Solid polymer electrolytes (SPEs) offer a safer and more stable alternative to conventional liquid electrolytes in lithium-ion batteries, addressing key concerns such as leakage and flammability. However, their practical implementation is limited by mechanical vulnerabilities—particularly crack formation—which can lead to short circuits and compromise safety. To mitigate these risks, there is an urgent need for SPEs that are not only flexible but also capable of autonomous self-healing and fire resistance, thereby preventing thermal runaway and enhancing overall battery reliability. While self-healing functionalities have shown promise, their integration often comes at the cost of diminished electrochemical performance, particularly ionic conductivity. This research aims to overcome that trade-off by designing and synthesizing novel SPEs with rapid self-healing and flame-retardant properties, utilizing supramolecular interactions and polymeric ionic liquids. To further improve mechanical robustness and ensure long-term operational reliability, the project proposes a dual-reinforcement strategy: chemically cross-linked polymer networks will provide dimensional stability, while electrospun nanofiber mats—based on polyacrylonitrile (PAN) and its blends with poly(ethylene oxide) (PEO)—will serve as physical scaffolds to enhance both mechanical strength and ionic transport via polar group interactions. The research will encompass synthesis, structural and morphological characterization, and comprehensive mechanical, thermal, and electrochemical evaluation of the developed SPEs. The anticipated outcomes include the creation of flexible, self-healing, and flame-retardant electrolytes with superior safety and performance, suitable for next-generation lithium-ion batteries. The success of this project could represent a significant advancement in the field of solid-state batteries and contribute to the broader transition toward safer, more reliable energy storage systems.
