Abstract Sodium‐ion batteries (SIBs) gain attention as a promising, cost‐effective, and resource‐abundant alternative, especially for large‐scale energy storage. Cathode materials play pivotal role in improving the electrochemical performance of SIBs, with high‐voltage cathodes providing enhanced density rate capacity, making SIBs suitable high‐power applications. Common cathode materials, such layered transition metal oxides, polyanionic compounds, Prussian blue analogs, each offer unique benefits. However, these face challenges under conditions, phase transitions, cation migration, oxygen loss, electrolyte degradation. This review discusses strategies to address challenges, including elemental doping, surface coatings, modified synthesis methods, interfacial adjustments, all aimed at enhancing stability materials. Here also explores how full‐cell design optimizations can further improve power density. By analyzing material degradation failure modes, this offers insights into development stable, high‐performance better safety broader application potential storage technologies.

Metal single atoms are widely used to optimize the microstructure of carbon materials improve their ion storage capacity and rate performance, but impact on another key parameter, Coulombic efficiency (CE), is not sufficiently addressed confirmed. Herein, a universal phenomenon reported that carbon-loaded asymmetric sulfur-modified metal-N4 moiety (MN4-S, M = Zn, Fe, Cu, Ni) possesses higher CE than symmetric MN4 moiety, this applicable various matrices, ions (Li+, Na+, K+), charge discharge rates, electrolyte formulations. The MN4-S exhibits larger CEs (0.03-0.46% average CEs, 4.2-28.4% initial CEs) smaller variance compared implying better reversible stability. mechanism driving revealed by ZnN4-S sodium process. coordination promotes rapid diffusion kinetics changing density. Meanwhile, can reduce adsorption energy regulate surface chemical reactivity material increase reversibility storage, thereby achieving
