本研究以酚醛樹脂進行多重孔洞碳材之合成，活化參數包括為活化劑、模板及溫度，並且將所合成之高比表面積且孔洞分佈寬廣的多重孔洞碳材組裝成鈕扣式超級電容器。以酚醛樹脂為起點，將碳前驅物與活化劑及模板在濕式狀態下混合均勻之後進入烘箱固化，再經由高溫活化反應即可得到比表面積達 2006 m2/g 之碳材料，除了避免乾式法之粉塵之外也可以得到活化均勻的碳材料。
酚醛樹脂碳材料基於化學活化法製備，僅單純透過活化劑量即可控制比表面積(339 ~ 1016m2/g)，在加入模板之後根據氮氣吸附脫附圖以及孔徑分布圖的變化得知在活化過程加入奈米碳酸鈣能夠有效擴大孔徑，藉由加熱溫度控制一步驟活化以及兩步驟活化(碳化及活化)影響比表面積。除了比表面積之外，透過活化劑比例以及活化時間得到不同石墨化程度的活性碳，證明活化劑氫氧化鉀的活化機制。
將不同比表面積以及不同石墨化程度的碳材料應用於超級電容系統；首先進行參數優化，包括隔離膜以及面積質量擔載；並且將上述成功控制比表面積以及石墨化程度的碳材料組裝成二極式鈕扣電容。透過循環伏安法的圖形以及計時電位法的電壓降得知兩種碳材料性質對於超級電容器之影響，結合電化學阻抗頻譜發現表面積以及石墨化程度會大幅影響電雙層結構的阻抗，因此改變倍率性能(rate capacity)。最佳化電容參數之後，在 1.0 M TEABF4/PC 的有機電解液中可以達到 117 F/g 的比電容值( scan rate = 2 mV/s )，並且在高掃描速率下( 200 mV/s )仍然可維持 79 % 之倍率性能。
本研究透過濕式活化法成功製備酚醛樹脂基多重孔洞碳材料，也將碳材料應用於儲能電容器；將無金屬殘留的酚醛樹脂作為碳前驅物能夠完全排除金屬雜質，並且證明比表面積、石墨化程度等材料基本性質對於電雙層電容的影響，提供高性能超級電容器材料的合成手法。

Porous carbons are nowhere to be seen nowadays, due to their many unique properties, such as good conductivity, high surface area and an abundance of active sites, there are involved in many important applications. In this study, we propose a method to synthesize multiporous carbons (MPCs) with high specific surface area and wide pore sizes distribution using Phenol Forlamdehyde Resin.
The high specific surface area (339 ~ 1016 m2/g) can be achieved by the activation reagent alone based on the chemical activation method, while the addition of nano-calcium carbonate during the activation process is known to be effective in expanding the pore size based on the changes in the nitrogen adsorption and desorption measurement and the pore size distribution diagrams after activation, the specific surface area is also affected by the thermal process, which is proved by the one-step activation and two-step activation (carbonization and activation). In addition to the specific surface area, the stoichiometry and the activation time are used to obtain activated carbon with different graphitization levels, so the activation mechanism of the activator potassium hydroxide is known.
Carbon materials with different specific surface areas and graphitic structure were applied to the supercapacitor system; firstly, the parameters were optimized, including the saparator, mass loading and the carbon materials with successfully controlled specific surface areas and graphitization. The effect of carbon material properties was determined by cyclic voltammetry and chronoamperometry. Combined with electrochemical impedance spectroscopy, it was found that surface area and graphitization significantly affected the impedance of the electrical double-layer structure, so the rate capacity of the electrodes was changed. After optimizing the capacitance parameters, a specific capacitance value of 117 F/g (scan rate = 2 mV/s) was achieved in 1.0 M TEABF4/PC electrolyte, and the rate capacity of 79% was maintained at a high scan rate (200 mV/s).
