“…Ionic conductivity values for HACC-TFSI-added PEO electrolyte at 30 and 60 • C were 1.77 × 10 −5 S cm −1 and 5.01 × 10 −4 S cm −1 , respectively [200]. In contrast, conductivities of 3.80 × 10 −6 S cm −1 and 1.90 × 10 −4 S cm −1 were recorded at the same temperature by PEO SPE without HACC-TFSI [200]. Besides better conductivity, Li + ion transference number and tensile strength increased by 1.7 and 3.6 times.…”

“…Besides better conductivity, Li + ion transference number and tensile strength increased by 1.7 and 3.6 times. Moreover, the SPE with HACC-TFSI was found to be resistant against elevated temperature (150 • C) by retaining its shape after exposure at high temperature for one hour [200]. On the contrary, the electrolyte without HACC-TFSI has melted under similar conditions.…”

“…A special additive, i.e., hydroxypropyl trimethylammonium bis(trifluoromethane) sulfonamide chitosan salt (HACC-TFSI), was synthesized via ion-exchange route, using hydroxypropyl trimethylammonium chloride chitosan salt and LiTFSI before HACC-TFSI, PEO and LiTFSI were mixed in DMF solvent to form SPE via the solution-casting technique [200]. Ionic conductivity values for HACC-TFSI-added PEO electrolyte at 30 and 60 • C were 1.77 × 10 −5 S cm −1 and 5.01 × 10 −4 S cm −1 , respectively [200].

Electrochemical devices, especially energy storage, have been around for many decades. Liquid electrolytes (LEs), which are known for their volatility and flammability, are mostly used in the fabrication of the devices. Dye-sensitized solar cells (DSSCs) and quantum dot sensitized solar cells (QDSSCs) are also using electrochemical reaction to operate. Following the demand for green and safer energy sources to replace fossil energy, this has raised the research interest in solid-state electrochemical devices. Solid polymer electrolytes (SPEs) are among the candidates to replace the LEs. Hence, understanding the mechanism of ions’ transport in SPEs is crucial to achieve similar, if not better, performance to that of LEs. In this paper, the development of SPE from basic construction to electrolyte optimization, which includes polymer blending and adding various types of additives, such as plasticizers and fillers, is discussed.

“…The use of MOFs promotes the intermolecular interactions in the polymer structure, which inhibits the crystallization of PEO, improving the ionic conductivity, particularly at high temperatures [267]. Ionic liquids are also an effective way to increase the ionic conductivity of an SPE, through the inhibition of the polymer crystallization [268,272]. The immobilization of lithium ionic liquids (LiIL) in a mesoporous silica structure creates a hybrid interface that provides fast Li + transportation kinetics without compromising the mechanical properties.…”

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.

“…[26][27][28] Meanwhile, SPEs based on a poly (ethylene oxide) (PEO) matrix are widely studied for LMBs because of lightweight, good flexibility, and superior compatibility with lithium salts. [29][30][31][32] Unfortunately, the low roomtemperature ionic conductivity impedes their practical application for LMBs. [33] To overcome mentioned above issues, various methods were investigated to enhance the room-temperature ionic conductivity and mechanical strength of SPEs.…”

Dedicated to Professor Rinaldo Poli on the occasion of his 65th birthday.Poly(ethylene oxide) (PEO)-based polymer electrolyte has widely been considered as a promising material for high-performance lithium metal batteries (LMBs) owing to the high safety, low cost, and excellent electrochemical stability. However, PEObased solid polymer electrolyte (SPE) has always been suffered with a poor mechanical strength and low room-temperature ionic conductivity owing to its highly crystalline ethylene oxide (EO) chains. Especially, PEO-based SPE exhibits an unstable framework at elevated temperature (exceed melting temperature), thus leading to the poor electrochemical performances.Here, the electrospun composite polymer membrane (CPM) based on poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) is fabricated by introduction of silica-coated silver nanowires (AgNWs@SiO 2 ). The PEO/LiTFSI is incorporated into the obtained PVDF-HFP/AgNWs@SiO 2 CPM to form the PEO-based SPE. The composite polymer electrolyte membrane (CPEM) exhibits a high mechanical strength and wide electrochemical stability window (> 5.0 V vs. Li + /Li) at 60 °C. The Li/CPEM/ LiFePO 4 cells also show a favorable cycle life at different rates and 92.7 mAh g À 1 (2 C) of discharge specific capacity at 90 °C. Consequently, the PVDF-HFP/AgNWs@SiO 2 CPEM can exhibit an ideal application prospect for LMBs.
