Batteries
are electrochemical systems that convert chemical energy into electrical
energy. While electrical energy is generated by oxidation of the at the anode
in these systems, in which anode and cathode parts are separated with a
membrane, reduction reaction occurs at the cathode. Hydrogen sulfide (H₂S)
acts as a fuel because of the contained S⁼ ions and electricity
generation is provided while S⁼ ions are transforming into S⁰ with
the following reaction via the oxidation reaction at the anode: S⁼ →
S⁰ + 2e⁼

Meanwhile, MS
(metal sulfides) formed on the surface increases the battery's activity. Thus,
an unwanted and pollution constructive chemical substance is not released to
the atmosphere so environmental pollution is prevented; electrical energy is
generated as well as a cell, whose activity increases while working, is
developed.

Hydrogen sulfide
is a harmful gas but its emergence is inevitable as a result of many energy
production processes. Some processes allow the cleaning of the fuels prior to
combustion, while some processes are being implemented to keep H₂S
in the flue gas formed as a result of combustion without releasing to the
atmosphere.

In this study, Cyclic Voltammetry
Technique is used for the electrochemical measurements. Cyclic voltammetry is
an electrochemical method widely used in clarifying the structure of the
electrochemical reactions. Cyclic voltammetry is one of the simplest and most
powerful electrochemical techniques utilized in determining thermodynamics of
oxidation-reduction reactions, electrochemical reactions and chemical reaction
mechanisms marching together with electrochemical reactions. In cyclic
voltammetry studies, the potential is scanned in forward and backward at a
constant speed in a certain range. Findings and achievements obtained as the
results of this study can be grouped as follows:

·        
It
was observed that electrical energy could be obtained from solutions containing
sulfur by using the battery system.

·        
Thus,
an environmentally friendly battery is prepared.

·        
Its
activation is increased with the usage of the electrode surface.

·        
It
was observed that the prepared battery is cheap.
