“…Accordingly, the σ orders of the UV-cured electrolytes, CPEs, were ca. 3.4 × 10 –5 , 1.5 × 10 –4 , 3.5 × 10 –4 , and 5.5 × 10 –5 S·cm –1 for CPE-1, CPE-2, CPE-3, and CPE-4, respectively, at 30 °C (Figure a), and these results are comparable to or greater than other reported UV-cured cross-linked polymer electrolytes. − While with the increase of temperature all of the CPEs exhibited higher σ, CPE-1, CPE-2, CPE-3, and CPE-4 showed enhanced σ values of ca. 2.60 × 10 –3 , 4.40 × 10 –3 , 8.50 × 10 –3 , and 1.83 × 10 –3 S·cm –1 , respectively, at 80 °C, which is probably due to the change of CPEs polymer phase with the increase of temperature …”

UV-cured cross-linked polymer electrolytes are promising electrolytes for safe Li-ion batteries (LIBs) application due to their excellent conduction ability, low glass-transition temperature (T g ), and high discharge capacity. Herein, we have prepared novel fluorosulfonylimide methacrylic-based cross-linked polymer electrolyte membranes for LIBs via UV-curing process, which is a well-known, easy, low-cost, fast, and reliable technique. The synthesized UV-reactive novel methacrylate monomer with directly attached fluorosulfonylimide functional group methacryloylcarbamoyl sulfamoyl fluoride (MACSF) was used as a precursor for UV curing along with poly(ethylene glycol) dimethacrylate (PEGDMA) and lithium bis(fluorosulfonyl)imide (LiFSI). The results demonstrated that the cross-linked membrane with an optimized amount (30 wt %) of MACSF monomer (noted as CPE-3) showed the best performance. The nonflammable fluorosulfonyl group (a hydrophilic group of MACSF monomer) in the polymer matrix formed a wide channel, as a result of which Li ion can migrate easily via forming an ionic linkage. The CPE-3 electrolyte exhibited a low T g (−79 °C), excellent phase separation, high conductivity (σ) (ca. 3.5 × 10 −4 and 8.50 × 10 −3 S•cm −1 at 30 and 80 °C, respectively), and high flame retardancy. The battery performance of half-cell (LiFePO 4 /CPE-3/Li) and full cell (LiFePO 4 /CPE-3/graphite) with CPE-3 electrolyte were attractive: discharge capacities (155 and 152 mAh/g) with the capacity retentions of 96.17 and 95.17% after 500 cycles at 0.1 C rate for half-cell and full-cell LIBs, respectively.

“…The organic matrix or organic-inorganic matrix gel electrolyte can be prepared by physical or chemical methods. The physical one, also known as a solvent-assisted method, involves the dissolution of polymer matrices such as poly (vinylidene fluoride-hexafluoropropylene(PVDF-co-HFP), [69][70][71][72][73][74][75] poly(vinylidene fluoride-hydroxy ethyl acrylate) (PVDF-co-HEA), poly(propylene carbonate) (PPC), [76] block copolymers [77,78] in organic solvents (e. g., acetone, dimethyl formamide), and then mix with inorganic filler and other additives (e. g., SiO 2 , [79][80][81][82][83][84][85] TiO 2 nanoparticles). Finally, the organic solvent is evaporated, and the polymer membrane is swollen with electrolytes containing lithium and IL.…”

Incidents in the use of lithium-ion batteries are usually caused by the malfunction of flammable organic liquid electrolytes with poor thermal stability. Therefore, the development of noncombustible electrolytes is regarded as one of the most effective means to prevent the safety hazards of lithium-ion batteries. Ionic liquids have attracted much interest recently, mainly due to their high ionic conductivity, low volatility, and incombustibility. The application of ionic liquids to the preparation of quasi-solid-state gel electrolytes combines the advantages of ionic liquids and avoids the risks of organic liquid electrolytes. Therefore, the solid-state ionogels have been considered as a promising alternative electrolyte system, especially for the much-desired energy storage devices with higher energy density and flexibility. This review focuses on the recent progress of ionogel electrolytes for lithium-ion batteries. The preparation strategies for ionogel electrolytes based on different frameworks, namely inorganic matrix, organic matrix, and organicinorganic hybrid matrix, are discussed. Subsequently, efforts to improve the properties of the ionogel electrolytes, including the ionic conductivity, mechanical properties, and lithium-ion transfer number, are summarized. Besides, the applications of ionogel electrolytes in high-voltage lithiumion batteries and lithium metal batteries as well as the batteries under extreme environments are outlined. Finally, the perspectives on studying and improving the performances of ionogel electrolytes for advanced lithium-ion batteries are provided.

For the past decade, lithium ion batteries have dominated the high‐performance and mobile markets. Despite their domination in many sectors, the development of contemporary commercial lithium ion batteries is hampered by safety concerns such as leakage, burning and even explosions caused by organic liquid electrolytes with low boiling points. Polymer electrolytes are a promising option to solve or mitigate these issues. Polymer electrolytes have the advantages of low flammability, good flexibility, excellent thermal stability and high safety. Among others, polyurethane (PU) has attracted attention as a promising polymer electrolyte candidate for the future. The soft and hard segments of the polymeric chain given by polyols and isocyanates, respectively, give PU its characteristic multiphase structure. The PU's soft segment can operate as a polymeric solvent to solvate the cations, while the hard segment can be functionalized to retain a wider range of electrochemical stability, allowing the construction of polymer electrolytes in electrochemical devices. Numerous researchers have concentrated on developing high‐performance PU‐based polymer lithium ion batteries. Nonetheless, low lithium ion conductivity characteristics remain the most significant obstacles to its commercialization. In order to tackle the issues and improve the overall performance, both physical and chemical modifications are widely investigated to form a PU‐based polymer electrolyte. In the light of this work, this review discusses PU as a polymer host and the approaches to increase its ionic conductivity, including polymer blending, copolymerization, crosslinking, filler addition, plasticization, salt dopant addition as well as the integration of PUs into polymeric ionic liquids. In this review, previous work regarding PU‐based polymer electrolytes from 1988 to 2021 is discussed and summarized. © 2022 Society of Industrial Chemistry.
