Since the electrochemical de/intercalation behavior is first detected in 1980, layered oxides have become the most promising cathode material for alkali metal‐ion batteries (Li+/Na+/K+; AMIBs) owing to their facile synthesis and excellent theoretical capacities. However, the inherent drawbacks of unstable structural evolution and sluggish diffusion kinetics deteriorate their electrochemical performance, limiting further large‐scale applications. To solve these issues, the novel and promising strategy of high entropy has been widely applied to layered oxide cathodes for AMIBs in recent years. Through multielement synergy and entropy stabilization effects, high‐entropy layered oxides (HELOs) can achieve adjustable activity and enhanced stability. Herein, the basic concepts, design principles, and synthesis methods of HELO cathodes are introduced systematically. Notably, it explores in detail the improvements of the high‐entropy strategy on the limitations of layered oxides, highlighting the latest advances in high‐entropy layered cathode materials in the field of AMIBs. In addition, it introduces advanced characterization and theoretical calculations for HELOs and proposes potential future research directions and optimization strategies, providing inspiration for researchers to develop advanced HELO cathode materials in the areas of energy storage and conversion.

Rechargeable batteries have been regarded as a truly transformative technology, providing energy storage for portable electronics, power tools, and even electric vehicles. Unfortunately, the practical applications of new battery systems are postponed by some inevitable technical bottlenecks. Sometimes the technical know‐how gained from the current state‐of‐the‐art lithium‐based batteries is untransferable. Therefore, with the continuous development of chemistry, materials and physics, computational materials science has gradually become crucial in supporting the field of rechargeable batteries technically. In this review, brief overviews of computational methods are first presented for the research of battery materials. The study then summarizes the recent advances of computational techniques in assisting experimental analyses, elucidating reaction mechanisms, and exploring new materials. Finally, the challenges and perspectives for future computational research are prospected. This review is anticipated to stimulate design inspiration of novel materials and structures with the assistance of theoretical simulations toward advanced energy storage systems.

Aqueous potassium‐ion batteries (AKIBs) with mild aqueous electrolytes can significantly mitigate the safety and environmental issues raised from traditional nonaqueous batteries, positioning them as promising candidates for grid‐scale applications. Nonetheless, the progression of AKIBs is currently impeded by the insufficient energy density, largely attributed to the limited voltage window of aqueous electrolytes. This review aims to introduce foundational knowledge about aqueous batteries, illustrates recent advancements in AKIBs, and offers valuable perspectives on designing electrode materials and optimizing electrolytes. To provide a systematic overview, the focus is on the following seven key sections: i) development history, ii) electrode materials, iii) electrolyte design, iv) current collectors, v) aqueous interphase chemistry, vi) full cell configurations, and vii) future prospects. Finally, constructive insights and suggestions are provided for the development of AKIBs with higher energy density.
