4. INTRODUCTION
 A paper battery acts as both a high energy battery and
super capacitor, combining two components that are
separate in traditional electronics.
 This technology can be greatly utilized by medical
devices.

5. PAPER BATTERY
Apaper battery is a flexible, ultra-
thin energy storage and
productiondevice formed by
combining ‘carbon-nanotube’ with
a conventional sheet of cellulose-
based paper..
•The nano materials are a one-dimensional
structure with very small diameters.
•It is non toxic, environment friendly and is
everything that a conventional battery is not.

6. CONSTRUCTION
CNT thin films were coated onto stainless steel substrates with a
solution based process
The concentration of CNT is 1.7mg/ml
Add film with a thickness of 2 micrometer was formed after drying
the CNT ink on the SS substrate at 80°C for 5 min. this film is then
peeled off from substrate.
These films as electrodes of paper battery.
One films is pasted to electrolyte LTO(lithium titanium oxide) and
the other film is pasted to electrolyte LCO(lithium cobalt oxide).
Paper is sandwiched between two electrolytes LTO and LCO with
PVDF (Poly vinili dine fluoride) acting as glue.

10. WORKING
 Internal operation of paper batteries is similar to that of
conventional batteries with each battery generating about
1.5V.
 If one can recall traditional batteries work in the manner
where positive charged particles called ions and negative
charged particles called electrons move between positive
electrodes called anode and negative electrode called
cathode. Current flows as electrons flow from anode to
the cathode through the conductor, since the electrolyte
is an insulator and doesn’t provide a free path for
electrons to travel.

11. WORKING….

12. WORKING
 Similarly in some paper batteries, carbon nanotubes act
as cathode, the metal is the anode and paper is the
separator.
 Chemical reaction between metal and electrolyte results
in production of ions whereas chemical reaction between
carbon and electrolyte results in production of electrons.
These electrons flow from the cathode to the anode
through the external circuit.

13. APPLICATIONS

14. APPLICATIONS
 Wearable Computers – One of the latest real time
examples of wearable computers is Google Glass. It
actually is a normal spectacle with an optical head
mounted display and Glass is a computer in the form of
a pair of eyeglasses and includes an optical head-
mounted display which allows the user to use a smart
phone.
 It can be used for low power devices like calculators,
wrist watches and wireless communication devices like
mouse, Bluetooth headphones, keypads etc.

15. ADVANTAGES
 Paper battery function as a battery as well as a
capacitor.
 Paper battery is a modern storage device with ultra-
thin in size.
 Paper battery can generate electrical energy of 1.5V.
 Unlike the conventional battery , Paper battery can
be used by folding , cutting and rolling.
 It has special properties such as more economical,
biodegradable and Bio-compatible.
 The output voltage of this battery can be customized
based on requirement.

16. LIMITATIONS
The carbon nano-tubes used in this battery
are very expensive.
The paper battery wastage may damage lungs
if it inhaled.
The e-wastage is generated by paper
batteries.

17. FUTURE SCOPE
 It holds great potential to advance capabilities in portable
power design for applications ranging from
bioinstrumentation to consumer electronics and even
large power systems served by conventional batteries.
 The paper like qualities of the material make it especially
attractive for energy storage in medically implanted
devices (for example, a pacemaker, insulin pump or the
implantable radio chip).

18. CONCLUSION
 A paper battery is a paper like device formed by the
combination of carbon nanotubes and a conventional
sheet of cellulose-based paper which act as a flexible
ultra-thin energy storage and energy production device.
 As this technology is adapted it will prove to be
extremely useful and could even save not only cost but
lives also.
