Abstract

The benchmarking of Fe3+/Fe2+ redox potential at 3.8 V (versus Na) in alluaudite-type Na2Fe2(SO4)(3), along with fast rate kinetics and excellent cycling stability (Nat. Commun., 5, 4358, 2014) has opened up new era of research in Na-ion research. Further insight to the reported material show synthesis is a careful solid-state method involving (a) formation of anhydrous FeSO4 from commercial FeSO4 center dot 7H(2)O, (b) prolonged milling and (c) longer annealing (350 degrees C, 24 h). Journey of such materials from laboratory to industry warrants economic, sustainable and scalable synthesis. Here, we report novel solution assisted-Ionothermal, aqueous spray-drying and pechini synthesis of Na2Fe2(SO4)(3), M = 3d metals] alluaudite cathodes. It will approach (i) salient feature of synthesis, (ii) structure/polymorphism, (iii) magnetic properties and (iv) electrochemical properties of Na2Fe2(SO4)(3) cathode materials.
