  abstract     = {Prussian blue (PB) and Prussian blue analogues (PBAs) are a class of porous materials composed of transition metal cations, cyanide ligands, and alkali metal cations. Their ability to intercalate and deintercalate ions within their framework pores, coupled with the adaptability of their crystal structure to electrochemical changes, underpins their success in battery applications. PBAs with Fe or Co as the active site exhibit high redox potentials (vs SHE) and have been extensively explored as cathode materials, with well-documented chemistry, crystal structures, and electrochemical properties. In contrast, PBAs with Cr or Mn as the active site display lower redox potentials and remain significantly underexplored as anode materials. This gap has led to fewer reported compounds and a less comprehensive understanding of their structural and electrochemical behavior, leaving the field relatively opaque. In this perspective, we comprehensively analyze the challenges involved in producing and employing PBAs with low redox potentials as active battery materials. Conversely, we propose numerous horizons and ask fundamental questions that should pave the way for future research to advance the field.},

  abstract     = {The determination of the intrinsic properties of solid active material candidates is essential for their performance optimization. However, macroscopic electrodes and related analytical techniques show challenges concerning the number of additional influencing parameters. We explore recessed microelectrodes (rME) as a platform that allows for a binder-free investigation of Prussian Blue analogues (PBA), a family of promising battery materials. The enhanced diffusion using microelectrochemical tools is indispensable to assess the intrinsic material performance, overcoming the limitation of cation diffusion from the electrolyte to the solid interface during (dis)charging cycles and allowing the investigation of limiting steps in the coupled ion-electron transfer process. The intrinsic electrochemical performance of PBAs was studied in a three-electrode configuration by means of cyclic voltammetry and galvanostatic (dis)charging in aqueous Na+-containing electrolyte. We extended the evaluation to the role of the electrolyte on the performance of cathodic and anodic processes of a Mn-based PBA. Ex-situ and operando chemical characterization were coupled to support the microelectrochemical results.},
