INTRODUCTION OF PAPER BATTERY:

WHAT IS A PAPER BATTERY?

A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotube with a conventional sheet of cellulose-based paper.

A paper battery acts as both a high-energy battery and super-capacitor , combining two components that are separate in traditional electronics .

Li-ION BATTERY

Generally Li-ion re-chargeable batteries are used in mobiles,laptops and most of the electronic devices.

During discharge and charging, lithium ions Li+ carry the current from the negative to the positive electrode and vice-versa respectively, through the non-aqueous electrolyte .

DISADVANTAGES OF Li-ION BATTERY

EXPENSIVE -- 40% more than NiCd.

DELICATE -- battery temp must be monitored from within (which raises the price), and sealed particularly well.

REGULATIONS -- when shipping Li-Ion batteries in bulk (which also raises the price). Class 9 miscellaneous hazardous material

WHY TO USE PAPER BATTERY?

Ultra-thin size & flexible structure

Operating temperature(-75 to 100 degrees celsius Provide both long-term, steady power production and bursts of energy. Cost effective

CARBON NANOTUBES

Carbon nanotube is the main concept behind paper battery

Carbon nanotubes (CNTs; also known as buckytubes) are allotropes of carbon with a cylindrical nanostructure. Allotropes are different structural modifications of an element

CNTs exhibit extraordinary strength and unique electrical properties, and are efficient thermal conductors.

STRUCTURE OF CARBON NANOTUBES

CONSTRUCTION OF PAPER BATTERY

A piece of paper ink infused with carbon nanotubes and silver nanowires is applied

A small square of ordinary paper with an ink will deposit carbon nanotubes and silver nanowires on the surface that can then be charged with energy to create a battery.

It turns into a battery or super capacitor..

MANUFRATURING PROCEDURE

STRUCTURE OF PAPER BATTERY

WORKING OF A PAPER BATTERY

The battery produces electricity in the same way as the conventional lithium-ion batteries

The devices are formed by combining cellulose with an infusion of aligned carbon nano tubes

The carbon gives the batteries their black color

ADVANTAGES

The flexible battery can function even if it is rolled up, folded or cut. Light weight and low cost

.It generates close to 1.5V of energy.

A paper battery can be used both as a capacitor and battery

LIMITATIONS

Carbon nano tubes are very expensive,

The idea is still in the labs and a commercially viable paper battery will take at least 40-60 years to become a reality.

Cutting of trees leading to destroying of the nature.

APPLICATIONS

PAPER BATTERY OFFERS FUTURE POWER

The black piece of paper can power a small light. Flexible paper batteries could meet the energy demands of the next generation of gadgets

The paper battery was a glimpse into the future of power storage.

These are the power source to next generation electronic devices, medical devices, pace makers, hybrid vehicles, etc.

CONCLUSION Small piece of Paper Battery provides more energy and it is eco-friendly. So Paper Battery can be used for future purpose instead conventional batteries

The batteries are rechargeable, and have reduced cost and weight which in itself may give birth to new applications

Paper battery could solve all the problems associated with electrical energy storage
