2. A battery is an electrical device which is used to
alter the chemical energy to electrical energy.
Batteries are classified into different types
based on the application, and these are used in
several electrical as well as electronic devices.
An electrical battery includes certain chemicals
like compounds of mercury, lead etc and the lead
of a battery is extremely dangerous in nature
and are not environment-friendly.
3. Apart from these, there is a chance for chemical
leakage as well as the explosion of the battery
in certain cases. To overcome this problem
researchers have invented Bio-battery which
reduced the impact of these chemicals and
reduces the harm to the environment which
gives a great advantage to humans.
4. What is Bio-Battery?
A Bio battery is an electrical energy storage
device which is used in several applications.
This battery can be powered with the help of
organic compounds that are available in glucose
form that is used in the human bodies.
In the human body digestion procedure, as
enzymes break-down the glucose electrons, as
well as protons, are released. Thus by utilizing
enzymes for break-down glucose, these
batteries will get energy from glucose directly.
Then these batteries will store the energy for
the future purpose.

6. This idea is approximately identical to how both
plants and animals get energy. Even though
these batteries still are being checked before
being sold. There are many researchers as well
as engineers are working for the future
development of these batteries.
7. Bio-Battery Construction
The bio-battery construction can be done by
using four components such as anode, cathode,
electrolyte, and separator.
All these four components are coated on each
other. Similar to other batteries, in these
batteries, the anode is negatively charged as
well as the cathode is charged positively. In
bio- battery construction, the anode terminal is
placed at the top of the battery whereas the
cathode terminal is placed at the bottom of the
battery. In between these two terminals
electrolyte is placed which includes a separator.

9. Here, separator plays a key role by separating the
anode and the cathode terminals from one
another which can be lead to avoid the short
circuit otherwise the entire battery will
damage. In this system, the electricity will be
generated by the flow of electrons as well as
protons. Because the main energy source of
Bio-battery is glucose so it requires plenty of
glucose for generating the electricity. In the
bio-battery, the breakdown of glucose can be
done on the same rule while it is broken down
into small pieces in the body of humans.
10. Bio-Battery Working Principle
This system uses the flow of electrons as well
as protons for generating electricity. The
proton movement can be occurred due to the
moving force which is known as current. The
electrons flow can be from anode to cathode
whereas current flow can be from cathode to
anode. The bio-battery working operation is
discussed below.
11. In the above figure, glucose is used at the
anode side whereas enzyme is used at the
cathode side
Glucose gets broken down into electrons and
protons
The flow of protons can be travel to cathode
side via a separator and the flow electrons can
be travel to cathode side via a mediator.
Finally, electric energy will be generated.
12. Types of Bio-Batteries
Enzymatic Bio-Battery, Microbial Bio-Battery
are the commonly used batteries.
1) Enzymatic Bio-Battery: In this type of
battery, biochemical agents (Enzymes) are
utilized for a breakdown of a substrate.
13. 2) Microbial Bio-Battery: In this type of
battery, Microorganisms such as Escherichia
coli, are utilized for a breakdown of a
substrate.
14. Advantages of Bio-battery
1-Biobatteries are much faster in charging the
devices because of the quick action of the enzymes
when we compared to other batteries.
2-Bio-batteries don’t require external power
supply due to the constant supply of glucose or
sugar.
3-Bio-batteries available by a high-energy density
and it can be used easily at room temperature.
4-Biobatteries are totally non-polluting, renewable,
and also environmentally friendly.
5-Biobatteries are very secure to use due to no
leakage and explosions like chemical batteries.
15. Disadvantages of Bio-battery
1-The bio-batteries preserve less amount of
energy as compared to lithium-based electrical
batteries.
2-These batteries cannot be used for the long-
term as well as storage.
16. Applications of Bio-battery
1-Bio-batteries are used in medical implants like
pacemakers, insulin pumps, etc.
2-It can be used as a charger for electronic
devices like cell phones, tabs, power banks, etc.
3-Bio-batteries can be used for toys as well as on
the greeting cards.
4-Bio-batteries are used in the defense field in the
remote sensing devices, spying and monitoring
devices.
