In this study, we showcase the production of Fe2O3 nanosheet anodes for Na-ion batteries using a straightforward yet highly feasible industrial method. These anodes exhibit remarkable reliability in the pseudocapacitive realm. Their exceptional charge transport properties and effective buffering against volume fluctuations stem from a distinctive blend of two-dimensional morphology and precisely tuned crystal perturbations.
Nanosheets of iron oxide were fabricated through a two-stage heating procedure. The crystal structure features of the iron oxide nanosheets were examined through X-ray diffraction (XRD) analysis. XRD patterns were acquired utilizing a Rigaku Rint-2000 diffractometer fitted with a Cu Kα source (λ = 1.54 Ả). Raman spectroscopy was employed to investigate the nanoplates, utilizing a Thermo Scientific DXR3 Raman microscope for micro-scale analysis. Additional examination of the morphological properties and elemental distribution of the nanosheets was performed through transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) mapping.
The presented approach for the creation of high-performance, stable, and cost-effective transition metal oxide electrodes through an industrially feasible method can serve as a blueprint for designing and developing other sustainable, high-performance electrode materials.
