本論文研究主要為延續實驗室先前於ITO上造出鎳多孔材技術之應用。希望可以於金屬基材上作出同樣多孔材結構，並希望可以增加其表面積來達成具有高表面積材料，最後應用於鈷電容研究。
於鎳基材上欲增加表面積有二種方式，一種方式是將孔洞變大，另一種是將鍍層厚度增加。利用不同電位析出，電位高孔洞小。而增加鍍液中銅濃度(CuSO4)至0.2M可以發現孔洞變大。但是析出電量會增加鍍層厚度，所增加表面積最多。
因此增加析出電量方式，由一庫倫增加至三庫倫，可原來厚度1μm增加至3~5μm，且孔洞也變大一些。當造出具有高表面積之多孔材，接著就進行陽極沈積法沈積鈷氧化物。
我們運用陽極沈積法於0.1M醋酸鈷溶液中沉積Co2O3於鎳多孔材上，Co2O3以薄薄一層覆蓋於鎳多孔材基材上，以循環伏安法測試其電容性值可看出具有良好電容可逆性之電流曲線，顯示電極有理想的擬電容特性與電化學可逆性，且電容值高達911F/g以上。再以循環伏安法進行充放電測試可發現電容值持續增加，當達2000cycle時電容值約增加2.38倍，即電容值高達2167F/g，且增加後還是具有良好電容可逆性。

This study illustrates the application of porous material from Ni electrode. We prepare large surface area porous material by increasing the surface area and implement cobalt super-capacitors investigation.
There are two kinds of methods may increase the surface from Nickel substrate. One is the increase of the pore size, and the other is the addition of deposition thickness. Electrodeposition at various potentials, the pore size is small while the potential is high. However, the pore size becomes larger while increases the copper concentration (in CuSO4) to 0.2 M. When the electrodeposition implements at three coulombs, most of the pores begin to peel off from the substrate material, it can be attribute to the larger concentrations of copper ions cause larger percentage for copper electrodeposition. Moreover, with the addition of charge from 1 to 3 comes higher than that obtained from 2ulomb, the deposition thickness changes from 1μΜ to 3 ~ 5μΜ, and the pore size becomes larger. As for larger surface porous material, we use anode deposition to electrodeposite cobalt oxide.
We implement Co2O3 deposition by using 0.1 M cobalt acetate solution, the Co2O3 thin films cover on the surface of nickel porous material. Cyclic voltammetry experiments show that the capacitance available from the porous Ni electrode is 911F/g, which is 2.38 ti000 cycles
