surpassing the threshold (6.2 GPa) required for curtailing lithium dendrite growth. The membrane boasts exceptional stretchability, achieving an elongation of ∼300% (Figure g), which is the top value among the reported self-standing CSEs (Figure h). ,− Upon examination of the stretched PELL60 in the SEM image (Figure S7), no tensile fractures are discernible. The ceramic particles remain intricately intertwined within the polymer matrix, displaying the absence of aggregations or pores.…”

Polymer-in-ceramic composite solid electrolytes (PIC−CSEs) provide important advantages over individual organic or inorganic solid electrolytes. In conventional PIC− CSEs, the ion conduction pathway is primarily confined to the ceramics, while the faster routes associated with the ceramic− polymer interface remain blocked. This challenge is associated with two key factors: (i) the difficulty in establishing extensive and uninterrupted ceramic−polymer interfaces due to ceramic aggregation; (ii) the ceramic−polymer interfaces are unresponsive to conducting ions because of their inherent incompatibility. Here, we propose a strategy by introducing polymer-compatible ionic liquids (PCILs) to mediate between ceramics and the polymer matrix. This mediation involves the polar groups of PCILs interacting with Li + ions on the ceramic surfaces as well as the interactions between the polar components of PCILs and the polymer chains. This strategy addresses the ceramic aggregation issue, resulting in uniform PIC−CSEs. Simultaneously, it activates the ceramic−polymer interfaces by establishing interpenetrating channels that promote the efficient transport of Li + ions across the ceramic phase, the ceramic−polymer interfaces, and the intervening pathways. Consequently, the obtained PIC−CSEs exhibit high ionic conductivity, exceptional flexibility, and robust mechanical strength. A PIC−CSE comprising poly(vinylidene fluoride) (PVDF) and 60 wt % PCIL-coated Li 3 Zr 2 Si 2 PO 12 (LZSP) fillers showcasing an ionic conductivity of 0.83 mS cm −1 , a superior Li + ion transference number of 0.81, and an elongation of ∼300% at 25 °C could be produced on meter-scale. Its lithium metal pouch cells show high energy densities of 424.9 Wh kg −1 (excluding packing films) and puncture safety. This work paves the way for designing PIC−CSEs with commercial viability.

“…7e). 118 By optimizing the ratio of LAGP to PPO, the ion transport channel was adjusted from ''polymer ceramic'' mode to ''ceramic polymer'' mode. When the filling ratio of LAGP in PPO electrolyte reached 75%, the composite solid electrolyte showed good mechanical flexibility, thermal stability, high ionic conductivity, and good lithium dendrite inhibition ability.…”

“…[26] Polyethylene oxide (PEO), as a solvent-free polymer electrolyte, was investigated on the O 2 electrochemistry in a solid-state cell by Hassoun et al [27] The oxidation of peroxides proceeds rapidly to singlet oxygen or more slowly to triplet oxygen, which depends on the lifetime of O 2 * in PEO and on the number of active collisions. Currently, researchers have also tested diverse polymer matrices, including polypropylene oxide, [28] polyvinylidene fluoride (PVDF) [29] and its copolymers with PVDF-HFP, [7] polyvinyl alcohol, [30] polymethyl methacrylate (PMMA), [31] and PAN. [17] Since organic solvent decomposition affects battery performance, Balaish et al first designed a liquid-free LOB based on SPEs in 2015, where the electrolyte was P(EO) 20 LiTf (P(EO) = poly(ethylene oxide) and LiTf = lithium triflate).…”

Li‐oxygen batteries (LOBs) hold great potential for electrochemical energy storage due to their high theoretical energy density. However, the utilization of conventional liquid electrolytes raises safety concerns such as flammability and leakage, which are also problematic in Li‐ion batteries. The development of practical open battery systems employing volatile liquid electrolytes, with the ultimate goal of Li‐air batteries, presents particular challenges. Solid‐state electrolytes (SSEs) have emerged as a promising solution to tackle these issues. In the past two decades, SSEs have garnered significant attention and have been successfully implemented in LOBs. This review aims to highlight recent advancements in SSEs for LOBs, exploring the opportunities and challenges associated with developing SSEs possessing high ionic conductivity, interfacial compatibility, and stability. The objective is to enhance reversibility, promote an increase in stable triple‐phase boundaries, and safeguard the Li anode in open battery systems. Finally, we put forth future directions for the advancement of solid‐state Li‐air batteries.
