Lithium-ion batteries (LIBs), as core energy storage devices in the new energy sector, are increasingly employed in electric vehicles, smart grids, and other applications, driving rising demands for higher energy density, longer cycle life, and enhanced safety. Polyimide (PI), with its outstanding thermal stability, mechanical strength, and chemical inertness, offers unique advantages for optimizing the performance of key LIBs components. This review systematically summarizes recent advances in PI-based materials for LIBs separators, binders, and electrode materials, emphasizing structural design, fabrication strategies, performance enhancement, and application outcomes. Furthermore, current challenges in the development of PI-based LIBs are discussed, and future research directions are proposed, providing a reference for the design and engineering of high-performance lithium-ion batteries.
