A Conventional Battery takes up a huge amount of space and contributes to a large part of the device's weight.

Paper Battery is flexible and ultra thin energy storage device. It acts as both high-energy battery and super-capacitor. This combination allows the battery to provide both long term, steady power production of energy.

It can be folded, cut or otherwise shaped for different applications with out loss of efficiency. Cutting one in half, halves its energy production.

1Abstract

Paper Batteries will replace the conventional batteries and Li-ion batteries

1Introduction

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 on carbon nano tubes easily

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

1Introduction

Cellulose paper + Nano Technology = Paper Battery

2Working

Conventional 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

2Development

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 -75C to 150C

3Applications

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)

It can be Rolled, twisted, folded or cut into numerous shapes

No loss of integrity/efficiency

Light weight

Bio-degradable and Non-toxic

It can be a Super Capacitor

3Advantages

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 old electronic goods

3Disadvantages

The life of battery is an important parameter which decides the area of application of battery.

These paper batteries can further reduce the weight of the electronic gadgets.

The future may allow simply painting the nano-tube ink and active materials onto surfaces such as walls.

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

! Conclusion

Saving energy is the best way

to re-cycle the energy
