WORKING OF

PAPER BATTERY

The devices are formed by combining cellulose

with an infusion of aligned carbon nanotubes.The carbon is what gives the batteries their black

color.

The battery produces electricity in thesame way as the conventional

lithium-ion batteries that power somany of today's gadgets, but all thecomponents have been incorporatedinto a lightweight, flexible sheet of

paper.

These tiny filaments act like theelectrodes found in a traditionalbattery, conducting electricity when

the paper comes into contact with anionic liquid solution.

Ionic liquids contain no water, whichmeans that there is nothing to freeze

The paper is made conducting material by dipping in ink.The paper works as a conductive layer. Two sheets ofpaper kept facing inward act like parallel plates (highenergy electrodes). It can store energy like a supercapacitor and it can discharge bursts of energy because oflarge surface area of nano tubes.

or evaporate in extreme environmental conditions. As a result,paper batteries can function between -75 and 1500C.

The flexible shape allows the paper battery to be

used small or irregularly-shaped electronics: One of the unique features of the paper battery is

that it can be bent to any such shape or design thatthe user might have in mind. The battery can easily

squeeze into tight crevasses and can be cut multipletimes without ruining the battery's life. For exampleif a battery is cut in half, each piece will function,however, each piece will only contain 1/2 theamount of original power. Conversely, placing twosheets of paper battery on top of one-another willdouble the power.

ADVANTAGES

The paper battery may replace conventional batteries

completely: By layering sheets of this paper, the battery's voltage

and current can be increased that many times. Sincethe main components of the paper battery are carbonnanotubes and cellulose, the body structure of the

battery is very thin, "paper-thin". Thus to maximizeeven more power, the sheets of battery paper can bestacked on top of one another to give off tremendouspower. This can allow the battery to have a muchhigher amount of power for the same size of storage

as a current battery and also be environmentallyfriendly at the same time.

CONCLUSION

We have discussed the various terminologies, principle ofoperation of a battery and recent developments related toit. The life of a battery is an important parameter whichdecides the area of application of the battery. Increased

use of batteries gives rise to E-waste which poses greatdamage to our environment.

In the year 2007 paper battery was manufactured. Thetechnology is capable of replacing old bulky batteries.The paper batteries can further reduce the weight of theelectronic gadgets.

The adaptations to the paper battery technique in the future couldallow for simply painting the nanotube ink and active materialsonto surfaces such as walls. These surfaces can produce energy
