近年來普魯士藍材料被發現不但具有鋰電池方面的應用潛力，在另一種更為新穎的鈉電池方面亦然，因而成為研究焦點，原因在於該材料提供足夠大的晶格空隙，使得鋰離子得以進行嵌入遷出，而原子半徑更大的鈉離子亦可。本論文中的實驗樣品為A-Ni-Co(A=K,Rb) 類普魯士藍，論文內容主要分成兩大部分。 第一部份為A-Ni-Co PBA物理特性分析。藉由X光繞射，可以得知額外添加KCl可以做出來的普魯士藍粒徑比較大，額外添加RbCl則是能在PBA中心填入Rb+。且由K-Ni-Co PBA和Rb-Ni-Co PBA比較則得出中心位置原子越大則整體結構也有放大的效果。再由XPS分析得知K-Ni-Co PBA和Rb-Ni-Co PBA都是以Ni2+和Co2+/3+組成，惟Rb-Ni-Co PBA之Co2+：Co3+的比值比K-Ni-Co PBA高。由拉曼光譜則得知三種樣品有相同之鍵結模式，且都比Fariba Safizadeh所做出之結果往更高能量位移，顯現出此樣品有電荷轉移的現象 第二部份則為A-Ni-Co PBA電化學特性，分成全充放電測試結果討論及外加磁場對A-Ni-Co PBA二次電池之充放電影響探討。由全充放電結果中可看到Rb-Ni-Co PBA衰退最不明顯，K-Ni-Co PBA2 電容量最大。而外加磁場改變下，極片混合Ni能讓電容量短時間上升。 ;Prussian Blue (PB) or Prussian Blue analog (PBA) attracts many attentions recently for it’s application potential not only in the field of Lithium battery but also in Sodium battery, a novel one compared to the former, because it offers large enough voids at the center portion of the lattice to accommodate Lithium or Sodium ions. In this thesis, the A-Ni-Co PBA (A=K , Ni) has been studied and divided into two parts. In the first part is determination of physical property. By added additional Potassium chloride in production process can make a bigger particle size sample.And if we added Rubidium chloride in production process, we can get the PBA sample that it’s center ionic is rubidium ion. And cause rubidium ion is larger than chloride ion, PBA sample with Rb in center usually crystal size is bigger than the sample that K in the center. By XPS analysis knows that both K-Ni-Co PBA1 and Rb-Ni-Co PBA were contained with Nickel(II), Cobalt(II), Cobalt(III). But two sample has different Co3+/Co2+ prorprtion. Rb-Ni-Co PBA has higher Co3+/Co2+ prorprtion then K-Ni-Co PBA1. In Raman spectroscopy shows that three sample has similar chemical bonding, and all of then are has higher energy than Fariba Safizadeh’s data shows that these sample has charge transfer that drive then to higher energy bonding. The second part is A-Ni-Co electrochemistry analysis. In this part has two testing, one is full charge/discharge test, second testing is applied magnetic field effect to battery performance. In full charge/discharge test shows that Rb-Ni-Co PBA has highest anti-decilne ability. K-Ni-Co PBA shows that this sample has highest capacity. In applied magnetic field effect to battery performance test shows changing applied magnetic field will increase capacity in the short time when nixed 10% Ni nano powder in the electrodes production process.
