“…The polymers were selected due to their high thermal stability and durability as well as for their ability to form dense membranes. [ 3 ] PBI is a fully aromatic heterocyclic polymer with high thermal stability and excellent chemical resistance, [ 69 ] whereas PMDA‐ODAPI is a polyimide also known as “ Kapton” that also shows high thermal stability, mechanical strength, and solvent resistance. The incorporation of [BMIM][TFSI] with a low melting point and good stability increased the CO 2 permeation without decreasing the selectivity and, thus, the composites are promising for CO 2 separation.…”

“…Hyperbranched star polymers with hyperbranched polystyrene as core and polymethylmethacrylate block poly(ethylene glycol) methyl ether methacrylate as arms have been used for the preparation of polymer electrolyte membranes using ILs such as [BMIM][BF 4 ] or [BMIM][PF 6 ] and lithium bis(trifluoromethanesulfonyl) imide ([Li][TFSI]). [ 3 ] Multi‐arm star polymers result interesting for polymer electrolyte design due to its structure that restricts the crystallization of polymer and favors charge carrier's migration. Membranes with excellent flexibility and transparency were obtained with conductivities of 2.5 × 10 −4 and 4.1 × 10 −5 S cm −1 for composites with 40% of [BMIM][BF 4 ] and [BMIM][PF 6 ], respectively.…”

“…[ 2 ] They can include a vast number of organic cations and organic or inorganic anions. The first reported IL, the ethylammonium nitrate, was discovered in 1914 by Walden, [ 3 ] being the first generation of ILs reported in the 1970s–1980s with the development of the alkylimidazolium halogenoaluminate ILs by mixing aluminum halides with imidazolium halides.

Ionic liquids (ILs) have emerged as a novel class of chemical compounds for the development of advanced (multi)functional materials with outstanding potential in applications of several areas due to their unique properties and functionalities. The combination of ILs with polymers, in a composite, allows for developing smart materials, which synergistically combine the features of specific polymers and ILs. Moreover, ILs can be extensively modified by the incorporation of functional groups with specific properties into the cation, anion, or both. Thus, it is possible to tune the IL, the polymer, or both to obtain a broad spectrum of multifunctional composites and address the specific requirements of many applications. This work focusses on advanced materials and strategies concerning ILs and polymers for the development of smart IL/polymer‐based materials for applications including responsive and sensitive sensors, actuators, environment, batteries, fuel cells, and biomedical applications.

“…Furthermore, the electrolyte exhibited good interfacial compatibility in a symmetric Li/SPE/Li cell. Subsequently, the authors studied the electrochemical behaviors of the composite polymer electrolyte with HBPS-(PMMA-b-PPEGMA) 30 (PPEGMA content: 69.56%), ionic liquid, and LiTFSI [84]. In the presence of ionic liquid, the electrolytes exhibited better ionic conductivities but a considerably lower transference number.…”

Solid-state batteries are an emerging option for next-generation traction batteries because they are safe and have a high energy density. Accordingly, in polymer research, one of the main goals is to achieve solid polymer electrolytes (SPEs) that could be facilely fabricated into any preferred size of thin films with high ionic conductivity as well as favorable mechanical properties. In particular, in the past two decades, many polymer materials of various structures have been applied to improve the performance of SPEs. In this review, the influences of polymer architecture on the physical and electrochemical properties of an SPE in lithium solid polymer batteries are systematically summarized. The discussion mainly focuses on four principal categories: linear, comb-like, hyper-branched, and crosslinked polymers, which have been widely reported in recent investigations as capable of optimizing the balance between mechanical resistance, ionic conductivity, and electrochemical stability. This paper presents new insights into the design and exploration of novel high-performance SPEs for lithium solid polymer batteries.

Over the past decade, lithium‐ion batteries (LIBs) have been widely applied in consumer electronics and electric vehicles. Polymer electrolytes (PEs) play an essential role in LIBs and have attracted great interest for the development of next‐generation rechargeable batteries with high energy density. Due to the several practical applications of LIBs and high demands for LIBs performance, many state‐of‐the‐art PEs with different structures and functionalities have been developed to regulate the LIBs performance, especially their rate capability, cycling durability, and lifespan. In this review, the recent advances in high‐performance LIBs prepared using well‐defined PEs are summarized. The ion‐transport mechanisms and preparation techniques of various well‐defined PE classes compared to conventional PEs are also discussed. The aim is to elucidate the structure code for advanced PEs with optimized properties, including ionic conductivity, mechanical properties, processability, accessibility, etc. The existing challenges and future perspectives are also discussed, setting the basis for designing novel PEs for energy conversion applications.
