Abstract Because of its low cost and abundant sources, hydrogen serves as a clean energy alternative capable successfully substituting fossil fuels. A highly efficient method for generating currently is by the electrolysis water. The oxygen‐extraction reaction (OER), component water electrolysis, requires complex chemical pathway that involves multiproton multielectron interactions. To enhance efficiency in OER process, catalysts are crucial; thus, search high‐performance, cost‐effective underway. This experimental study involved enhancement five‐membered high‐entropy oxide (FeCoNiMnCu) 3 O 3.2 incorporating sixth group element (Zn, Al). organization, morphology, properties were analyzed following preparation utilizing mechanical ball milling process. series rock salt‐type hexagonal high entropy oxides with differing durations synthesized to investigate influence production on surface shape catalytic oxides. results indicated single‐phase salt structure (FeCoNiMnCuAl) 3.5 , oxide, exhibited significantly altered diffraction peaks, hence improving performance. Optimization technique revealed 72‐h duration resulted an overpotential merely 293 mV electrochemically active area approximately double other durations.

Abstract Electrochemical energy storage (EES) demonstrates significant potential for large‐scale applications in renewable storage. Among these systems, vanadium redox flow batteries (VRFB) have garnered considerable attention due to their promising prospects widespread utilization. The performance and economic viability of VRFB largely depend on critical components, including membranes, electrodes, electrolytes. However, as the fundamental materials ion conduction, often struggle effectively balance proton transfer while preventing crossover, enhancing long‐term stability, reducing manufacturing costs. Additionally, inherent structural limitations surface property defects electrode significantly impact improvement V 2+ /V 3+ electrochemical reaction kinetics enhancement power density. Furthermore, composition concentration electrolyte play a crucial role determining cost VRFB, well its density cycling performance. This review analyzes summarizes each component, reviews evaluates latest research advancements material modification, optimization, processes components over past 5 years. Moreover, comprehensive assessment environmental sustainability, feasibility, is presented, aiming provide strategic guidance commercialization VRFB.
