A paper battery is a flexible energy storage device formed by combining carbon nanotubes with conventional cellulose-based paper. It acts as both a high-energy battery and super-capacitor. Paper batteries are made using a cathode, anode, carbon nanotubes, and an ion-based liquid electrolyte. They are inserted between the paper layers. Paper batteries offer advantages like flexibility, ultra-thinness, long life, safety, steady power production, and light weight. However, they are prone to tearing and the nanotubes used are expensive to produce. Potential uses include powering smart tags, medical devices, and making interactive gaming cards.

2. Introduction
 A paper battery is an energy storage device.
 It is used as a battery and also as a good
capacitors.
 It is formed by combining two things which are
carbon nanotubes and the cellulose based
paper.

3. Definition of paper battery
 Paper Batteries are made using a combination of
nanotubes made from carbon and paper made from
cellulose
 The process to make paper batteries start with making
a cathode and anode from manganese dioxide and zinc.
 The nanotoubes made from carbon are then added.
 The electrolyte is an ion based liquid solution.

4. • A paper battery is a flexible, ultra-thin energy storage
and production device formed by combining carbon
nanotubes with a conventional sheet of cellulose-based
paper.
• A paper battery acts as a both high-energy battery and
super-capacitor, combining two components that are
separate in traditional electronics.

5. • Carbon nanotubes is the main
concept behind paper battery.
• Carbon nanotubes(CNTs; also known
as buckytubes) are allotropes of carbon
with a cylindrical nanostructure.
• CNTs exhibit extraodinary strength and
unique electrical properties, and are
efficient thermal conductors.

9. • LTO(Lithium titanate oxide) & LCO(Lithium cobalt oxide).

11. • Used as both battery and capacitor.
• It is flexible.
• It is ultra thin energy storage device.
• Long lasting.
• Non toxic.
• Steady power production.
• High efficiency.
• Available in different sizes.
• It is light weight.
• it is more economical.
• Can be easily disposed.
• Can be recharged.

12. DISADVANTAGE
 Prone to tearing.
 Nanotubes made from carbon are expensive due
to use of procedures like electrolysis and laser
ablation.
 Should not be inhaled, as they can damage
lungs.

13. PRATICAL USES
 Can be used to power smart tags.
 Can be used to power signal use medical
devices.
 Can be used to make items like gaming cards
interactive at very low cost.
