The document describes a paper battery, which combines carbon nanotubes with conventional paper to create a flexible energy storage device. A paper battery functions as both a battery and supercapacitor, providing both steady power and bursts of energy. It integrates all battery components into a single paper structure, making it more energy efficient than conventional batteries. The document outlines the properties of cellulose paper, how paper batteries work, their construction process, applications, and advantages such as being biodegradable and flexible, as well as disadvantages like the expense of carbon nanotubes.

3.  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 both a high-energy battery and
supercapacitor , combining two components that are separate in
traditional electronics .
 This combination allows the battery to provide both long-term,
steady power production and bursts of energy.

4.  High Tensile strength; Low Shear Strength
 Biodegradable
 Biocompatible
 Excellent Porosity & Absorption Capacity
 Easily Reusable and Recyclable
 Non –Toxic

5.  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.
 The research appears in the Proceedings of the
National Academy of Sciences (PNAS).
 "Think of all the disadvantages of an old TV set with
tubes," said Professor Linhardt, from the New York-
based institute, who co-authored a report into the
technology.

6.  A very brief explanation has been provided.
 • Cathode: Carbon Nanotube (CNT)
 • Anode: Lithium metal (Li+)
 • Electrolyte: All electrolytes (incl. bio
electrolytes like blood, sweat and urine)
 • Separator: Paper (Cellulose)

7.  Step 1: Black carbon ink is applied on a
cellulose-based paper.
 Step2: Black carbon ink is being spread on
a paper spread on the paper.
 Step3: A thin lithium film is laminated over
the exposed cellulose surface.
 Step4:The cellulose paper is heated at 800C
for 5 minutes.

8.  Step5: Next, the film is peeled off from the
substrate
 Step6: The film acts as electrodes of the
paper battery. One film is connected to the
electrolyte LTO (Li4Ti5012) and another film
is pasted to the electrolyte LCO (LiCo02).
 Step7: Next, Connect a LED on both the
ends of the battery and check its
functionality.

11.  Biodegradable & Non Toxic
 Reusable & Recyclable
 Durable
 Rechargeable
 No Leakage & Overheating
 Very Light Weight & Flexible

12.  Carbon nanotubes are very expensive.
 Batteries with large enough power are
unlikely to be cost effective.
 Should not be inhaled as they can damage
the lungs.
 Theses batteries generate e-wastage.

13.  One of the major problems bugging the world
now is Energy crisis.
 Every nation needs energy and everyone needs
power.
 And this problem which disturbs the developed
countries perturbs the developing countries like
India to a much greater extent.
 Paper Batteries can provide an altogether path-
breaking solution to the same.
