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

Abstract Traditional slurry‐coated electrodes suffer from limitations such as low electrode energy density.This study proposes a self‐supporting composite construction strategy that simplifies the preparation process. A carbon nanotube (CNT) conductive network is in situ constructed on surface of lithium manganese oxide (LMO) by freeze‐drying, which has both support and ion transport functions. The unique characteristics 1D materials effectively avoid interlayer stacking effect 2D materials, reduce internal resistance, improve charge discharge performance. It worth noting active material content exceeds 90%, less required, thereby reducing costs. achieves an extremely high load up to 45 mg cm −2 specific capacity 125 mAh g −1 , giving full play LMO, so actual reaches 84.5% ideal capacity. Moreover, this process simpler more controllable than traditional slurry coating drying methods, can be produced large scale at cost, with strong practical application potential.
