In this section, the potential of these functional polymer nanoparticles in composite solid electrolytes for lithium batteries is discussed. Two types of composites were investigated. In the first case, the particles were mixed with a polymer electrolyte based on poly(ethylene oxide), forming an all-polymer nanocomposite. In the second case, the nanoparticles were combined with a solvent or liquid electrolyte to prepare the nanocomposite gel electrolytes.

1 Introduction Epoxy resins are among the most widely used thermosets in high-performance materials, thanks to their outstanding mechanical, thermal, and chemical properties.[1, 2] Their crosslinked networks, often formed through reactions between epoxides and amines, are well understood and broadly applied in sectors ranging from aerospace to electronics.[3] Over time, however, the demands on epoxy systems have evolved, with increasing interest in endowing them with additional...
