摘要:	鋰電池的使用自二十一世紀以來規模已經是越加地廣泛與普及，降低其製造成本與對環境所造成的損害是近年來多方努力研究的主要方向之一。本實驗嘗試兩種結構相似且在人類歷史上已被運用數千年之久的天然染料，茜紅與靛藍，將其作為材料製作成鋰電池的電極並探討其效率，主要分成兩大部分。第一部份為對材料進行探討，利用X光繞射來研究樣品，再經由GSAS分析樣品，得出茜紅與靛藍的粒徑大小並確定其實際結構。第二個部分為製作成電池並對於電池充放電循環效率進行嘗試與探討，第一個嘗試為改變電極本身基底的金屬極片材料，比較電池在銅箔與鋁箔不同電極基底材料下效率的差異。第二個嘗試為在極片製作時額外添加鎳奈米顆粒，將鎳奈米顆粒與樣品均勻混和製作成電池電極，比較電池在有無摻雜鎳奈米顆粒下效率的差異。經結果可看出使用銅箔作為電極基底的材料時與鋁箔相比而言，大致上對茜紅與靛藍鋰電池充放電表現都有提升的效果，且不會干擾材料進行電化學反應，然而在使用鋁箔作為電極基底的材料時會干擾靛藍進行電化學反應。接著以摻雜與未摻雜相比而言，大致上對茜紅與靛藍鋰電池充放電表現都有提升的效果，然而在鋁箔材料下添加鎳奈米顆粒對於茜紅鋰電池充放電表現則是有降低的效果。 ;The use of lithium batteries has become more widespread and popular since the 21st century, and reducing its manufacturing costs and damage to the environment has been one of the main directions of many efforts in recent years. In this experiment, we tried two natural dyes that are similar in structure and have been used for thousands of years in human history, alizarin and indigo, and used them as materials to make lithium battery electrodes and explore their efficiency. They are mainly divided into two parts. The first part is to discuss the material, use X-ray diffraction to study the sample, and then analyze the sample through GSAS to obtain the particle size of alizarin and indigo moreover determine the actual structure. The second part is to make a battery and try as well as look into the battery charge and discharge cycle efficiency. The first attempt is to change the metal foil material of the electrode itself, and compare the efficiency of the battery under the different electrode substrate materials of copper foil and aluminum foil. The second attempt is to dope nickel nanoparticles during the production of the battery electrode, uniformly mix the nickel nanoparticles with the sample to make a battery electrode, and compare the efficiency of the battery with or without nickel nanoparticles. The results show that when copper foil is used as the electrode , compared with aluminum foil, it generally improves the charging and discharging performance of alizarin and indigo lithium batteries, and does not interfere with the electrochemical reaction of the sample. However, when aluminum foil is used as the electrode, it will interfere with the electrochemical reaction of indigo. Then compared with the doped and undoped, the charging and discharging performance of the alizarin and indigo lithium batteries are generally improved. However, in the case of aluminum foil electrodes, doped nickel nanoparticles have a lowering effect on the performance of the alizarin lithium battery.
