Role of sulfuric acid
in these batteries
Sulfuric acid plays a fundamental role in the operation of lead-acid
batteries, with its primary purpose being to serve as an electrolyte. An
electrolyte is a medium that allows the flow of electrical charge
between the battery plates. In the charged state, the battery contains a
diluted concentration of sulfuric acid and lead dioxide; when the
battery discharges, the sulfuric acid reacts with lead dioxide to
produce electricity, creating lead sulfate and water in the process.
The presence of sulfuric acid within a lead-acid battery is crucial
because, during the discharge process, the lead active material is
transformed into lead sulfate by acid from the electrolyte. This process
is reversed during charging, where lead sulfate and water are
transformed back into lead and sulfuric acid. This cycle can be repeated
many times; however, over time, some lead sulfate does not convert back
into lead and sulfuric acid, thus leading to the gradual weakening of
the battery over time.
The sulfuric acid concentration in the electrolyte also acts as an
indicator of the battery’s charge state. A higher concentration
signifies a higher state of charge. This property is used by some
battery chargers to accurately determine when to stop the charging
process. In conclusion, sulfuric acid not only facilitates power
generation in lead-acid batteries but also plays an essential role in
the battery’s overall lifecycle and functionality.

electrolyte in these types of batteries. Simply put, it is the medium
that allows for the movement of ions between the nickel and cadmium
plates inside the battery, a process which is crucial for the production
of electricity.
In a fully charged nickel-cadmium battery, the negative plates
contain cadmium hydroxide while the positive plates contain nickel
hydroxide. When the battery is discharged, both the cadmium and nickel
plates react with the potassium hydroxide electrolyte. This reaction
produces water along with other compounds, and it also generates
electrons, which then produce an electric current.
Consequently, the presence and maintenance of potassium hydroxide in
these batteries are essential for their efficient function. It’s a key
player in the chemical reactions that generate the battery’s power. It’s
important to note that while it facilitates the energy production
process, potassium hydroxide is not actually consumed in the reactions.
Therefore, it remains in the battery for its lifespan, continually
enabling the energy generating reactions.
Other types of
battery acids and their functions
Beyond sulfuric acid and potassium hydroxide, there are several other
types of battery acid utilized in different types of batteries, each
serving its own unique function. Lithium-ion batteries, for example,
often employed in smartphones, laptops, and electric cars, use a lithium
salt in an organic solvent as the electrolyte. The high energy density
and rechargeability of lithium-ion batteries can be attributed to the
reaction of this acid.
Alkaline batteries, frequently found in remote controls and toys, use
a potassium hydroxide solution as the electrolyte. It allows the flow of
ions, which is essential for the battery to provide electricity.
Zinc-carbon batteries, typically utilized in low-drain electronic
devices like wall clocks and radios, use a combination of ammonium
chloride and zinc chloride as the electrolyte. This acidic solution aids
in conducting electricity by moving ions between the zinc and carbon in
the battery.
Nickel-metal hydride batteries, an improvement over nickel-cadmium
batteries, use a potassium hydroxide solution as the primary
electrolyte. These batteries are commonly found in hybrid cars, due to
their ability to be recharged many times and their minimal impact on the
environment in comparison to other batteries.
The role of the aforementioned battery acids is indispensable, as
they facilitate the movement of ions from one electrode to another,
