“…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].…”

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 (...

This chapter deals with the fundamental properties of polymer nanocomposites (PNC) and their characteristics that play a significant role in deciding their capability for the advanced energy storage device. The various synthesization methods used for the preparation of the polymer electrolytes are described followed by the characterization techniques used for the analysis. The properties of the polymer host, salt, nanofiller, ionic liquid, plasticizer and nanoclay/nanorod/nanowire are described. Various ion transport mechanism with different nanoparticle dispersion in polymer electrolytes are highlighted. The various important results are summarized and a pathway is built to fulfill the dream of the future renewable source of energy that is economical and environmental benign. Chapter motivation is focused on the investigation of the role of polymer host, aspect ratio, surface area, nanoparticle shape and size in terms of boosting the electrolytic/electrochemical properties of PNC. It will certainly help in order to open new doors toward the development of the advanced polymeric materials with overall balancing property for enhancement of the fast solid state ionic conductor which would be revolutionized the energy storage/conversion device technology.

“…However, liquid electrolytes are still applied in LIBs in most cases, and are potentially sources of safety risks. Many studies on polymer electrolytes are currently being conducted in order to substitute liquid electrolytes with non‐volatile and non‐flammable solid electrolytes or gel electrolytes in LIBs …”

A series of poly(ethylene glycol) (PEG)-crosslinked poly(vinylpyridine)s (PVPs)-with PVP serving as the polymer backbone, and PEG side chain of the PVP as the ionic conductor and crosslinker-were developed as novel gel polymer electrolytes. These PEG-crosslinked PVPs combined the advantages of the pendant PEG as ionic conductors on the polymer side chains with the thermomechanically stable PVPs, and showed self-standing film-forming properties without the use of any support. The composition with a pyridine:PEG weight ratio of 45:1 and an ethylene oxide:LiTFSI weight ratio of 10:1, denoted as PVP (45:1)-[10:1], showed a high ionic conductivity of over 1.34 × 10 −5 S/cm at 25 C, and 2.94 × 10 −4 S/cm at 80 C. These properties showed the PEG-crosslinked PVPs to be promising candidate materials as gel polymer electrolytes for lithium-ion batteries.
