Abstract-Objective of this paper is synthesis of metal-oxide supported on conducting substrate 
by electrochemical deposition. According to this study analysis of metal oxide thin film were 
done for physico-chemical properties like pH, current density, specific capacitance Vs voltage, 
surface area, cycle stability and coulombic efficiency. In order to get efficient metal-oxide thin 
film for various metal-oxide. Finally, higher energy density materials with better stability in an 
actual operating condition can be obtained by chemical route. 
Key words: - metal-oxide, thin film, chemical route and electrochemical deposition 
 
1. Introduction:- 
The development of electrochemical 
supercapacitors has been attracting a pivotal 
role in micro power source for medical 
instruments, back-up power source for 
computer memories, portable electronic 
systems, digital communication devices and 
electric vehicles due to their high power 
density and long cycle life compared with 
batteries.1-3 Along with that the 
supercapacitors possesses high energy 
density compared to conventional 
capacitors, which leads to greater 
advantages in near future for energy storage 
devices (Figure 1).1-3 To achieve the highest 
power and energy density to have greater 
stable and possessing intrinsic higher energy 
density materials like metal oxides.4 
Viewing to the literature, the metal oxides 
has been synthesized by many chemical and 
thermal treatments, including, chemical 
oxidation, reduction, chemical vapor 
deposition, calcinations, annealing, plus 
laser deposition, and arc discharge, etc.1-4 
Many of these techniques have their own 
advantages like high quality and quantity, 
easy-work up process and mainly have good 
control on size, shape and pore size.1-4,5-7 
However, recently, the Ashvini et al5 has 
reported the synthesis of iron-oxide by 
chemical method, which as shown 
capacitance of ~400 F/g. But, due to the 
metal decoration on carbon substrate is a 
tedious task; it has low stability compared to 
the other reported metal oxide based 
systems.

Figure 1: Simplified Ragone plot of the 
energy storage domains for the various 
electrochemical energy conversion 
systems compared to an internal 
combustion engine and turbines and 
conventional capacitors. 
 In last few decades, researcher are 
focused on the electrochemical deposition 
technique, which possess intimate contact 
between the metal-oxide and support 
substrate, eventually leads to better activity 
and stability during actual operating 
conditions. Looking closely to the literature, 
very recently, Bihag et al4 has reported the 
electrochemical deposition of MnO2 on 
carbon paper by using manganese acetate 
and highlighted the higher electronic and 
ionic mobility within the single system. 
Moreover, the formed nanowall forests have 
given specific capacitance of 1149 F/g with 
better stability in a sodium sulfate solution. 
Therefore, coupling the electronic and ionic 
material could be an elegant solution to 
achieve the desired activity in real 
application devices.  
 Taking the advantage of the recent 
articles, herein we propose the idea to 
generate the active and stable metal-oxide 
based systems by electrochemical deposition 
method, which can be directly grown on the 
conducting substrate, to achieve dual 
characteristic system. This system could 
leads to resolve existing problems related to 
the conductivity and activity of the solar 
system. Therefore, modulating the properties 
of the materials in connection with the 
conducting substrate possessing wide range 
pore size and higher surface area could leads 
efficient charge storage systems for future 
niche applications. 
 
2 Literature Review 
2.1 Literature Review on Metal-Oxide 
Thin Film:- 
Recently, the Kim et al1 has reported 
the synthesis of Mn-Ni oxide films were 
electrodeposited on graphite sheets in a bath 
consisting of Mn-acetate and Ni-Chloride, 
and physico-chemical properties of these 
films were investigated. The electrochemical 
deposited Mn-Ni oxides films were formed 
as nano-fiberous porous structures and 
shown specific capacitance of 424 F/g in 
sodium sulfate (Figure 2).

electrodeposited Mn-Ni oxide electrode in 
0.5 M sodium sulfate.  
 
Bihag et al4 has reported the electrochemical 
deposition method for the Mn-oxide 
nanowall on the carbon fibers of carbon 
papers, using Mn-acetate in a sodium sulfate 
(Figure 3). The formed Mn-oxide nanowalls 
(Mn-CP) have shown specific capacitance of 
~1149 F/g at higher current density of 100 
mA/cm2 (Figure 4).

3. Conclusion: 
Optimization of synthesis of metal-
oxide supported carbon strip to achieve 
better adhesion and thickness with 
controlled surface and porosity by easy 
available metal sources of Fe, Co, Ni, and 
Mn, etc. in an aqueous electrolyte. This 
study mainly deals with real super capacitor 
testing in a two electrode system. The 
deposition and thickness were controlled by 
changing the time of deposition.
