Prussian Blue Analogues (PBAs) provide a promising look into the future of battery technology; their low cost and facile creation grants the opportunity for a commercially viable battery. In addition, their components consist of earth-abundant elements, which may potentially lead to a green battery material, an area of growing importance. The modification process in which the PBA forms may be carried out by one of two techniques: the standard cyclic voltammetry (CV) technique consists of performing cyclic voltammetry in a modification solution for a set number of cycles, whereas the dipping technique involves submerging the substrate in the solution for a specific amount of time. In order to better understand the time dependence of spontaneous PBA formation, substrates were dipped in modification solution for varying amounts of time ranging from 15 seconds to 600 seconds. Additionally, hydrolysis is believed to occur and affect charge storage measurements during characterization. To better understand the effect of hydrolysis on characterization measurements, some samples were tested in 0.1 M sodium perchlorate (NaClO4) dissolved in both an aqueous solution and a non-aqueous, acetonitrile-solvent (CH3CN) solution. Comparisons between the data from both solutions may lead to a better understanding and accounting of the effects of water when characterizing aqueously.
