A review of graphene assembled films as platforms for electrochemical reactions

• Graphene assembled films (GAFs) exhibit ultrahigh conductivity, unique 2D network structure, and exceptional mechanical strength, making them promising electrode materials. • GAFs demonstrate significant advantages in batteries, supercapacitors, and electrochemical sensors due to enhanced ion transport kinetics and interfacial stability. • Challenges such as chemical inertness and mechanical brittleness can be addressed through defect engineering and hybrid structures. • This review provides a systematic understanding of GAFs' structure-property relationships, guiding the development of stable, high-performance electrodes.
