Today, there is an urgent demand to develop all solid‐state lithium‐ion batteries (LIBs) with a high energy density and a high degree of safety. The core technology in solid‐state batteries is a solid‐state electrolyte, which determines the performance of the battery. Among all the developed solid electrolytes, composite polymer electrolytes (CPEs) have been deemed as one of the most viable candidates because of their comprehensive performance. In this review, the limitations of traditional solid polymer electrolytes and the recent progress of CPEs are introduced. The effect and mechanism of inorganic fillers to the various properties of electrolytes are discussed in detail. Meanwhile, the factors affecting ionic conductivity are intensively reviewed. The recent representative CPEs with synthetic fillers and natural clay‐based fillers are highlighted because of their great potential. Finally, the remaining challenges and promising prospects are outlined to provide strategies to develop novel CPEs for high‐performance LIBs.

Ionogels have established themselves as an intriguing type of composites, owing to their distinctive properties, including superior thermal stability, non‐flammability, tunable electrochemical stability window, and high ionic conductivity. Hybrid materials based on ionic liquids (ionogels) are held together by interfaces arising out of intermolecular interactions, including electrostatic, van der Waals, solvophobic, steric, and hydrogen bonding. The interfaces within the ionic liquid (ILs) and its multifaceted interplay with the encapsulating matrix greatly influence the physicochemical and electronic/ionic interactions within the composite resulting in exceptional characteristics, allowing for the design of ionogels for targeted applications. Though ionogels have shown superior properties comparable to neat ILs, they still exhibit relatively low mechanical strength, limiting their application in several practical technologies. Simultaneous enhancement of mechanical durability while retaining high ionic conductivity is indispensable, which requires understanding interfaces and related influencing parameters. This review provides a synergetic comprehension, focusing on the interactive forces and factors affecting the conductivity, stability, and robustness of ionogels. Correlating with interfaces, several strategies, including the implications of nanofiller incorporation on the electromechanical properties of ionogel, are also elaborated. Finally, a primer is provided on the application of ionogels in sensors and energy harvesting technologies.

Summary In the recent decade, lithium‐ion batteries have flourished in the mobile market to a greater extent. Despite its versatile commercial applications in various fields, it faces critical issues that restrict by safety concerns including leakage, combusting, or even explosions because of the low boiling point of liquid organic electrolytes. In order to mitigate these difficulties, solid electrolytes can be a potential choice. Polymer‐based solid Li‐ion batteries have been attracting researchers for accomplishing high performance. However, poor mechanical strength and low transport of Li+ ions inside the cell remain prominent challenges for its commercialization. To solve these issues and enhance the overall performance, polymer‐based nanocomposite electrolytes developed by incorporating the nanofillers into the polymer matrix have been investigated to a greater extent. This review briefly elaborates on the recent progress of polymer nanocomposite electrolytes for lithium‐ion batteries, factors affecting its performance, and various models used in the interpretation of its performance.
