dc.description.abstract本研究將循環經濟和仿生材料概念帶入超級電容的系統中,利用奈米複合材料其包含蒙脫土(MMT)、聚乙烯醇(PVA)、聚二氧乙基噻吩:聚苯乙烯磺酸(PEDOT:PSS)和二氧化釕(RuO2)奈米粒子,來製造環保全固態可撓式超級電容器。透過X光繞射、X光顯微術、掃描式電子顯微術、X光吸收光譜、力學測試、接觸角和電化學分析有系統探討此環保全固態可撓式超級電容器之結構-性質-性能之關係。其中,我們分別利用蒙脫土吸附釕金屬離子於層狀結構內的特性,透過方法A和B合成二氧化釕(RuO2)奈米粒子,而其奈米粒子尺寸與分布也分別導致蒙托土形成紙牌屋(House of card)結構以及仿珍珠貝 (Nacre-like)結構於電極內部。我們發現紙牌屋結構電極具有較好的電化學性能,但是其力學性質則稍差於仿珍珠貝結構電極。亦發現紙牌屋結構電極其電容值可達568 mF/cm2 (71F/g),也優於過去文獻曾報導過RuO2全固態可撓式超級電容器。此外,其能量密度和電流密度分別為40.6 Wh/cm2 (10.2Wh/kg)和4 mW/cm2 (1000W/kg)。透過回收再製後之超級電容器其效能可達至原電容器之70%,成功落實了循環經濟之概念。zh_TW
dc.description.abstractIn this study, we introduce two concepts of circular economy and biomimetic materials into nanocomposite electrodes for fabricating all-solid-state flexible supercapacitors (ssFSCs). The designed nanocomposites were composed of montmorillonite (MMT), ruthenium dioxide nanoparticles (RuO2 NPs), polyvinyl alcohol (PVA) and Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). We investigated structure-property-performance relationships of the ECO-firendly all-solid-state flexible supercapacitor using X-ray diffraction, transmission X-ray microscope, X-ray absorption spectroscopy, electron microscope, testing machine, contact angle and potentiostat–galvanostat. Attributing to RuO2 NPs size and their distribution in the structural electrodes, a house-of-cards structure and a nacre-like structure were respectively obtained from synthesized method A and method B. We found that the house-of-cards structural ssFSC features higher performance of storage energy but lower mechanical strength than the nacre-like structural ssFSC. The capacitance of the house-of-cards ssFSC is up to 568 mF/cm2 (71 F/g), which is also better than the RuO2-based ssFSCs. Furthermore, their maximum energy and power densities are respectively calculated as 40.6 Wh/cm2 (10.2Wh/kg) and 4 mW/cm2 (1000W/kg). Concerning recycling of electrodes for the circular economy, storage energy performance of the recycled devices can perform about 70% of the original devices.en_US
