近年來，普魯士藍被用作充電電池的正極材料。普魯士藍有兩種獨立的氧化還原過渡金屬元素。可儲存鋰離子，進行電池充放電反應，且易於合成，成本低，壽命長，具有高功率特性。 K-CoCo和Na-FeFe普魯士藍納米粒子採用共沉澱法製備，K-CoCo採用50℃共沉澱溶液製備。 Na-FeFe 分別在 85°C 下通過共沉澱溶液製備。使用 X 射線衍射分析樣品的晶體結構和化學成分。 50℃共沉澱溶液製備的K-CoCo樣品粒徑為41 nm； 85℃共沉澱溶液製備的Na-FeFe樣品粒徑為59nm。在極片K-CoCo的生產過程中添加了鎳和銦兩種納米顆粒。同時，在正極片Na-FeFe的製作過程中添加鎳和銀兩種納米顆粒，將納米顆粒和普魯士藍混合均勻，製成電池極片。將41 nm K-CoCo普魯士藍和59 nm Na-FeFe普魯士藍製成電池，並討論了電池的充放電循環效率。分別在 41 nm K-CoCo 和 59 nm Na-FeFe 中添加鎳、銀和銦納米顆粒，以測試添加納米顆粒的電池的充放電循環效率。 59 nm Na-FeFe 添加劑添加不同比例（10%、25%、35%）的鎳和銀納米顆粒電池以不同電流 0.03 mA 和 0.015 mA 充放電，添加 41 nm K-CoCo 13% 的納米粒子在不同電流（0.03 mA、0.015 mA 和 0.007 mA）下循環測試

In recent years, Prussian blue was used as a cathode material for rechargeable batteries. Prussian blue has two independent redox transition metal elements. It can store lithium ions, perform battery charge and discharge reactions, and is easy to synthesize, Low cost, has a long life, and has high power characteristics. K-CoCo & Na-FeFe Prussian blue nanoparticle was prepared by co-precipitation method, and K-CoCo was prepared by co-precipitation solution at 50°C. Na-FeFe was prepared by co-precipitation solution at 85°C, respectively. Use X-ray diffraction to analyze the crystal structure and chemical composition of the sample. The K-CoCo sample prepared by the 50°C co-precipitation solution has a particle size of 41 nm; the Na-FeFe sample prepared by the 85°C co-precipitation solution has a particle size of 59 nm. Two kinds of nanoparticles of nickel & indium are added during the production of the pole piece K-CoCo. Meanwhile, two kinds of nanoparticles of nickel & silver are added during the production of the positive pole piece Na-FeFe the nanoparticles and Prussian blue are uniformly mixed to produce the battery pole piece. The 41 nm K-CoCo Prussian blue and 59 nm Na-FeFe Prussian blue were made into batteries, and the battery charge-discharge cycle efficiency was discussed. The 41 nm K-CoCo and 59 nm Na-FeFe were added with nickel, silver, and indium nanoparticles, respectively, to test the charge-discharge cycle efficiency of the battery with the added nanoparticles. The 59 nm Na-FeFe add with different percentages of nanoparticles (10%, 25%, 35%) of nickel and silver nanoparticle batteries were charged and discharged with different currents 0.03 mA & 0.015 mA, and the 41 nm K-CoCo the added 13% nanoparticles were cyclically tested at different currents (0.03 mA, 0.015 mA & 0.007 mA)
