2. INTRODUCTION
The creation of paper battery drew from a diverse
pool of disciplines, requiring expertise in material
science, energy storage and chemistry.
A paper battery is an electronic battery engineered
to use a spacer formed largely of cellulose. It
incorporates nanoscale structure to act as high
surfaces-area electrodes to improve conductivity.
3. Principle
• The battery produces electricity in the same way
as the conventional lithium-ion batteries, but all
the components have been incorporated into a
lightweight, flexible sheet of paper.
• A conventional Li-ion battery can be incorporated
in cellulose-nanotube composite.

8. Li-ion Battery
Constructed using graphite rod,
lithium cobalt oxide as electrodes and
LiPF6 as electrolyte.
Nominal cell voltage of 3.6-3.7V.
Used in laptop, mobiles, other
consumer electronics.
However it is expensive, delicate, has
high internal resistance and safety
concerns.

10. NICD Battery
Rechargeable battery using nickel
oxide hydroxide and metallic
cadmium as electrodes.
Terminal voltage of 1.2V.
Rugged, high specific power, long
life light.
Used in UPS, portable power tools,
photography equipment, flashlights
and portable electronic devices.
11. Problems with conventional
batteries
Lower specific power compared to fuels.
Weight and size
High charging time
Environmental hazards
Explosion, corrosion, leakage
High cost
Terminal voltage constraints
12. Advantages
Light, rugged, flexible, can be rolled, crunched,
cut, made into any shape.
The nano composite paper is compatible with a
number of electrolyte, like blood, sweat etc..
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.
Non toxic and hence can be used to power
pacemakers and RF tags.
Environment friendly.
13. Limitation
Presently, the devices are only a few
inches across and they have to be scaled
up to sheets of news paper size to make it
commercially viable.
Carbon nano tubes are expensive.
The idea is still in labs and a commercially
viable paper battery will take at least 40-60
years to become a reality.
Researches in nanotechnology to mass
produce nanotubes is promising.
14. Application
Pace makers
Used as alternate to conventional batteries in
gadgets.
Devices in space shuttles
Powered smart cards RF tags, smart clothes.
15. Conclusion
The range of possible applications for paper
batteries derives from their important advantages
as compared to conventional battery technologies.
They can be made in virtually any shape and size
to meet the requirements of each application.
They are rechargeable and have reduced cost and
weight.
However the reality is still very far away, though
the researches are promising.
