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.

“…Therefore, an anion with a well-delocalized negative charge and low basicity is preferable for high ionic conductivity and plays a dominant role in the reaction. The ion mobility increases with decreasing anion size in the series: LiBF4 > LiClO4 > LiPF6 > LiTf > LiTFSI [99]. But compared to LiBF4, LiClO4 has a strong oxidizing power, making it unsafe to use in LIB.…”

Lithium-ion batteries are still efficient and reliable energy storage systems and are widely used in portable electronics and electric vehicles. This review describes the types of currently existing lithium batteries, systems with anodes, cathodes and electrolytes made of various materials, and methods for their study. Specifically, it begins with a brief introduction to the principles of lithium-ion batteries operation and cell structure, followed by an overview of battery research methods. Particular attention is paid to the use of nanosized particles for the modification of electrodes and electrolytes, as well as the copolymerization of individual polymers of the gel-polymer electrolyte. The review analyzes possible future developments and prospects for post-lithium batteries.

“…Various NMR experiments are widely used to study the cation hydration, water and ion mobility in different spatial scales for uorinated and non-uorinated polymers as well as for non-polymer systems and inorganic ion conductors. [20][21][22][23][24][25] The main idea of the present review is to analyze and discuss the role of liquid and ssNMR spectroscopy and to present current trends of its use for the study of proton conductive systems. The results of NMR spectroscopy used for characterization of hydrogen-bonding and degree of local proton mobility and, consequently, proton conductivity of protic ionic liquids and their nanocomposites, solid proton conductive salts, and uorinated and non-uorinated polymer electrolytes are discussed.…”
