普鲁士蓝类似物及其制备方法、阴极材料和应用
摘要：
本发明涉及一种普鲁士蓝类似物及其制备方法、阴极材料和应用。普鲁士蓝类似物的制备方法，包括以下步骤：以水为溶剂，将铁氰化钾和硝酸锌进行共沉淀反应，得到反应液；将反应液静置，得到沉淀物；及将沉淀物干燥，得到化学式为K2Zn3[Fe(CN)6]2的普鲁士蓝类似物。上述普鲁士蓝类似物的制备方法操作简单，且能够得到晶粒大小在300nm左右、循环稳定性较好的普鲁士蓝类似物。
摘要（英）：

The invention relates to prussian blue analogue, a preparation method thereof, a cathode material and application. The preparation method of the prussian blue analogue comprises the following steps: taking water as a solvent, carrying out co-precipitation reaction on potassium ferricyanide and zinc nitrate to obtain a reaction solution; standing the reaction solution to obtain a precipitate; and drying the precipitate to obtain the prussian blue analogue with the chemical formula of K2Zn3 (Fe (CN) 6) 2. The preparation method of the prussian blue analogue is simple to operate, and the prussianblue analogue with the grain size of about 300 nm and good cycling stability can be obtained.
