What is A PAPER BATTERY?A paper battery is a flexible, ultra-thin

energy storage and production device

formed by combining carbon nano tubes with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and super capacitor . A new energy storage device, that is only slightly bigger than the size of a stamp and can be bent and twisted, trimmed with scissors or molded into any needed shape. More than 90 percent of the device is made up of cellulose ,about 0.025mm thick.These are flexible and can be recharged in about 30 seconds

HISTORY

The creation of this unique

nano composite paper drew from a

diverse pool of disciplines, requiring

expertise in materials science, energy storage, and chemistry

It is Created in 2007 by a group of students at the Rensselaer Polytechnic Institute in Troy, New York,

The continuously advancing technology of portable electronic devices asks for more flexible batteries to power them. Here is an ultra-thin and flexible quick

charging battery named ORB, for Organic Radical Battery, a new energy storage device, that is only slightly

bigger than the size of a stamp and can be bent and twisted, trimmed with scissors or molded into any needed

Shape .

Preparation of paper battery Its easy and effective to prepare paper

batteries

Dip an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, and it turns into a battery or supercapacitor.

WORKING

Chemical reaction in the paper battery is between electrolyte and carbon nano tubes.

Electrons collect on the negative terminal of the battery and flow along a connected wire to the positive terminal, Batteries produce electrons through a chemical reaction between electrolyte and metal in the traditional battery. Electrons must flow from the negative to the positive terminal for the chemicalreaction to continue. Ionic liquid, essentially a liquid salt, is used as the battery's electrolyte. Ionic liquid contains no water, which means there's nothing in the batteries to freeze or evaporate therefore allowing the paper energy storage devices to withstand

ESSENTIIAL FEATURES OF PAPER BATTERIES

Paper batteriesLighter than metals

Low maintainence

Non toxic and biodegradable

No electrolytic leakages and battery failures

Non fragile

Can be operated at extreme temperatures

Paper battery is extremely flexible as carbon nano tubes are used as the electrodes.

The paper-like quality of the paper battery along with the nano tubes embedded in them gives them light-weight and are low-cost.

. The paper battery are also used for medical devices because of their ability to use electrolytes in the blood.

ADVANTAGES OF PAPER BATTERY :

The invention of the paper battery has been hailed as an efficient "green," or environmentally friendly, technology.

The battery, which is made of up to 90 percent cellulose, is no thicker than a common sheet of printer paper, about .025 mm (.00098 inches) thick. Because of its composition, the paper battery is completely non-toxic and fully biodegradable.

The battery functions as a lithium-ion battery and also as a super-capacitor. It can provide a long and a steady power output as compared to the conventional battery.

A paper battery is different from the conventional battery in the sense that it integrates all the battery components in a single structure. Paper battery is therefore more energy efficient.

Technical advantages of paper batteries "They're a one-dimensional structure with very small diameters.“

The small diameter helps the nanomaterial ink stick strongly to

the fibrouspaper, making the battery and supercapacitor very

durable.

The paper supercapacitor may last through 40,000 charge-

discharge cycles – at least an order of magnitude more than

lithium batteries.

The nanomaterials also make ideal conductors because they move

electricity along much more efficiently than ordinary conductors,

DURABILITYPaper battery is extremely flexible as carbon nanotubes are used as the electrodes. The sheets can be rolled, twisted, folded and cut into various shapes with no loss in quality and efficiency. The components are attached to each other and the carbon nanotube print is embedded in the paper and the electrolyte is soaked in the paper which looks the same like a paper.

Disadvantages of paper batteries

Threats of paper cut

Normal paper is not water proof

Easily flammable

Paper becomes weak over time so it has a life time limit

Not strong enough for heavy duty work

If recycling includes deinking it creates effluence

Printing of new paper needs trees to be cut down

Applications of Paper batteries . The paper battery are also used for medical devices because of their

ability to use electrolytes in the blood

The flexible shape of paper battries will allow it to be used in irregular electronics

The paper battery could replace the conventional battery

In futre it will be able to supply the power to an implanted pacemaker in human body by using electrolytes in human blood

The future paper battery will be capable of being made into a super capacitor or rechargable battery

The paper battery can be operated in extreme temperatures ranging from -73 to +148 degree celcius

Its low cost of manufacturing finds use in several electronic applications

It can be used in car doors which would power up the components like air bags etc..

It is easily transpotable and can be twisted or folded

These batteries do not contain caustic chemicals and do not overheat or explode or produce electrical shock so these can be easily shipped and stored and disposed after use

As the components are bio degradable paper batteries are eco friendly

Paper batteries are used in cosmetis

In preparation on thin displays

Conclusion Through the whole research I come to the

conclusion that paper batteries are cheap and better source of power generation and are environment friendly than present lithium ion battries .paper battries made of silicon are 10 times more powerful than the lithium ion battries so future power is dependent on paper battries for a better future
