Abstract
High-Entropy Doped Metal Oxides@Graphene Fibers In article number 2406483, Haowei Hu, Guan Wu, and co-workers present a high-entropy doped metal oxide/graphene composite fiber for high-performance supercapacitors. The fibrous electrodes have abundant oxygen vacancies, lattice distortions and optimized electronic structure for enhanced electron conduction, ions adsorption/diffusion kinetics, structural stability and Faradaic reversibility. The resultant fiber-shape supercapacitors deliver high areal capacitance, energy density and application potential.
