本研究探討三聚硫氰酸與雙馬來醯亞胺共聚合利用非恆溫示差掃描熱量分析儀(DSC)的方式了解其中以何種反應進行聚合反應，並且使用熱重量分析(TGA)測試其熱裂解溫度模擬當電池發生熱失控時添加劑會有何影響，使用上述兩者作為熱化學分析，同時使用核磁共振光譜分析(NMR)分析其材料結構鑑定作為化學分析。
本研究同時將以上聚合物作為鋰離子電池正極添加劑，分析對於正極材料LiNi0.5Co0.2Mn0.3O2的影響，分析方法包括使用正極辦電池充放電測試(C/DC)、交流阻抗圖譜分析(EIS)、循環伏安法分析(CV)等電化學反應測試，以了解添加劑的電化學性質，並通過掃描式電子顯微鏡(SEM)、能量分散光譜(EDS)了解充放電過後的電極極片表面型態極組成。最後再使用示差掃描熱量分析儀(DSC)了解電極材料的熱穩定性。經過電性測試比較有/無添加劑的電極極片之間的差異得以了解添加劑的應用在鋰離子電池正極材料上所造成的結果。
在本研究中的實驗結果中於正極材料LiNi0.5Co0.2Mn0.3O2中添加BMI/TCA
(1.5:1)0.5%添加劑可以有效改善正極半電池於各式實驗條件下極化現象以及電池電容量，此外從循環伏安法(CV)能夠看出動力學對於電池的影響，添加BMI/
TCA(1.5:1)0.5%中改善極化現象，以及常溫和高溫下循環壽命圖能夠看見此添加劑的電性較為優秀，從SEM觀察出充放電過後有明顯的一層塗層膜，EDS中也明顯看出碳的增加表明了BMI加入的結果。DSC熱穩定性也能夠看出添加入添加劑後能夠有效的降低放熱量，根據本研究結果，添加BMI/TCA(1.5:1)0.5%為最穩定的添加劑。

This study investigated the copolymerization of trithiocyanate(TCA)and N,N- bismaleimide-4,4-diphenylmethane(BMI) using a non- isothermal temperature differential scanning calorimeter (DSC) to understand the reaction in which to carry out the polymerization and to test it by thermogravimetric analysis (TGA). The thermal cracking temperature simulates the effect of the additive on the thermal runaway of the battery. Both of the above were used as thermochemical analysis, and the material structure identification was analyzed by nuclear magnetic resonance spectroscopy (NMR) as a chemical analysis.
In this study, the above polymers were used as positive electrode additives for lithium ion batteries, and the influence on the positive electrode material LiNi0.5Co0.2Mn0.3O2. was analyzed. The analysis methods included the use of positive electrode battery charge and discharge test (C/DC) and AC impedance spectroscopy (EIS). Electrochemical reaction tests such as cyclic voltammetry (CV) to understand the electrochemical properties of the additive, and to understand the surface of the electrode state composition after charge and discharge by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Finally, the differential scanning thermal analyzer (DSC) is used to understand the thermal stability of the electrode material. The difference between the electrode with/without additives was compared by electrochemical testing to understand the results of the application of the additive on the positive electrode material of lithium ion batteries.
In the experimental results in this study, BMI/TCA(1.5:1) 0.5% was added to the positive electrode material LiNi0.5Co0.2Mn0.3O2.It can effectively improve the polarization of the positive half-cell under various experimental conditions and the battery capacity. In addition, the effect of kinetics on the battery can be seen from cyclic voltammetry (CV), adding BMI/TCA (1.5:1) The improvement of polarization in 0.5%, and the cycle life diagram at normal temperature and high temperature can be seen that the electrical properties of this additive are excellent. From the SEM observation, there is a clear coating film after charge and discharge, and EDS is also obvious. It is seen that the increase in carbon indicates the result of BMI addition. The thermal stability of DSC can also be seen to effectively reduce the heat exothermic after the addition of additives. According to the results of this study, BMI/TCA (1.5:1) 0.5% was added as the most stable additive.
