Polyphenylene sulfide (PPS)-based separators have garnered significant attention as high-performance components for next-generation lithium-ion batteries (LIBs), driven by their exceptional thermal stability (>260 °C), chemical inertness, and mechanical durability. This review comprehensively examines advances in PPS separator design, focusing on two structurally distinct categories: porous engineered via wet-chemical methods (e.g., melt-blown spinning, electrospinning, thermally induced phase separation) nonporous solid-state fabricated through solvent-free dry-film processes. Porous variants, typified submicron pore architectures (<1 μm), enable electrolyte-mediated ion transport with ionic conductivities up to >1 mS·cm-1 at >55% porosity, while counterparts leverage crystalline sulfur-atom alignment trace electrolyte infiltration establish solid-liquid biphasic conduction pathways, achieving transference numbers >0.8 homogenized lithium flux. Dry-processed demonstrate unparalleled dimensional (<2% shrinkage 280 °C) mitigate dendrite propagation uniform electric field distribution, evidenced COMSOL simulations showing stable Li deposition under Cu particle contamination. Despite these advancements, challenges persist reconciling thickness constraints (<25 μm) robustness, scaling manufacturing, reducing costs. Innovations ultra-thin formats (<20 self-healing polymer networks, coupled compatibility extensions sodium/zinc-ion systems, are identified critical pathways advancing separators. By addressing challenges, PPS-based hold transformative potential enabling high-energy-density (>500 Wh·kg-1), intrinsically safe energy storage particularly applications demanding extreme operational reliability such vehicles grid-scale storage.

ABSTRACT Solid polymer electrolytes (SPEs) serve as both separators and electrolytes, enhancing the safety of energy storage devices by eliminating liquid components. In this study, we present SPEs prepared from a blend polyvinyl alcohol (PVA), lithium acetate (LiAc), ionic 1‐ethyl‐3‐methylimidazolium bromide ([EMIm]Br). This combination prevents leakage issues common with addresses low conductivity typical solid electrolytes. The are easy to produce, highly transparent, thermally stable up 271°C, exhibit high conductivity, values 2.21 × 10 −5 S cm −1 when 40% [EMIm]Br is added PVA/10% LiAc membrane. Additionally, composition demonstrates mechanical strength 20.40 MPa an elongation 485.12%. These findings highlight strong potential [EMIm]Br–based for lithium‐ion batteries.
