本研究的目的利用低成本(Sol-gel)的方式製備不同金屬添加物石墨稀可撓式超級電容，利用循環伏安法進行電容電量量測，進行反覆彎曲測試，探討電容元件疲勞特性。我們成功製備可撓式銀、鎳及錳金屬添加物石墨烯超級電容器，其比電容值以添加銀最佳，其次為鎳，最後為錳。此外，SEM觀測結果顯示金屬顆粒會在石墨烯表面析出，且析出顆粒形狀銀和鎳為圓球狀;錳為不規則狀，顆粒大小：鎳<銀<錳。
反覆彎曲測試的結果顯示每一種金屬添加物添加克數越多，其比電容值對彎曲疲勞的抵抗性(比電容的下降率)越佳，其中以錳為最佳，銀與鎳次之。綜合以上結果，如果考慮元件電性可選擇銀作為金屬添加物，但如考慮機械抗彎曲疲勞特性，則可選擇錳作為金屬添加物，這些可做為元件設計的重要參考。

In this paper, several flexible metals/graphene Super-capacitors were fabricated using sol-gel methodology and their electric performance were characterized by the cyclic voltammetry measurement and the bending test. In our research, we used silver nitrate (AgNO3), nickel nitrate Ni (NO3)2, manganese nitrate and Mn (NO3)2‧6H2O as the additions. Each of them dissolved in deionized water (DI Water), and we also added some carbon blacks to enhance their conductivity. The silver additions presents the better performance than other two metals ones. We also experimented different angles by using the micro-tensile test tensile machine, discussing the performance of the electrochemistry double layer capacitance (EDLC) current-voltage relationship. Furthermore, using scanning electron microscope (SEM) we could observe the surface condition and the Specific Surface Area of our EDLC.
Repeated bending test shows that the more metal additions that represent the higher electric performance to result that the resistance of bending is better. Manganese oxide is the best one to all additions. Above all, if we consider the electric performance only we could choose the silver addition, but if we consider the bending resistance only we could choose Manganese oxide to be the addition. As the results be they could be the guideline of selecting the better materials to fabricate the Super-capacitors.
