Vertical β-MnO₂@δ-MnO₂ Core–Shell Heterostructures with Superior Cycling Stability for All-in-One Flexible Supercapacitors

ACS Applied Nano Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 10, 2025

β-MnO2, as the most stable phase of polycrystalline MnO2, has a narrow tunnel structure that limits ion diffusion and electron transfer, restricting its application in supercapacitors. In this work, we present novel all-in-one MnO2-based material, β-MnO2@δ-MnO2, featuring unique three-dimensional architecture with ultrathin δ-MnO2 nanostructures vertically grown on β-MnO2 network. This innovative design leverages structural support to enhance electrode material's specific surface area effectively mitigate volume changes during adsorption/desorption, key factor for improving cycling stability. As result, β-MnO2@δ-MnO2 composite demonstrates exceptional electrochemical performance, remarkable stability 98% capacitance retention after 10,000 cycles. Additionally, it maintains 74.2% when current density increases from 1.0 20 A g–1, showcasing an outstanding rate capability. When assembled into asymmetric supercapacitor device, electrodes deliver high 287.3 mF cm–2 significant energy 159.3 μWh cm–2. work represents advancement optimization applications, demonstrating practical benefits rational nanostructure design. The not only enhances performance storage devices but also holds potential other offering new opportunities development flexible, high-performance systems.
