ABSTRACT Supercapacitors are promising energy storage solutions known for their high‐power density, fast charge–discharge rates, and long cycle life. Recently, Ti 3 C 2 T x MXene, a member of the 2D MXene family, has emerged as potential electrode material supercapacitors. However, its limited interlayer spacing hinders broader applications. In this study, we introduce novel δ‐MnO @MXene heterostructure with expanded spacing, synthesized using hydrothermal approach. This design enhances charge transfer efficiency improves contact between components, significantly boosting supercapacitor performance. The unique nanoflower‐like structure combined substantially capacitance retention ion diffusion, surpassing performance each individual material. sponge‐like architecture increases accessible sites widens gaps in facilitating better migration. As result, exhibits 54 times greater than alone (2.0 F g⁻¹), an impressive rate capability 67.3% (after 20‐fold increase current density), exceptional cycling stability, maintaining 93% capacity after 10,000 cycles. electrochemical performance, making it candidate advanced
