目前的錳氧化物薄膜電極不論以溶膠-凝膠法或陽極沈積法所製備的電極材料皆為非結晶構造，使用在電解液下反應時，由於結構鬆散，往往易有錳氧化物薄膜溶損之行為發生，需另外藉由熱處理程序才能改善其電化學穩定性，但其比電容值易因熱處理溫度的增加而減小。基於此觀點考量下，若能將錳氧化物電極材料製成比表面積大且為結晶性的錳氧化物薄膜，則將之作為電極材料時，應可提升其比電容值及其電化學特性。
　　本研究目的旨在以水熱法陽極沈積錳氧化物於鈦片電極基材上，並將之作為超高電容器之電極，檢討水熱處理條件對錳氧化物電極的電化學特性及其表面積對電容量之影響。在電化學特性分析方面，主要是以循環伏安法於0.1M Na2SO4溶液中進行擬電容行為測試及比電容量之評估。
　　實驗結果顯示錳氧化物薄膜電極在100℃水熱溫度下，陽極沈積0.5分鐘，具有最佳的比電容量。在水熱環境下進行之陽極沈積之錳氧化物薄膜，經循環伏安測試其電化學特性，可看出其循環伏安曲線是隨著掃瞄圈數的增加，而逐漸變大，顯示在水熱環境下成長作為電極表面的錳氧化物薄膜其表面活性物質在電解液中未能瞬間完全參與反應所致。

　　No matter the electrode material of manganese oxides thin films made by sol-gel or anodic deposition are not crystallization, and manganese oxides thin films are easy to be dissolved under the reaction of electrolyte. It is helpful to stabilize the electroanalysis by the process of heat treatment, but the specific capacitance will decrease by the increase of temperature. According to the above, if electrode of manganese oxides could made to be crystallinity and larger than the measure of surface, it will strengthen the property of specific capacitance and electroanalysis.
　　My research is to anodic deposition manganese oxides on electrode titanium by hydrothermal method, and be used as the electrode of supercapacitor to discuss the effect of electric capacity by the electrode of manganese oxides property of electroanalysis and the measure of surface under anodic deposition. At the electroanalysis property analysis, it uses the cyclic voltammetry to test the pseudocapacitor behavior on 0.1 M Na2SO4 and specific capacitance.
　　The experiment proves that the electrode of manganese oxides thin films has better specific capacitance under 100℃ and 0.5 minutes by hydrothermal method will getting larger in scanned circles. It reveals that the surface active species of manganese oxides thin films as electrode surface grow by hydrothermal method can not react completely soon on the electrolyte.
