Abstract Graphene fiber supercapacitors (GFSCs) have garnered significant attention due to their exceptional features, including high power density, rapid charge/discharge rates, prolonged cycling durability, and versatile weaving capabilities. Nevertheless, inherent challenges in graphene fibers (GFs), particularly the restricted ion‐accessible specific surface area (SSA) sluggish ion transport kinetics, hinder achievement of optimal capacitance rate performance. Despite existing reviews on GFSCs, a notable gap exists thoroughly exploring kinetics governing energy storage process GFSCs. This review aims address this by analyzing mechanism, fabrication methodologies, property manipulation, wearable applications Through theoretical analysis process, parameters advanced GF methodologies are carefully summarized, which can be used modulate nano/micro‐structures, thereby enhancing kinetics. In particular, enhanced is realized creating more SSA introducing extra‐capacitive components, while accelerated achieved shortening channel length improving accessibility electrolyte ions. Building established structure–property relationship, several critical strategies for constructing structure profiles electrodes summarized. Capitalizing flexibility wearability further underscores potential as foundational elements multifunctional e‐textiles using conventional textile technologies. conclusion, provides insights into current suggests research directions

Due to its excellent performance, reduced graphene oxide aerogel (rGA) has been widely used in recent years. Typically, the mechanical and electrical properties of can be enhanced through doping, compositing, or heat treatment. This work presents a simple, fast, environmentally friendly method for producing high-performance rGA using two reducing agents. During reduction process, ascorbic acid cross-link reduce oxide, while ability ammonium citrate restores conjugated structure sheets. By fixing concentration adjusting amount citrate, we obtain DrGA-2 that possesses both properties. The maximum strain stress are 40.0% 21.5 kPa, respectively. Meanwhile, only 10% compressive is sufficient induce 95% resistance change rate. When assembled into capacitive sensor, capacitance rate ranges from 80% 200% under different conditions, enabling real-time monitoring subtle human movements. demonstrates tremendous potential this material field.
