3. INTRODUCTION
A Bio-battery is an energy storage device that is
powered by organic compounds usually being
glucose such as glucose in human blood.
 Bio-Battery generates electricity from renewable fuels (glucose,
sucrose, fructose, etc ) providing a sustained, on-demand
portable power source.
 When enzymes in our bodies break down glucose, several electrons
and protons are released.
 Therefore, by using enzymes to breakdown glucose, bio-batteries
directly receive energy from glucose.
 These electrical energy stored batteries are used later as required.

4. NEED OF BIO BATTERY
 An electricity shortage is felt most by those who depend on electricity
for heating, cooking, and water supply.
 In these circumstances, a sustained energy crisis may become
a humanitarian crisis.
 As it is known that the energy conservation is the major issue these
times so the bio-battery is one of the energy conservation method and
it is a renewable energy source.
 It can save a lot of power and it is also energy efficient phenomenon.
 Its energy density, size , weight, instant recharge, flexible shape,
renewable biocatalyst , room temperature operation and readily
available fuel created the necessity of these batteries.

5. CONSTRUCTION OF BIO BATTERY
 Bio-batteries contains:
an anode, cathode, separator and electrolyte, which are the
basic components to any cell battery.
 Anodes and cathodes are the negative and positive areas on a
battery.
 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.
 Between the anode and the cathode lies the electrolyte which
contains a separator.
 The main function of the separator is to keep the cathode and
anode separated, to avoid electrical short circuits.
 This system as a whole, allows for a flow of protons (H+) and
electrons (e-) which ultimately generate electricity.

6. HOW IT WORKS
 Glucose is broken down on the anode side
of the battery, producing protons (H+) and
electrons (e-).
Glucose→Gluconolactone+2H+ + 2e−
 The protons (H+) are transferred to the
cathode side through the separator, while
the electrons (e-) are transported to the
cathode side through the mediator, which
transfers them to the external circuit.
 The cathode uses the enzymes to drive an
oxygen-reduction reaction which ultimately
produces water using both the protons
(H+) and the electrons (e-) transferred from
the anode.
O2 +4H+ +4e− →2H2O.
 These reactions at the anode and cathode
generate electric energy by creating proton
(H+) and electron (e-) flow in the cell
system.

8. TYPES OF BIO BATTERY
There are mainly TWO types of Bio-Batteries.
 Enzymatic Bio-Battery: In this type of battery,
biochemical agents (Enzymes) are utilized for a
breakdown of a substrate.
 Microbial Bio-Battery: In this type of battery,
Microorganisms such as Escherichia coli,
electric bacteria, are utilized for a breakdown of
a substrate.

9. TEMPERATURE STABILITY
 Plot of maximum current (at
10-ohms) versus time for Bio

storage conditions.
 Shows repeatable, reliable
performance and stable
operation from -30°C to
+55°C for more than 6
months.

10. ADVANTAGES
 Faster in charging the devices because of the quick action of
the enzymes
 Totally non-polluting, renewable, and also environmentally
friendly.
 Raw materials available easily & plenty
 Portable & light weight compared to fuel cell.
 Readily available fuel source.
 Very secure to use due to no leakage and explosions like
chemical batteries
 Non-flammable and non-toxic fuel is used. 10

11. DISADVANTAGES
 Compared to conventional batteries, such as lithium
batteries, bio-batteries are less likely to retain most of
their energy.
 This causes a problem when it comes to long term usage
and storage of energy for these batteries.

14. CONCLUSION
 Bio batteries are High performing, stable.
 Even so, Bio battery the small, flexible, long lasting and
environmentally friendly battery technologies discussed
here show the great possibilities researchers see in bio-
batteries, especially for the field of medicine.
 This causes a problem when it comes to long term usage
and storage of energy for these batteries. However,
researchers are continuing to develop the battery in order
to make it a more practical replacement for current
batteries and sources of energy.
