隨著近幾年來對於能量儲存的需求，對於電池的相關研究數量也在近數十年間蓬勃發展，其中的鋰電池配合類普魯士藍的相關研究也得到不小的關注。相較於以往的鋰電池，普魯士藍除了有較低汙染和成本，其特殊的晶格物理性質也時期有優良的理論電容量和循環壽命。
本系列實驗中，以共沉澱法來製備普魯士藍，並在其間的滴定溫度分別控制在〖25〗^° C、〖50〗^° C、〖70〗^° C、及〖85〗^° C，所製備出的普魯士藍平均粒徑隨溫度提升而增加，依序為12 nm、21 nm、37 nm和54 nm。之後，將其製成電池的陰極極片並將之製成鈕扣電池。此外，在製造極片的途中也會加入適量的奈米鎳金屬，以期增加電池導電能力來增加電池的效能。
根據本文的電池，主要可以發現當普魯士藍鋰電池添加奈米鎳時，電容量皆會有明顯的下降，且添加越多的奈米鎳會得到更差的電容量。經由微分圖可以看出當添加奈米鎳時，Fe-C鍵反應會相對於Fe-N鍵反應來的不明顯，因而有電容量的差距。另外，當使用較低電流對添加奈米鎳的普魯士藍電池進行充放電時，電池的放電電容量會提升，但該提升對於Fe-N鍵較明顯，而Fe-C鍵反應仍不顯著。

Since the necessity of the batteries, the study of the prussian blue(PB) battery has increased fro decades of years because of its low cost, environmental friendly, high theoretical capacity, and long cycle life. Such of the features are caused by its special structure, which provides the space to storage lithium ions.
In this study, the co-precipitation method was used to produce PB. The difference is that the temperature are controlled to four different temperature during the titration process, causing the different particle size of PBs. The X-ray is also used to analyze the difference of particle size. After that, the produced, different size PBs are made into batteries to analyze. Also, nano size of nickel are added to the PB to see if the nickel will affect the batteries.
In this work, we found out that PB batteries with nano size of nickel will have worse full specific capacity when comparing with PB battery. Also, the more nano size of nickel is added, the worse the capacity is. This difference may caused by Fe-C reaction at 3.3 V.
