摘要

矽因擁有最大的理論電容量而被看好可以取代石墨成為新一代鋰離子電池的陽極材料。然而，充放電過程中大量的體積變化是造成電池衰退的主因。近幾年來，黏著劑在矽基陽極上所扮演的角色開始受到重視。本研究選取了幾種目前用在矽基陽極上電性表現較好的黏著劑，以相同的條件做電性測試，並以其他性質測試做輔助，目的是找出最適合矽基陽極的黏著劑。

Silicon, having the highest theoretical energy capacity, is an attractive anode material for next-generation lithium-ion batteries. However, because of huge volume changes during battery operation, silicon-based anode has yet to be commercialized. In the past decade, binder, an electrochemically inactive material, has been noticed to play an important role in battery performance. Many researchers were making a lot of effort in searching for new binders, but these binders were being tested under different conditions by different groups. This study aimed to make a comparison between different types of binders, trying to find out the most suitable binder for silicon-based anodes.
