A Novel Asymmetric Diffusion Path for Superior Ion Dynamic in High-Voltage Mg-Based Hybrid Batteries.

ABSTRACT: Magnesium-based batteries have garnered significant attention due to their high energy density, excellent intrinsic safety, and low cost. However, the application process has been hindered by the high Mg²⁺ ions diffusion barrier in solid-state structures and solid-liquid interphase. To address this issue, a hybrid battery technology based on Mg anode and Fe-based Prussian Blue Analogue cathode doped with functional transition metal ions and N═O bonds is proposed. Combined multiscale experimental characterizations with theoretical calculations, the subtle lattice distortion can create an asymmetric diffusion path for the active ions, which enables reversible extraction with significantly reduced diffusion barriers achieved by synergistic doping. The optimized cathode exhibits a w
