Paper batteries provide a flexible, lightweight alternative to conventional batteries. They are constructed by combining carbon nanotubes with cellulose-based paper to form electrodes. During use, an oxidation reaction occurs at the anode while a reduction reaction occurs at the cathode, generating a flow of electrons. Paper batteries have advantages over conventional batteries like being bendable, biodegradable, and able to charge within 10 seconds. However, they also have disadvantages such as higher cost and challenges related to scaling up. Potential applications include use in electronics like watches, calculators, and laptops.

PAPER BATTERY

2. CONTENTS
• What is Paper Battery
• Construction
• Working
• Comparison
• Advantages
• Disadvantages
• Applications
• Conclusion

3. Paper Battery
• A conventional battery takes up a huge amount of
space and contributes to a large part of the device
weight
• Paper battery is flexible and ultra thin energy
storage device .
• It act as both high energy battery and super
capacitor. This combination allows the battery to
provide both long term, steady power production
of energy
• It can be rolled , twisted or folded

4. Anatomy of paper battery is based on
the use of carbon Nano tubes tiny
cylinders to collect electric charge
Paper as a medium is the well
designed structure of millions of
interconnected fibers in it. These
fibers can hold on Nano tubes easily
Paper batteries will replace
conventional batteries and Li-ion
batteries

5. Construction
Paper Battery

6. • Formed by combining carbon nano tubes with a
conventional sheet of cellulose- based paper
• Nano tubes acts as electrodes, allowing the storage
device to conduct electricity
• Paper battery integrates all of the battery
components in single structure,
makes it more energy efficient
• Carbon nano tubes exhibit extra
ordinary strength and unique
electrical properties

7. Black carbon ink is applied on cellulose paper

8. Spread the carbon ink on cellulose paper

9. Then it is heated in a oven at 150 degree centigrade

10. Terminals are attached to the paper

11. Probes are connected to a LED

12. Paper as a medium is the well designed structure of millions
of interconnected fibers in it. These fibers can hold on Nano

13. CARBON NANO TUBES
• A Carbon nano tubes is a tube shaped material made
of carbon, having a diameter measuring on the
nanometre scale
• It typically have diameter ranging from <1nm up to
50nm
• The graphite layer appears like a continuous unbroken
hexagonal mesh& carbon molecules at the apex of the
hexagons
• The CNT have many structures, the electrical
characteristic differ depending on these variations
• They are the stiffest and strongest fibre known

15. Fabrication process of CARBON NANO TUBES

16. WORKING
Cathode : carbon nano tube (CNT)
Anode : lithium
Electrolyte : Bio electrolyte
Separator : paper

17. • Anode and cathode are electrodes in the battery and
they are in contact with electrolyte
• When an external load is connected to the battery ,
the circuit is closed
• Then current begins to flow because of electro
chemical reaction occurs inside battery
• Oxidation take place at anode
• Reduction takes place at cathode
• Anode losses electrons to the electrolyte. And it is
said to be positively charged
• Cathode gains electron from the electrolyte. Hence it
is negatively charged

19. Conventional battery Vs paper battery
• Chemical reaction
between electrolyte &
metal
• Class 9 miscellaneous
hazardous material
• Takes time for charging
• Cost is less
• Chemical reaction
between electrolyte &
carbon nano tube
• Bio degradable & non
toxic
• It can store charge while
recharging in 10 seconds
• Cost is high

20. Flat discharge curve
Typical discharge curve for the paper battery compared to a
commercially available metal casing cell with similar chemistry. Both
cells were discharged under typical operation load

21. Advantages of paper battery
• It can be rolled, twisted, folded in to numerous shape
• No loss of integrity
• Light weight
• bio degradable
• Non toxic
• It can be a super capacitor

22. Disadvantages
• Carbon nano tubes are very expensive
• For the commercial purposes , these batteries
have to be scaled up to sheet sheets of news
paper size
• Replacing the old batteries w results
wastage of old electronic goods

23. Application
• Alternate to conventional batteries
• Pacemakers in heart (uses blood as electrolyte)
• calculators, wrist watches and other low drain
devices
• Laptop , mobile and other electronic gadgets
• Wireless communication devices like keyboard ,
mouse and Bluetooth headsets
• E-cards
• Talking poster

24. Conclusion
• The life of battery is an important parameter
which decides the area of application of battery
• This Paper Battery can further reduce the weight
of electronic gadget
• the future may allow simply painting the nano
tube ink and active materials on to surface such as
walls
• High storage of energy leads to decrease charging
time . Thus energy can be saved
