Batteries are essential to society for devices such as cell phones, computers, electric vehicles, etc., requiring high voltages and capacities which allow them to have high-energy densities. As we rapidly accelerate towards a more electric world meant to enable an environmentally friendly, sustainable future, the process of producing these batteries presents several environmental, geopolitical, and ethical concerns based on their large dependence on lithium, nickel, and cobalt in the cathode. However, sodium (Na) and iron (Fe) are well poised to replace these metals as they are more abundant, geographically dispersed, and less expensive. Recently, the weberite crystal structure (Na₂M²⁺M’³⁺F₇) has emerged as promising for future cathode materials based on its fast Na⁺ diffusing structure and breadth of compositional variants. Previous studies by the lab on variants of Na₂Fe₂F₇ have shown that Mn²⁺ doping leads to metastability while Mg²⁺ better stabilizes the structure. Motivated by the improved structural stability with a diamagnetic dopant and an interest in better understanding the M³⁺ site, we have prepared a series of Al-doped compositions (Na₂Al_xFe_2-xF₇, x = 0.125, 0.25, 0.5, 1) via a mechanochemical-assisted solid-state synthesis method. The resultant product has been analyzed via lab X-ray diffraction and the data fit via the Rietveld method to determine the phase purity and crystal structure. These results show that we have for the first time successfully prepared Al-doped Fe weberites approaching 90% phase purity. In order to electrochemically test the materials, they were carbon coated in a ball mill to improve their electronic conductivity. Upon carbon coating the lowest Al-content composition for 24 hrs, it was found that the weberite structure decomposed. However, for higher Al concentrations, it was found that the weberite structure could be retained if a shorter carbon coating process was used. Their preliminary electrochemistry is presented and shows respectable reversible capacities of 50 mAh/g. Our preliminary results suggest that we have successfully incorporated Al into the weberite structure. Future structural analysis through ²³Na, ¹⁹F, and ²⁷Al solid-state NMR, ⁵⁷Fe Mössbauer spectroscopy, and Synchrotron X-ray diffraction will enable a fundamental understanding of the M³⁺ site in the weberite structure, thus enabling the development of high-performance Na-ion weberite cathodes.
