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
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

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
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
