本實驗使用反應沉澱法製備K-Fe-Fe相的普魯士藍，透過改變螯合物添加濃度製備出Cubic或是Monoclinic結構之樣品，製備出的樣品將會研究其晶體結構、磁性行為、拉曼散射以及進行鋰離子電池的組裝。 組裝完成後的電池送入充放電測試儀中進行充放電，並且觀察其結構改變對充放電的影響，Cubic結構的樣品有較好的起始電容量，而Monoclinic結構則是擁有較佳的充放電循環壽命。 ;In this experiment, Prussian blue of K-Fe-Fe phase was prepared by reactive precipitation method. The samples of cubic or monoclinic were prepared by changing the concentration of chelate. The prepared samples will study their crystal structure, magnetic behavior, raman scattering and assembly of lithium-ion batteries. After the completion of the assembly of the battery into the tester charge and discharge, and observe the structural changes on the impact of charge and discharge, Cubic structure of the sample has a good starting capacity, and monoclinic structure is to have a better charge discharging cycle life.
