Much like the more established LIB, SIBs feature positive electrodes made from a diverse array of active materials. Among these, three main categories have emerged as frontrunners: layered oxides, polyanionic compounds and Prussian blue analogues (PBAs). Of these three, PBAs have received significant attention in recent years due to their green elemental makeup and ease of synthesis . Furthermore, PBAs are characterized by an open framework structure with large interstitial spaces that facilitate rapid Na-ion diffusion without significant structural degradation . They have the general formula, Na2-xM`[M(CN)6]1-y•zH2O where a high Na content (x=0), high redox transition metal (M`/M=Mn, Fe, Co, Ni), [M(CN)6] framework with no vacancies (y=0) and no water (z=0) are desired . If these criteria are met, high reversible capacities >200 mAh g -1 rivalling LIB cathode materials are achievable . Such samples have since been successfully synthesized, producing the dehydrated Fe-Fe rhombohedral PBA with formula Na2Fe[Fe(CN)6] known as Prussian White (PW) . This study looks into commercially relevant PW full cells with formula Na1.88Fe[Fe(CN)6] synthesized via a new coprecipitation protocol.
