Cover Feature: Recessed Microelectrodes as a Platform to Investigate the Intrinsic Redox Process of Prussian Blue Analogs for Energy Storage Application (Batteries & Supercaps 3/2025)

The Cover Feature shows how recessed microelectrodes were employed as a versatile binder-free platform to investigate the electrochemical performance of Prussian Blue analogues (PBA), a class of promising battery materials, concerning capacity in varying aqueous electrolytes. To corroborate the micro-electrochemical findings, both ex-situ and operando chemical characterizations were conducted, offering complementary insights into the structural and chemical evolution of the PBA material during electrochemical cycling.
