A Conventional Battery takes up a

huge amount of space and contributes toa large part of the device's weight.

Paper Battery is flexible and ultrathin energy storage device. It acts as both

high-energy battery and super-capacitor.This combination allows the battery toprovide both long term, steady powerproduction of energy.

It can be folded, cut or otherwiseshaped for different applications with outloss of efficiency. Cutting one in half,halves its energy production.

Abstract


4/14

Paper Batteries will replace

the conventional batteries

and Li-ion batteriesIntroduction

Anatomy of paper battery is based on

the use of Carbon Nano-tubes tiny

cylinders to collect electric charge

Paper as a medium is the well-designed

structure of millions of interconnected

fibers in it. These fibers can hold oncarbon nano tubes easily


5/14

Formed by combining carbon nano-tubes with a

conventional sheet of cellulose-based paper

Nano-tubes acts as electrodes, allowing the

storage devices to conduct electricity

Paper battery integrates all of the battery

components in a single structure, makes

it more energy efficient

Carbon nano-tubes exhibit extra-ordinary

strength and unique electrical properties

Introduction

Cellulose paper + Nano Technology = Paper Battery


6/14

WorkingConventional Battery produce electrons through a

chemical reaction between electrolyte and metal

Chemical reaction in Paper Battery is between electrolyte and

carbon nano-tubes

Electrons must flow from negative to positive terminal for the

chemical reaction

Conventional Battery Vs Paper Battery

The Paper electrode stores charge while

recharging in 10 seconds because ions flow

through the thin electrode quickly

Development

Step 1 Carbonate paper and Carbon nano ink is taken

Step 2 Carbon nano ink is spread on one side of the paper

Step 3 Paper is kept inside the oven at 150C temperature. This

evaporates water content on paper, so that paper and

nano rods get attached each other

Step 4 After drying, the paper becomes flexible, light weight and

can withstand from -75Cto 150C

Applications

As alternate to conventional batteries in gadgets

Powered smart cards RF id tags

E-cards, E-greetings and Talking posters

Pacemakers in the heart (uses blood as electrolyte)


9/14

It can be Rolled, twisted, folded or cut intonumerous shapes

No loss of integrity/efficiency

Light weight

Bio-degradable and Non-toxic

It can be a Super Capacitor

Advantages


10/14

Carbon nano-tubes are very expensive

Batteries with large enough power are unlikely to

be cost effective

For a commercial viabilities, these batteries have

to be scaled up to sheets of newspaper size

Replacing the old batteries results wastage of oldelectronic goods

Disadvantages


11/14

The life of battery is an important

parameter which decides the area ofapplication of battery.

These paper batteries can further reduce

the weight of the electronic gadgets.

The future may allow simply painting thenano-tube ink and active materials onto

surfaces such as walls.

High storage of energy leads to decreasecharging time. Thus energy can be saved

Conclusion

Saving energy

is the best way

to

re-cycle the energy
