A paper battery is a flexible, ultra-thin energy storage device formed by combining carbon nanotubes with conventional paper. It acts as both a high-energy battery and supercapacitor. Paper batteries are eco-friendly, flexible, lightweight, and store much power in less space. They are constructed using a cellulose-based paper separator with carbon nanotube cathode and lithium anode layers. Paper batteries generate electricity through ion flow between the electrodes during charging and discharging. Their flexible design has applications in electronics, medical devices, and vehicles. While expensive to produce currently, paper batteries may replace conventional batteries in the future due to their safety and design advantages.

4. What is
paper battery?
02
A paper battery is flexible , ultra thin
energy storage and production
devices formed by combining
carbon nanotube with a
conventional sheet of cellulose
based paper
A paper battery acts as a both high
energy battery and super capacitor.

5. FEATURES OF PAPER BATTERY
FLEXIBLE STRUCTURE
CAN BE BENT IN ANY DIMENSION
NON TOXIC
ECO FRIENDLY
PROVIDE BOTH LONG TERM , STEADY POWER PRODUCTION AND
BURST OF ENERGY
ULTRA THIN IN SIZE
LESS SPACE

6. WHY TO USE PAPER
BATTERY
1) ELECTROCHEMICAL BATTERIES
limited life , leakage , environmental
concerns .
2) SOLAR CELLS
Versatality , portability and size , need an
auxiliary back up battery
3) FUEL CELLS
Cost , Portabiity & size
Disadvantages of other batteries

7. CONSTRUCTION
The major components used for the
construction of paper battery include:
Carbon Nanotube (CNT) used for cathode
terminal
Lithium metal (Li+) used for anode terminal
Paper (Cellulose-Separator)

8. CONSTRUCTION
Step 1: Take a cellulose-based paper and
apply black carbon ink on it
Step2: Spread this ink applied on the paper
Step3: After spreading ink, laminate a thin film
over the cellulose surface
Step4: Heat the cellulose paper for 5min at 80
degrees C
Step5: Then, peel off the film from the
substrate
Step6: The electrodes of paper battery are
formed by film. The electrolytes LTO and LCO
are connected to different films
Step7: The functioning of paper
battery can be checked by
connecting battery terminals to the LED

10. In simple
words :-
Paper Battery= Paper (Cellulose) + Carbon Nanotubes

11. Working of PAPER BATTERY
. The Paper battery works when the paper is
dipped in the ion-based liquid solution; next
a chemical reaction occurs between the
electrodes and liquid.
The electrons move from the cathode to
anode to generate electricity.
The paper electrode stores energy while
recharging within 10 seconds because the
ions flow through the thin electrode quickly.
The best method to increase the output of
the battery is to stack different paper
batteries one over the other.

12. ADVANTAGES OF PAPER
BATTERY
•A paper battery can work even if it is folded, cut or rolled up.
•A Paper battery consists mainly of carbon and paper; it can be used
to power pacemakers within the body.
•A paper battery can be used both as a capacitor and battery.
•It is an ultra-thin storage device.
•It is biodegradable, nontoxic, bio-compatible and economical.
•It generates close to 1.5V of energy.
•It is durable, easily recyclable and reusable.
•It is Overheating and Leakage proof.
•Flexible and Very Light Weight
•Easily Moldable Into different sizes and shapes
•Output voltage is customizable due to the fact that CNT (carbon
nanotubes) concentration can be varied and stacking/slicing can be
changed

13. DISADVANTAGES OF PAPER
BATTERY
• This type of batteries can be torn easily
as they have low shear strength.
• The methods (e.g. arc discharge, CVD,
ablation, electrolysis) used in carbon
nanotubes manufacturing are expensive
and less efficient.
• They are harmful to human being when
inhaled
• Nanotubes made from carbon are
expensive due to use of procedures like
electrolysis and laser ablation.

14. APPLICATIONS
• It can be used in electronics for charging various devices
e.g. laptop, cameras, mobile phones, calculators etc.
• It can be used in wireless devices e.g. mouse, keyboard,
speakers, bluetooth headsets etc.
• It can be used in medical applications such as artificial
tissues, cosmetics, glucose meters, sugar meters etc.
• It can be used in aircrafts and automobiles as hybrid car
batteries, guided missiles etc.
• E-cards , greetings , talking posters
• Power smart cards RF id tags , Microprocessors

15. FUTURE
SCOPE
After studying the problems associated
with the most commonly used batteries
we can conclude that paper batteries
along some modifications like Li-ion +
CNT paper or some other possible
combinations can replace the
commonly used batteries. And making
them much safer, flexible and light weight
GROWING DEMAND FOR THINNER
AND SMALLER ELECTRONIC
DEVICES , PAPER BATTERIES CAN
PLAY AN IMPORTANT ROLE IN THE
FUTURE

16. CONCLUSION
Being Biodegradable, Light-weight and
Nontoxic, flexible paper batteries have
to power the next
generation of future electronics,
medical devices and hybrid vehicles,
allowing for radical new designs and
mainly medical technologies
