摘要:	近年來普魯士藍作為可重複充放電電池之陰極材料，普魯士藍具有兩個可獨立氧化還原的過渡金屬元素，及開放式的穩定三維框架，可用來儲存鋰離子並進行電池充放電反應，容易合成、低成本、長壽命、重量輕和高功率的特性。以共沉澱法製作K-CoCo普魯士藍奈米顆粒，分別以70°C及0°C共沉澱溶液製作K-CoCo。利用X光繞射來分析樣品晶體結構以及化學組成成分，以70°C共沉澱溶液製作K-CoCo樣品K0.38Co[Co(CN)6]0.75[(H2O)6]0.25?0.38H2O粒徑為101 nm；以0°C共沉澱溶液製作K-CoCo樣品K0.52Co[Co(CN)6]0.72[(H2O)6]0.28?0.34H2O，粒徑為61 nm。於極片製作時添加鎳、銀、銦三種奈米顆粒，將奈米顆粒與普魯士藍均勻混和製作成電池極片。將101 nm K-CoCo普魯士藍及61 nm K-CoCo普魯士藍製作成電池並探討電池充放電循環效率。將101 nm K-CoCo及61 nm K-CoCo分別添加鎳、銀、銦奈米顆粒，測試添加奈米顆粒的電池充放電循環效率。使用小電流0.015 mA對61 nm K-CoCo與添加鎳、銀奈米顆粒電池充放電循環，將101 nm K-CoCo及61 nm K-CoCo與添加奈米顆粒分別以不同電流進行循環測試。使用銅箔作為61 nm K-CoCo與添加奈米顆粒電池極片，並探討電池充放電循環效率。將101 nm K-CoCo與添加銀奈米顆粒極片製備時外加電場，測試電池充放電循環效率。將101 nm K-CoCo與添加奈米顆粒外加磁場，測試電池充放電循環效率。;In recent years, Prussian blue has been used as a cathode material for rechargeable batteries. Prussian blue has two independent redox transition metal elements and an open and stable three-dimensional framework. It can be used to store lithium ions and perform battery charge and discharge reactions, and is easy to synthesize , Low cost, long life, light weight and high power characteristics. K-CoCo Prussian blue nanoparticle was prepared by co-precipitation method, and K-CoCo was prepared by co-precipitation solution at 70°C and 0°C respectively. Use X-ray diffraction to analyze the crystal structure and chemical composition of the sample, The K-CoCo sample prepared by the 70°C co-precipitation solution has a particle size of 101 nm; the K-CoCo sample prepared by the 0°C co-precipitation solution has a particle size of 61 nm. Three kinds of nano particles of nickel, silver and indium are added during the production of the pole piece, and the nano particles and Prussian blue are uniformly mixed to produce the battery pole piece. The 101 nm K-CoCo Prussian blue and 61 nm K-CoCo Prussian blue were made into batteries and the battery charge-discharge cycle efficiency was discussed. The 101 nm K-CoCo and 61 nm K-CoCo were added with nickel, silver, and indium nano-particles, respectively, to test the charge-discharge cycle efficiency of the battery with the added nanoparticles. The 61 nm K-CoCo and nickel and silver nanoparticle batteries were charged and discharged with 0.015 mA, and the 101 nm K-CoCo and 61 nm K-CoCo and the added nanoparticles were cyclically tested at different currents. Using copper foil as 61 nm K-CoCo and adding nanoparticle battery pole pieces, and discussing the battery charge-discharge cycle efficiency. When preparing 101 nm K-CoCo and silver nanoparticle pole pieces, an electric field and a magnetic field were applied to test the battery charge-discharge cycle efficiency.
