Abstract:	本篇論文總共分為四個章節。第一章為總體序論，簡單介紹了電化學儲能、無機和有機材料作為電池電極的優缺點、三種有機聚合物材料(聚三苯胺 (PTPA)、聚醯亞胺 (PIs)、聚醯胺 (PAs))的性能以及研究動機。第二章評估了基於二氰基三苯胺的聚醯亞胺作為鋰離子電池有機陰極和陽極材料的電化學性能以及 TPA-PMPI 同時作為活性材料和聚合物粘合劑的雙重功能。第三章，我們測試了基於二氰基三苯胺的聚醯胺作為鋰離子電池的有機陽極材料，研究它們的電化學性能以及 DiCN-ether 同時作為活性材料和聚合物粘合劑的雙重功能。第四章為結論和研究展望。研究並比較了這些基於二氰基三苯胺的聚醯亞胺和聚醯胺電極材料的反應電壓、放電容量、速率穩定性、反應機制和電化學電阻。這些聚合物有機材料不僅在電解質中表現出優異的穩定性，並且由於可逆的 Li+ 插入/脫嵌能力，還具有很高的庫侖效率。由於具有出色的比容量和長時間循環壽命，這些基於二氰基三苯胺的聚合物被認為是具有潛力的下一代鋰離子電池有機電極材料。 ;This thesis has been divided into four chapters. Chapter 1 is general introduction, simply introduced electrochemical energy storage, advantages and disadvantages of inorganic and organic materials as battery electrodes, properties of three kinds of organic polymer materials (polytriphenylamine, polyimides, polyamides) and the research motivation. Chapter 2 evaluated electrochemical performances of dicyanotriphenylamine-based polyimides as organic cathode and anode materials for lithium-ion battery and the dual functional capability of TPA-PMPI as both active material and polymer binder simultaneously. Chapter 3, we tested dicyanotriphenylamine-based polyamides as organic anode materials for lithium-ion battery to investigate their battery performances as well as the dual functional capability of DiCN-ether as both active material and polymer binder simultaneously. Chapter 4 is the conclusion and research outlook. The reaction voltages, discharge capacity, rate stability, reaction mechanism and electrochemical resistance of these dicyanotriphenylamine-based polyimides and polyamides were investigated and compared. These polymer organic materials not only showed excellent stability in electrolytes, but also got high coulombic efficiency due to the capability of reversible Li+ insertion/de-insertion. Owing to the outstanding specific capacity with long term cycling life, these dicyanotriphenylamine-based polymers are considered as promising organic electrode materials for next generation Li-ion batteries.
