In August 2007, professors Ann and John H. Broadbent and Omkaram Nalamasu developed a paper battery, also known as a nano-composite paper. A paper battery is a flexible, ultra-thin energy storage device formed by combining carbon nanotubes with conventional cellulose-based paper. To create a paper battery, carbon nanotube ink is applied to paper using a coating method, then a thin lithium film is laminated over the paper to complete the battery, which can then be connected to external loads. Paper batteries produce electrons through a chemical reaction between the electrolyte and carbon nanotubes, and can be folded, cut, or otherwise shaped without losing efficiency.

3. In august 2007, a research team of
senior professors “Ann and John
H.BroadBent, Omkaram Nalamasu”
developed the paper battery…
It is also known as “nano
composite paper.”

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.
What is a paper battery????

5. The process of construction can be
understood in the following steps:
• Firstly, a common Xerox paper of desired shape and
size is taken.
• Next, by conformal coating using a simple Mayer rod
method, the specially formulated ink with suitable
substrates (known as CNT ink) is spread over the paper
sample.

6. • The strong capillary force in paper enables high
contacting surface area between the paper and nanotubes
after the solvent is absorbed and dried out in an oven.
• A thin lithium film is laminated over the exposed
cellulose surface which completes our paper battery. This
paper battery is then connected to the aluminium current
collectors which connect it to the external load.
• The working of a paper battery is similar to an
electrochemical battery except with the constructional
differences.

8. 1.Batteries produce electrons through a chemical reaction between electrolyte
and metal in the traditional battery.
2. Chemical reaction in the paper battery is between electrolyte and carbon
nanotubes.
3. Electrons collect on the negative terminal of the battery and flow along a
connected wire to the positive terminal
4. Electrons must flow from the negative to the positive terminal for the
chemical reaction to continue.
Working:

9. DURABILITY:
Paper batteries may be
folded, cut or otherwise
shaped for different
applications without any
loss of integrity or efficiency

10. Cutting one in half
halves its energy
production.
Stacking them
multiplies power
output.

11. The components are molecularly
attached to each other

12. The carbon nanotube print is embedded
in the paper and the electrolyte is soaked
into the paper

13. It is highly used
in many fields
such as in
cosmetics,
Micro processor,
thin display,
functional card,
elecronic
appliances
etc…..
USES:

14.  Powered smart cards RF id tags
 Pace makers in heart (uses blood as
electrolyte)

15. Paper batteries recharge themselves from
the moisture in the air

16. These are environmentally friendly
and can be recycled
