The growing demand for flexible and wearable electronics has accelerated research into energy storage systems that are not only lightweight and efficient but also mechanically resilient. Carbon nanofiber (CNF)/conducting polymer (CP) hybrids have emerged as highly promising materials for such applications due to their complementary electrochemical and mechanical properties. CNFs offer excellent electrical conductivity, high surface area, and robust mechanical strength, while CPs provide pseudocapacitive behavior, flexibility, and tunable electroactivity. The synergy between these two components enhances charge transport, structural integrity, and overall energy storage performance. This review offers an extensive examination of the properties, advantages, and potential of CNF/CP hybrid materials in flexible energy storage devices. The discussion explores various fabrication approaches, emphasizing their influence on the structural design of electrodes and the resulting performance of the device. The application of CNF/CP hybrids in supercapacitors is examined, focusing on parameters like specific capacitance, power density, rate capability, and cycling stability. Additionally, their role in flexible batteries, including lithium-ion and emerging metal-air systems, is analysed in terms of conductivity enhancement and mechanical adaptability. Key challenges such as interfacial compatibility, material degradation, and large-scale manufacturing are addressed. Recent advances aimed at overcoming these limitations are also discussed. The review concludes with future perspectives on material innovation and structural design strategies to enable high-performance, flexible, and wearable energy storage solutions. Overall, CNF/CP hybrids represent a versatile and scalable approach for powering next-generation portable electronics. © 2025 Elsevier B.V.
