We report a comparison of different common synthetic strategies for preparation of Prussian blue analogues (PBA). PBA are promising as cathode material for a number of different battery types, including K-ion and Na-ion batteries with both aqueous and non-aqueous electrolytes. PBA exhibit a significant degree of structural variation. The structure of the PBA determines the electrochemical performance, and it is, therefore, important to understand how synthesis parameters affect the structure of the obtained product. PBA are often synthesized by co-precipitation of a metal salt and a hexacyanoferrate complex, and parameters such as concentration and oxidation state of the precursors, flow rate, temperature and additional salts can all potentially affect the structure of the product. Here, we report 12 different syntheses and compare the structure of the obtained PBA materials.

我们报告了普鲁士蓝类似物（PBA）的制备的不同常见合成策略的比较。PBA有望用作许多不同类型电池的正极材料，包括同时具有水性和非水性电解质的K离子和Na离子电池。PBA表现出很大程度的结构变异。PBA的结构决定了电化学性能，因此，重要的是了解合成参数如何影响所得产物的结构。PBA通常是通过金属盐和六氰基铁酸盐配合物的共沉淀来合成的，参数（例如前体的浓度和氧化态，流速，温度和其他盐）都可能会影响产品的结构。这里，
