This type of battery comprises three main components: an
anode, a cathode and an electrolyte. The discharging battery
serves as a galvanic cell that drives the electrical current in
an external circuit. The electrolyte plays an important role in
such a battery because it is the conducting medium through
which the two-way charge transfer proceeds between the
electrodes [18]. The electrolyte also separates the anode and
the cathode to avoid a short circuit and simultaneously provides
hydroxide ions to maintain the electrochemical reactions
