4. What is A PAPER BATTERY?
A paper battery is a flexible, ultra-thin
energy storage and production device
formed by combining carbon nano tubes with a
conventional sheet of cellulose-based paper. A paper
battery acts as both a high-energy battery and super
capacitor . A new energy storage device, that is only
slightly bigger than the size of a stamp and can be
bent and twisted, trimmed with scissors or molded
into any needed shape. More than 90 percent of the
device is made up of cellulose ,about 0.025mm
thick.These are flexible and can be recharged in about
30 seconds
5. HISTORY
The creation of this unique
nano composite paper drew from a
diverse pool of disciplines, requiring
expertise in materials science, energy
storage, and chemistry
It is Created in 2007 by a group of students
at the Rensselaer Polytechnic Institute in
Troy, New York,
6. The continuously advancing technology of portable
electronic devices asks for more flexible batteries to
power them. Here is an ultra-thin and flexible quick
charging battery named ORB, for Organic Radical
Battery, a new energy storage device, that is only
slightly
bigger than the size of a stamp and can be bent and
twisted, trimmed with scissors or molded into any
needed
Shape .

8. Preparation of paper battery
Its easy and effective to prepare paper
batteries
Dip an ordinary piece of paper into ink
infused with carbon nanotubes and silver
nanowires, and it turns into a battery or
supercapacitor.
9. WORKING
Chemical reaction in the paper battery is between
electrolyte and carbon nano tubes.
Electrons collect on the negative terminal of the battery
and flow along a connected wire to the positive terminal,
Batteries produce electrons through a chemical reaction
between electrolyte and metal in the traditional battery.
Electrons must flow from the negative to the positive
terminal for the chemicalreaction to continue. Ionic
liquid, essentially a liquid salt, is used as the battery's
electrolyte. Ionic liquid contains no water, which means
there's nothing in the batteries to freeze or evaporate
therefore allowing the paper energy storage devices to
withstand

11. ESSENTIIAL FEATURES OF PAPER
BATTERIES
Paper batteries
Lighter than metals
Low maintainence
Non toxic and biodegradable
No electrolytic leakages and battery failures
Non fragile
Can be operated at extreme temperatures
Paper battery is extremely flexible as carbon nano tubes are used as the
electrodes.
The paper-like quality of the paper battery along with the nano tubes embedded
in them gives them light-weight and are low-cost.
. The paper battery are also used for medical devices because of their ability to
use electrolytes in the blood.
12. ADVANTAGES OF PAPER BATTERY :
The invention of the paper battery has been hailed as an
efficient "green," or environmentally friendly, technology.
The battery, which is made of up to 90 percent cellulose, is no
thicker than a common sheet of printer paper, about .025 mm
(.00098 inches) thick. Because of its composition, the paper
battery is completely non-toxic and fully biodegradable.
The battery functions as a lithium-ion battery and also as a
super-capacitor. It can provide a long and a steady power
output as compared to the conventional battery.
A paper battery is different from the conventional battery in
the sense that it integrates all the battery components in a
single structure. Paper battery is therefore more energy
efficient.
13. Technical advantages of paper batteries
"They're a one-dimensional structure with very small diameters.“
The small diameter helps the nanomaterial ink stick strongly to
the fibrouspaper, making the battery and supercapacitor very
durable.
The paper supercapacitor may last through 40,000 charge-
discharge cycles – at least an order of magnitude more than
lithium batteries.
The nanomaterials also make ideal conductors because they move
electricity along much more efficiently than ordinary conductors,
14. DURABILITY
Paper battery is extremely flexible as carbon
nanotubes are used as the electrodes. The
sheets can be rolled, twisted, folded and cut
into various shapes with no loss in quality
and efficiency. The components are attached
to each other and the carbon nanotube print
is embedded in the paper and the electrolyte
is soaked in the paper which looks the same
like a paper.
15. Disadvantages of paper batteries
Threats of paper cut
Normal paper is not water proof
Easily flammable
Paper becomes weak over time so it has
a life time limit
Not strong enough for heavy duty work
If recycling includes deinking it creates
effluence
Printing of new paper needs trees to be
cut down
16. Applications of Paper batteries
. The paper battery are also used for medical devices because of their
ability to use electrolytes in the blood
The flexible shape of paper battries will allow it to be used in irregular
electronics
The paper battery could replace the conventional battery
In futre it will be able to supply the power to an implanted pacemaker in
human body by using electrolytes in human blood
The future paper battery will be capable of being made into a super
capacitor or rechargable battery
The paper battery can be operated in extreme temperatures ranging from
-73 to +148 degree celcius
Its low cost of manufacturing finds use in several electronic applications
It can be used in car doors which would power up the components like air
bags etc..
It is easily transpotable and can be twisted or folded
These batteries do not contain caustic chemicals and do not overheat or
explode or produce electrical shock so these can be easily shipped and
stored and disposed after use
As the components are bio degradable paper batteries are eco friendly
17. Paper batteries are used in cosmetis
In preparation on thin displays
18. Conclusion
Through the whole research I come to the
conclusion that paper batteries are cheap and
better source of power generation and are
environment friendly than present lithium ion
battries .paper battries made of silicon are 10
times more powerful than the lithium ion
battries so future power is dependent on paper
battries for a better future
