The increasing demand for flexible and portable electronic devices has spurred significant interest in flexible lithium batteries, particularly those utilizing fluoropolymer electrolytes. This review explores the current advancements in the development of fluoropolymer-based solid polymer electrolytes and composite polymer electrolytes, highlighting their unique properties, including high ionic conductivity, electrochemical stability, and mechanical flexibility. Despite their advantages, challenges such as low ionic conductivity due to high crystallinity and dendrite formation during lithium deposition remain critical barriers to commercialization. Recent innovations in polymer chemistry, including the design of nonlinear topological structures and the integration of functional additives, show promise in enhancing the performance of these materials. Strategies for improving interfacial stability and mitigating dendrite growth are also discussed. Future research directions are suggested to optimize the molecular architecture and explore novel composite materials, paving the way for the development of safe and efficient energy storage solutions.
