結構型超級電容器(SSC)因其高比電容、優異的機械強度及長循環壽命，近年來備受關注，並成為便攜式設備、電動車與航太產業中極具發展潛力的儲能技術。本研究針對一種新型 SSC 進行探討，其電極採用雙向編織碳纖維，介電層則選用雙向編織玻璃纖維，電解液使用 PVA-KOH 鹼性聚合物，基材則由環氧樹脂與硬化劑組成。透過真空輔助樹脂轉注成型(VARTM)製作樹脂含量 15wt% 之 SSC，旨在製作出電化學性質及機械性質兼具之成品。為了延長 SSC 之使用壽命，本研究進一步開發封裝技術，採用雙層碳纖維與單層玻璃纖維預浸料作為封裝材料，並利用銅箔與導電銀膠將電極延伸，以提升機械強度並減少水分流失，從而提高 SSC 之穩定性。此外，為提升 SSC 之應用效能，亦開發出電容器串/並聯之封裝方式。實驗結果表明，透過對 SSC 進行封裝，成功達到於 50 日仍保有 97.2% 的比電容值，展現出優異之長期穩定性，進一步分析發現，串聯封裝可有效提升電容器之最大操作電壓，而並聯封裝則可提高總電容量，並顯著降低等效串聯電阻(ESR)之影響。綜上所述，本研究成功開發出穩定成型的 SSC 封裝製程，有效延長 SSC 的使用壽命，同時，提出了有效的電容器串/並聯方式，提升了其應用的多樣性，這將解決 SSC 在過去研究上所面臨到時間的挑戰，並提升實際運用之可行性。

This study investigates structural supercapacitors (SSC) with high specific capacitance, fast charge-discharge capability, and enhanced mechanical strength. The SSC utilizes woven carbon fiber electrodes, an alkaline electrolyte, and are fabricated using vacuum-assisted resin transfer molding (VARTM) with a resin content of 15 wt%, achieving a balance between electrochemical and mechanical performance. To improve durability, a dual-layer carbon fiber and single-layer glass fiber prepreg encapsulation is introduced, with copper foil and conductive silver paste extending the electrodes. This enhances mechanical integrity and minimizes moisture loss. Encapsulation enables 97.2% capacitance retention after 50 days, while series connections increase operating voltage, and parallel connections increase total capacitance while reducing equivalent series resistance (ESR). This study establishes a stable SSC encapsulation process that extends lifespan and improves practical feasibility, addressing key challenges in SSC development.
