2.  A paper battery is a flexible, ultra-thin energy storage and
production device formed by combining carbon nanotube with
a conventional sheet of cellulose-based paper.
 A paper battery acts as both a high-energy battery and super-
capacitor.
WHAT IS A PAPER BATTERY?

3. CONVENTIONAL
BATTERY Vs PAPER
BATTERY
 Generally Li-ion re-chargeable batteries are used in
mobiles,laptops and most of the electronic devices.
 Conventional battery produce electrons through a
chemical reaction between electrolyte and Metal.
 Whereas, Chemical reaction in Paper battery is
between electrolyte and carbon nanotubes.
.

4. Disadvantages of
Conventional batteries
• EXPENSIVE -- 40% more than NiCd.
DELICATE -- battery temperature must be
monitored from within, and sealed
particularly well.
REGULATIONS -- when shipping Li-Ion
batteries in bulk (which also raises the
price).
Class 9 miscellaneous hazardous material

5. MATERIALS AND DESCRIPTION
 This energy stored device is based on two
Basic,Inexpensive materials.
 CARBON NANOTUBES
 CELLULOSE(Because of its composition and
structural features, the paper battery is not harmful
and it is fully recyclable)
 Also an ionic liquid provides
the third component:
 ELECTROLYTE

6. WHAT IS A CARBON NANOTUBE
 Carbon nanotubes(CNTs) are allotropes of carbon
with a cylindrical nanostructure.
 A carbon nano tube is a tube-shaped material, The
diameter of a nano tube is in the order of a few
nanometers.
 Carbon nano tube have many structures differing in
length, thickness and in type of helicity and number of
layers.
 Their electrical characteristics differ depending on
these variations, either acting as metals or as
semiconductor.

14. HOW PAPER BATTERY WORKS
 While a conventional battery contains a number of
separate components, In paper battery all of the
battery components are in a single structure, making it
more energy efficient, integrated device.
 . The paper battery contains carbon nano tubes, which
acts as electrode. The nano tubes are embedded in a
sheet of paper soaked in ionic liquid electrolytes,
which conduct the electricity.

15. WORKING
 Batteries produce electron through a chemical reaction
between electrolyte and metal in the traditional
battery.
 Chemical reaction in the paper battery is between
electrolyte and carbon nano tube
 Electrons collect on the negative terminal of the
battery and flow along a connected wire to the
positive terminal.
 Electrons must flow from the negative to positive
terminal for the chemical reaction to continue.

16. STRUCTURE OF PAPER BATTERY

17. FEW IMPORTANT REASONS HOW PAPER
BATTERIES ARE BETTER THAN THEIR
CONVENTIONAL COUNTERPARTS
 Paper batteries have long lasting time
 They are non-toxic as they do not involve harmful
chemical reactions.
 They are disposable as they are made up of cellulose
which is Bi o-degradable and non-toxic
 They can be used in harsh climate conditions like
extreme heat(150) and extreme cold (-75) because
electrolyte doesn't involve water.

18.  The flexible battery can function even if it is rolled up,
folded or cut.
 We can get 2.5 volts of electricity from a sample
the size of a postage stamp.
 "If we stack 500 sheets together in a ream, that's 500
times the voltage. If we rip the paper in half we cut
power by 50%. So we can control the power and
voltage issue."
 Because the battery consists mainly of paper and
carbon, it could be used to power pacemakers within
the body where conventional batteries pose a toxic
threat.

20. PAPER BATTERY OFFERS FUTURE
POWER
The black piece of paper can power a small light.
 Flexible paper batteries could meet the energy demands of
the next generation of gadgets.
The ambition is to produce reams of paper that could one day
power a car.
The paper battery was a glimpse into the future of power
storage.

21. CONCLUSION
 These paper batteries can reduce the weight of the
electronic gadgets.
 This energy storage device can be used in the smallest
and most diversely designed electronics such as cell
phones,Mp3 players and medical equipment.
 The use of Ionic liquid makes the device
environmental friendly; A major concern in NANO
technology.
