The emergence of lithium metal batteries (LMBs) as a promising technology in energy storage devices is attributed to their high energy density. However, the inherent flammability and leakage of the internal liquid organic electrolyte pose serious safety risks when exposed to heat. In response to this challenge, gel polymer electrolytes (GPEs) have been developed to mitigate leakage and enhance nonflammability by incorporating flame-retardant groups, thereby improving the safety of LMBs. This review commences with a brief analysis of the thermal runaway mechanism specific to LMBs, emphasizing its distinctions from that of lithium-ion batteries. Following this, the various methods employed to assess the safety of LMBs are discussed, including flammability, thermal stability, and abuse assessment. The following section categorizes recent research on safe GPEs according to different flame retardancy levels providing a concise overview of each category. Finally, the review explores current advancements in developing safety-oriented GPEs and considers potential future research directions.

As a new generation of green media and functional materials, ionic liquids (ILs) have been extensively investigated in scientific and industrial communities, which have found numerous ap-plications in polymeric materials. On the one hand, much of the research has determined that ILs can be applied to modify polymers which use nanofillers such as carbon black, silica, graphene oxide, multi-walled carbon nanotubes, etc., toward the fabrication of high-performance polymer composites. On the other hand, ILs were extensively reported to be utilized to fabricate polymeric materials with improved thermal stability, thermal and electrical conductivity, etc. Despite substantial progress in these areas, summary and discussion of state-of-the-art functionalities and underlying mechanisms of ILs are still inadequate. In this review, a comprehensive introduction of various fillers modified by ILs precedes a systematic summary of the multifunctional applications of ILs in polymeric materials, emphasizing the effect on vulcanization, thermal stability, electrical and thermal conductivity, selective permeability, electromagnetic shielding, piezoresistive sensitivity and electrochemical activity. Overall, this review in this area is intended to provide a fundamental understanding of ILs within a polymer context based on advantages and disadvantages, to help researchers expand ideas on the promising applications of ILs in polymer fabrication with enormous potential.

“…Very recently, elastic electrolytes such as poly-butyl acrylate/succinonitrile, [23] SiO 2 /poly(propylene oxide), [24] and rubber-derived electrolytes [25][26][27] have been synthesized via polymerization-induced phase separation, covalent-dynamic hydrogen bonding dual-crosslinking, and vulcanization methods, respectively. Owing to their good resilience and high durability, these elastic electrolytes can form a conformal interface with electrodes resulting in improved cycling performance in solid-state LMBs.…”

Although high ionic conductivities have been achieved in most solid‐state electrolytes used in lithium metal batteries (LMBs), rapid and stable lithium‐ion transport between solid‐state electrolytes and lithium anodes remains a great challenge due to the high interfacial impedances and infinite volume changes of metallic lithium. In this work, a chemical vapor‐phase fluorination approach is developed to establish a lithiophilic surface on rubber‐derived electrolytes, which results in the formation of a resilient, ultrathin, and mechanically integral LiF‐rich layer after electrochemical cycling. The resulting ultraconformal layer chemically connects the electrolyte and lithium anode and maintains dynamic contact during operation, thus facilitating rapid and stable lithium‐ion transport across interfaces, as well as promoting uniform lithium deposition and inhibiting side reactions between electrolyte components and metallic lithium. LMBs containing the novel electrolyte have an ultralong cycling life of 2500 h and deliver a high critical current density of 1.1 mA cm−2 in lithium symmetric cells as well as showing good stability over 300 cycles in a full cell.
