3. Slide 2: Introduction to Paper
Batteries
1)A paper battery is a flexible, ultra-thin energy storage and
production device formed by combining carbon nanotube with
a conventional sheet of cellulose-based paper.
2)A paper battery acts as both a high-energy battery and super-
capacitor , combining two components that are separate in
traditional electronics .
4. Slide 3: Contant
WHY TO USE PAPER BATTERY?
1) Ultra-thin size & flexible structure.
2) Exhibits property of super-capacitor(22F-36F per gram)
3)Operating temper ature(-75 to 100 degree celsius)
4) provide both long-term, steady power production andbursts of
energy.
5)Cost-effective.
5. Slide 4: Advantages of Paper Batteries
• Lightweight and flexible nature
• Environmental benefits (biodegradable, reduced e-waste)
• Potential for integration into wearable devices and IoT
• The flexible battery can function even if it is rolled
up, folded or cut.
•We can get 2.5 volts of electricity from a sample the
size of a postage stamp.
6. Slide 5:Disadvantages
• EXPENSIVE -- 40% more than NiCd.
• DELICATE -- battery temp must be
monitored from within (which raises the
price), and sealed particularly well.
• REGULATIONS -- when shipping Li-Ion
batteries in bulk (which also raises the
price).
Class 9 miscellaneous hazardous material
7. Slide 6: Types of Paper Batteries
• Single-cell paper batteries
• Foldable and stackable configurations
• Integration with other energy storage systems
8. Slide 7: Applications of Paper
Batteries
• Portable electronics (smartphones, tablets)
• Medical devices (implantable sensors, drug delivery)
• Smart packaging and labels
• Environmental monitoring
9. Slide 8: Working
1.While a conventional battery contains a number of separate components,
the paper battery integrates all of the battery components in a single
struc 2.Traditional Batteries produce electrons through a chemical reaction
between
electrolyte and metal.
3.paper battery produces electrons due to the interaction of electrolytes LTO &
LCO.
4. Electrons collect on the negative terminal of the battery and flow along a
connected wire to the positive terminal during discharging.
5. Electrons must flow from the negative to the positive terminal for the ture,
making it more energy efficient chemical reaction to continue.
10. Slide 9: CARBON NANOTUBES
1)Carbon nanotube is the main concept behind paper battery
2) Carbon nanotubes (CNTs; also known as buckytubes)
are allotropes of carbon with a cylindrical nanostructure. Allotropes
are different structural modifications of an element
3) CNTs exhibit extraordinary strength and unique electrical properties,
and are efficient thermal conductors.
3) Nanotubes are members of the fullerene structural family. The
diameter of a nanotube is on the order of a few nanometers Their
name is derived from their long, hollow structure with the walls formed
by one-atom-thick sheets of carbon, called graphene. These sheets are
rolled at specific and discrete angles, and the combination of the
rolling angle and radius decides the nanotube properties
11. Slide 10: GENERAL Li-ION BATTERY
1) Generally Li-ion re-chargeable batteries are used in
mobiles,laptops and most of the electronic devices.
2) 3 primary functional component of Li-ion battery are:
a) -ve electrode(graphite)
b) +ve electrode(cobalt oxide)
c)electrolyte( lithium salt in organic solvent)
d) During discharge and charging, lithium ions Li+ carry
the current from the negative to the positive
electrode and vice-versa respectively, through the
non-aqueous electrolyte
12. Slide 11: Environmental Impact
• Comparison of paper batteries with traditional batteries in terms
of environmental impact
• Reduction of electronic waste
13. Slide 12: CONSTRUCTION OF PAPER
BATTERY
1) CNT thin films were coated onto stainless steel (SS)
substrates with a solution based process.
2) The concentration of CNT is 1.7 mg/mL.
3) A dried 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.
3)These films act as electrodes of paper battery.
4) one film is pasted to electrolyte LTO (Li4Ti5O12) and the
other film is pasted to electrolyte LCO (LiCoO2).
5) Paper is sandwiched between two electrolytes LTO and
LCO with PVDF(poly vinylidene fluoride) acting as glue.
14. Slide 13: Paper battery offers future power
1)The black piece of paper can power a small light.
2) Flexible paper batteries could meet the energy demands of
the next generation of gadgets.
3)The ambition is to produce reams of paper that could one day
power a car.
4)The paper battery was a glimpse into the future of power storage.
