Cation-Water Dynamics in Prussian Blue Analogues Cathodes.

ABSTRACT: Prussian blue analogues (PBA) cathodes are emerging as promising electrode materials for post-Li batteries due to their open framework, high theoretical capacity, and fast ion diffusion channels. Their large interstitial sites facilitate the reversible intercalation of both small and bulky cations, enabling efficient charge storage. These interstitial spaces, however, can also accommodate water molecules, which significantly influence the charging mechanism and, consequently, the electrochemical performance of PBA. Since water is nonelectroactive at the working potential of PBA cathodes, monitoring the dynamics of H₂O during charging is a challenging task. As a result, a comprehensive understanding of its contribution to the electrochemical behavior of PBA is still lacking. To a
