“…This observation was evidenced by various results reported earlier [41,57,[139][140][141]. The PEO-built solid electrolytes displayed an appropriate conductivity value (10 −4 S cm −1 ) for commercial LIB usage only after their crystalline temperature (T m ); in this case, the amorphous domains are dominant, which permits lithium ions to perceive a greater number of lithium charge carriers [41,120,[142][143][144]. Thus, many attempts have been made, aiming to reduce the crystallinity, as well as to improve the robustness and conductivity in solid polymer electrolytes, which include blended matrices, branched hosts, bulky anionic lithium salts, and the incorporation of additives, such as fillers and plasticizers [145][146][147][148].…”

“…Apart from their chemical and electrochemical stabilities, some ILs are played as a wetness barrier, which is due to their trifling vapor pressure. Hence, the scientific community has been focused on decorating the concept of gel polymer electrolytes in electrolyte chemistry to incorporate IL moieties into polymer host structures, including poly(vinylidene fluoride) (PVdF) [120], poly (ethylene oxide) (PEO) [121] , poly(vinylidene fluoride) hexafluoropropylene (PVdF-co-HFP) [51], poly(acrylonitrile) (PAN) [122], poly (methyl methacrylate) (PMMA) [123,124], polystyrene-block-poly methyl methacrylate-block-polystyrene (PS-b-PMMA-b-PS) [125], etc.…”

“…A new class of IL, PYR 14 TFSI in a PEO matrix, subsequently enhances the chemical and electrochemical properties of SPEs [55], which are capable of providing the theoretical capacity (170 mA h g −1 ) at 30 • C through excellent cyclability. In a similar fashion, ILs, like PYR 14 TFSI, Im 13 TFSI, DEME-TFSI and PP 13 -TFSI, Im 13 TFSI, Im 23 PF 6 , etc., have been extensively studied and characterized for SPEs in LIB applications using PEO as the host polymer matrix [20,30,79,116,120,[149][150][151][152]. Apart from PEOs, SPEs containing other polymer hosts have also been extensively studied [98,139,153].…”

Since the ability of ionic liquid (IL) was demonstrated to act as a solvent or an electrolyte, IL-based electrolytes have been widely used as a potential candidate for renewable energy storage devices, like lithium ion batteries (LIBs) and supercapacitors (SCs). In this review, we aimed to present the state-of-the-art of IL-based electrolytes electrochemical, cycling, and physicochemical properties, which are crucial for LIBs and SCs. ILs can also be regarded as designer solvents to replace the more flammable organic carbonates and improve the green credentials and performance of energy storage devices, especially LIBs and SCs. This review affords an outline of the progress of ILs in energy-related applications and provides essential ideas on the emerging challenges and openings that may motivate the scientific communities to move towards IL-based energy devices. Finally, the challenges in design of the new type of ILs structures for energy and environmental applications are also highlighted.Polymers 2020, 12, 918 2 of 37 and structural stability of the ionic species are extremely crucial and responsible for the efficient outputs in energy storage devices. In the light of this fact, high current (i.e., automotive applications) operating devices are required to have storage devices that have higher power density and faster ion transport properties. Previous studies have suggested that one of the most favorable approaches to simultaneously progress the safety, along with energy and power densities, is the incorporation of ILs into the electrolyte system [11].In past decades, room temperature ionic liquids (RTILs) have been acknowledged with noteworthy attention due to their excellent miscellaneous properties, such as thermal and chemical stability, tunable structure over the wide range of operating temperature, a broad electrochemical stability window, high ionic conductivity in the range of 10 −3 -10 −2 S cm −1 at room temperature, and non-flammability as a potential candidate for EES devices, such as LIBs [12], electric double-layer SCs [13][14][15], proton exchange membrane fuel cells, and solar cells [16][17][18][19]. Using ILs as an alternative to organic electrolytes has the advantage of improving the ions' mobility, as well as eliminating the hazards associated within the organic electrolytes. Additionally, ILs often have comparable zero or negligible vapor pressure at normal temperatures due to their high thermal stability. Because of the above statements, ILs are widely used as solvents or electrolytes for energy storage applications in recent times [7,18,[20][21][22][23][24][25][26][27].Typically, ILs are organic salts, also defined as molten salts, which have a lower melting point (<100 • C) with a wide degree of variation. Moreover, they are comprised of organic cations, such as an pyridinium (PY) [28], imidazolium (Im) [29][30][31][32], pyrrolidinium (PYR) [33][34][35][36], ammonium [37], and sulfonium [38], derivatives joined inorganic or organic anions, such as BF 4 − [39,40], PF 6 − [30], triflate (...

“…A slight decay in capacity occurs with increase of number of cycles and it delivers a discharge capacity of 120 mAhg −1 after 100 th cycle. The slight decrease in capacity during the first few cycles may be due to formation of passive layers over the lithium electrode surface during the cycling 55 – 58 . Moreover, no obvious changes are observed in charge capacity after few cycles which infers from the capacity retention curve as shown in Fig.…”

A new generation of boronic ionic liquid namely 1-ethyl-3-methylimidazolium difluoro(oxalate)borate (EMImDFOB) was synthesized by metathesis reaction between 1-ethyl-3-methylimiazolium bromide and lithium difluoro(oxalate)borate (LiDFOB). Ternary gel polymer electrolyte membranes were prepared using electrolyte mixture EMImDFOB/LiDFOB with poly vinylidenefluoride-co-hexafluoropropylene (PVdF-co-HFP) as a host matrix by facile solvent-casting method and plausibly demonstrated its feasibility to use in lithium ion batteries. Amongst ternary gel electrolyte membrane, DFOB-GPE3, which contained 80 wt% of EMImDFOB/LiDFOB and 20 wt% PVdF-co-HFP, showed excellent electrochemical and cycling behaviors. The highest ionic conductivity was found to be 10−3 Scm−1 at 378 K. Charge-discharge profile of Li/DFOB-GPE3/LiCoO2 coin cell displayed a maximum discharge capacity of 148.4 mAhg−1 at C/10 rate with impressive capacity retention capability and columbic efficiency at 298 K.

“…Quite a lot of anions based electrolyte mixtures such as TFSI À , CF 3 SO 3 À , BF 4 À , nonaate are successfully used as gel polymer electrolytes in lithium-ion battery. [23][24][25][26][27][28] Among them, rhodanide anion (familiarly known as thiocyanate SCN À ) is believed to be most promising anion for electrolyte preparation because it has a strong electron withdrawing group, possesses a lower LUMO (Low Unoccupied Molecular Orbital) and a higher electrochemical stability for wide electrochemical window towards batteries with high energy. 29,30 In the present study, we report a new class of ternary gel polymer electrolyte (TILGPEs) membranes prepared by encompassing rhodanide anion based lithium salt and ionic liquid [1-ethyl-3methylimidazolium rhodanide (EMImSCN)] into a PVdF-co-HFP matrix.…”
