BATTERY

The Batteries form a significant part of manyelectronic devices.

Typical electrochemical batteries or cellsconvert chemical energy into electricalenergy.

Electrons flow from the negative terminaltowards the positive terminal.

DEMERITS OF TRADITIONAL BATTERIES

WHAT IS A PAPER BATTERY?

A paper battery is a flexible, ultra-thin energy

storage and production device.

Paper battery (PB)= Paper (Cellulose) +

Carbon nanotubes (CNT)

It act as high Energy Battery & Super Capacitor due

to combining of two discrete components.

CARBON NANOTUBES

Carbon nanotubes (CNTs) are allotropes of carbon with acylindrical nanostructure

PROPERTIES OF NANOTUBES

High tensile Strength (Greater than Steel).

Low Mass density & High Packing Density.

Very Light and Very Flexible.

Very Good Electrical Conductivity

NANO TECHNOLOGY

Nano technology is art of science & manupilating

matter at nanoscale

It is the study of making small microscopic things

It is advance technology to the future

Nanotubes are categorized as Single wall nanotubes

(SWNTs) and Multiwallednanotubes (MWNTs)

CONSTRUCTION OF PAPER BATTERY

FABRICATION OF PAPER BATTERY

Materials Required :

1. Copier Paper

2. Carbon Nano Ink

3. Oven

4. Lithium

Step 1: The copier paper is taken

Step 2: Carbon Nano ink which is black in color is

taken. Carbon Nano ink is a solution of Nano rods,

surface adhesive agent and ionic salt solutions.

Carbon Nano ink is spread on one side of the paper

Step 3: The paper is kept inside the oven at

150C temperature. This evaporates the water

content on the paper. The paper and the Nano

rods get attached to each other.

Step 4: Place the multi meter on the sides of the

paper and we can see voltage drop is generated.

WORKING OF PAPER BATTERY

Cathode: Carbon Nano tubes

Electrolyte: All electrolytes

Separator: Paper (Cellulose)

Anode: Lithium metal (Li+)

Biodegradable & Non Toxic

Reusable & Recyclable

Durable

Rechargeable

No Leakage & Overheating

Very Light Weight & Flexible

ADVANTAGES OF PAPER BATTERY

The production of Carbon Nanotubes are very

Expensive and very less Efficient

Have low Shear Strength

APPLICATIONS Smart Cards and tags.

Wrist Watches

Wearable Computers

CONCLUSION

Paper battery plays an impact role to avoid the

maximum interrupted power supply in our

world.

By using this battery in electronic equipment

we can reduce the Occupying space of alkaline

& lithium batteries
