The document presents information about paper batteries. It discusses that a paper battery combines carbon nanotubes with conventional paper to create an ultra-thin, flexible energy storage device. It functions as both a high-energy battery and supercapacitor. Paper batteries are cost-effective, flexible, and can operate at a wide temperature range. They work through the interaction of electrolytes during charging and discharging of electrons, similar to traditional batteries. Potential applications include powering small electronics or pacemakers.

2. 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.
A paper battery acts as both a high-energy battery and super-
capacitor , combining two components that are separate in
traditional electronics .
WHAT IS A PAPER BATTERY?

3. GENERAL Li-ION BATTERY
 Generally Li-ion re-chargeable batteries are used in mobiles, laptops and
most of the electronic devices.
 3 primary functional component of Li-ion battery are:
1. -ve electrode(graphite)
2. +ve electrode(cobalt oxide)
3.electrolyte( lithium salt in organic solvent)
 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 .

4. Disadvantages of Li-Ion
• 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).

5. WHY TO USE PAPER BATTERY?
 Ultra-thin size & flexible structure.
 Exhibits property of super-capacitor(22F-36F per gram)
 Operating temperature (-75 to 100 degree celsius)
 provide both long-term, steady power production and bursts
of energy.
 Cost-effective.

6. CARBON NANOTUBES
 Carbon nanotube is the main concept behind paper battery
 Carbon nanotubes (CNTs; also known as buckytubes)
are allotropes of carbon with a cylindrical nanostructure.
Allotropes are different structural modifications of an element
 CNTs exhibit extraordinary strength and
unique electrical properties, and are efficient thermal
conductors.
 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

16. WORKING
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 chemical
reaction to continue.
1.While a conventional battery contains a number of separate components,
the paper battery integrates all of the battery components in a single
structure, making it more energy efficient.

17. • 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.
• "If we stack 500 sheets together in a ream, that's 500 times
the voltage. If we rip the paper in half we cut power by 50%.
So we can control the power and voltage issue."
• Because the battery consists mainly of paper and carbon, it
could be used to power pacemakers within the body where
conventional batteries pose a toxic threat.
