3. INTRODUCTION
 A paper battery is a flexible, ultra-thin energy
storage and production device formed by
combining carbon nanotubes with a conventional
sheet of cellulose-based paper.
 It is non toxic, environment friendly and is
everything that a conventional battery is not

4. PAPER BATTERY
 A paper battery acts as both a high energy battery and
super capacitor, combining two components that are
separate in traditional electronics.
 The nano materials are a one-dimensional structure with
very small diameters.
 It can be bent and twisted, trimmed with scissors or molded
into any needed shape
 This technology can be greatly utilized by medical devices

5. PRINCIPLE
 The devices are formed by combining cellulose with
an infusion of aligned carbon nanotubes.
 CNTs exhibit extraordinary strength and
unique electrical properties, and are
efficient thermal conductors.
 A conventional Li-ion battery can be incorporated in
cellulose-nanotube

6. CONSTRUCTION
 Materials required:
a. Copier paper
b. Carbon Nano ink
c. Oven
 Steps involved:
Step 1 - Copier paper is taken.
Step 2 – Carbon nano ink which is black in colour is taken. It
is a solution of nano rods, surface adhesive and ionic
salt solutions. Carbon nano ink is spread on one side of
paper.

7. Step 3 – Paper is kept in the oven at 150C temperature. This
evaporates water content on the paper. The paper and nano
rods get attached with each other.
Step 4 – Place the multi meter on the sides of paper and we
can see voltage drop is generated.
 After drying the paper becomes flexible, light weight
in nature.The paper is scratched and rolled to
protect the nano rods on paper.

8. FABRICATION PROCESS

9. WORKING
 the paper battery integrates all of the battery
components in a single structure
 Paper battery produces electrons due to the
interaction of electrolytes LTO & LCO.
 In paper battery carbon nanotubes acts as cathod
,metal as the anode and paper is seperator.
 Electrons collect on the negative terminal of the
battery and flow along a connected wire to the
positive terminal during discharging

10.  It conducts electricity when paper come into contact
with ionic liquid solution.
 Paper batteries and function between -75C to
1500C.
 Ions flow through thin electrodes quickly , hence
takes very less time to charge.

11. APPLICATIONS
 Smart cards and tags
 Enhanced Printed Circuit Board(PCB)
 Electronic games and entertainment devices
 Medical Sciences: in Pacemakers for the heart, in Artificial
tissues (using Carbon nanotubes)in Cosmetics, Drug-
delivery systems, in Biosensors, such as Glucose meters,
Sugar meters, etc.
Automobiles and Aircrafts:
• in Hybrid Car batteries
• in Long Air Flights reducing Refueling
• for Light weight guided missiles
• for powering electronic devices in Satellite programs

13. ADVANTAGES
 Biodegradable & Non Toxic
 Reusable & Recyclable
 Durable
 Rechargeable
 No Leakage & Overheating
 Very Light Weight & Flexible

14. LIMITATIONS & DISADVANTAGES
 Have Low Shear strength: They can be torn easily.
 The Techniques and the Set-ups used in the
production of Carbon Nanotubes are very
Expensive
 Should not be inhaled, as they can damage lungs.

15. CONCLUSION
Standing at a point in the present where there can’t be a day
without power, Paper Batteries can provide an altogether path-
breaking solution to the same.
Being Biodegradable, Light-weight and Nontoxic, flexible
paper batteries have potential adaptability to power the next
generation of electronics, medical devices and hybrid vehicles,
allowing for radical new designs and medical technologies.
However, commercial applications may be a long way away,
because nanotubes are still relatively expensive to fabricate.
