Abstract Quantum anomalous Hall effect (QAHE) characterized by the presence of multiple non-dissipertive edge conduction channels has garnered substantial research interest owing to its applications in energy-conserving electronic devices. However, observation is constrained extremely low temperatures, which pose challenges for practical implementation.

Abstract Potassium‐containing transition metal layered oxides (K x TmO 2 ), although possessing high energy density and suitable operating voltage, suffer from severe hygroscopic properties due to their two dimensional (2D) structure. Their air sensitivity compromises structural stability during prolonged exposure, therefore increasing the cost. The common sense for designing air‐stable cathode materials is avoid contact with H O molecules. In this study, it surprisingly found that P3‐type K...
