由於電化學超級電容繼承了電池和電容的混合特性，目前正在為電子和汽車應用開發電化學超級電容。 電化學電容具有比電池更好的功率密度和比電容更好的能量密度，以及更長的迴圈壽命和快速充放電，使其成為各種應用的理想選擇。 二氧化錳具有成本低、理論電容量大、環境友好等優點，是一種理想的電化學電容電極材料。 然而，它的低電子和離子電導率阻礙了其在實際應用中的應用。 另一方面，聚吡咯具有更好的導電性，但理論電容較低。 因此，需要進一步研究以提高上述超級電容器電極的實際應用效能。
本論文採用恆流電化學沉積科技，將金屬氧化物和導電聚合物製成超級電容電極。這項工作分為兩個部分：第一部分，採用恆電流為5 mA/cm2的電化學沉積工藝，在兩個不同的電極（陽極和陰極）上同時合成了MnOx和聚吡咯。 利用掃描電鏡、X射線能譜、X射線衍射和傅立葉變換紅外光譜分別對所製備電極的形貌、元素組成、結構和官能基進行研究。
迴圈伏安計、恆電流充放電和電化學阻抗譜也用於評估電極的電化學效能。 出於各種目的，這些合成過程可用於製備二元和三元奈米複合電極。 在第二部分中，我們使用反向電沉積方法製備了用於電化學電容器的奈米複合電極。 用MnOx-NS表徵了用倒置沉積科技合成的以硝酸錳和吡咯單體為前驅物的奈米複合電極/ PPy@t 式中，t表示沉積時間。 這種奈米複合電極表現出良好的偽電容行為，其比電容幾乎是MnOx-NS的三倍

Because of their hybrid features inherited from batteries and capacitors, electrochemical supercapacitors are now being developed for electronics and automotive applications. Electrochemical capacitors have better: power density than batteries and energy densities than capacitors, as well as long cyclic life and quick charge-discharge, making them ideal for a variety of applications. Manganese dioxide is a desirable electrochemical capacitor electrode material contender because of its low cost, high theoretical capacitance, and environmentally friendly. However, it’s low electronic and ionic conductivities have hampered its use in practical applications. On the other hand, polypyrrole have better electrical conductivity but lower theoretical capacitance. Therefore, further investigations are required to improve the performance of those aforementioned supercapacitors electrode for practical application.
In this thesis, an electrochemical synthesis technique known as Galvanostatic electrochemical deposition was used to make supercapacitors electrodes out of metallic Oxide and conducting polymer. This work is divided into two sections: In the first section, using an electrochemical deposition process with a constant current of 5 mA/cm2, MnOx and polypyrrole were synthesized at the same time on two different electrodes known as anode and cathode. Scanning electron microscopy, X-ray spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy were used to examine the morphology, elemental composition, structure, and functional group of the prepared electrodes respectively.
A cyclic voltammeter, galvanostatic charge-discharge, and electrochemical impedance spectroscopy were also used to assess the electrodes' electrochemical performance. For various purposes, these synthesis processes can be employed to prepare binary and ternary nanocomposite electrodes. In the second section, we prepared nanocomposite electrodes for electrochemical capacitors using the inversion electrodeposition approach. The synthesized nanocomposite electrode form manganese nitrate and pyrrole monomer precursor by inversion deposition technique is assigned by MnOx-NS/PPy@t where t stands for the deposition time. This nanocomposite electrode exhibits a good psudocapacitive behavior with almost three times as high as the specific capacitance of MnOx-NS
