Introduction

O A Paper battery is the flexible, ultra thin energy storage and Production device.

O Formed by combining carbon Nano tubes.

O Acts as both high energy battery and super capacitor.

O Non-toxic, flexible paper batteries have the potential to power the next generation of electronics.

O Paper batteries may be folded or otherwise shaped for different applications.

O No loss of integrity or efficiencyO Cutting one in half halves its energy

productionO Stacking them multiplies power output.O Early prototypes of the device are able

to produce 2.5 volts of electricity from a sample the size of a postage stamp.

History of Paper Batteries

O Widespread commercial deployment of paper batteries will rely on the development of more inexpensive manufacturing techniques.

O A paper battery powered by ionic solutions is developed in 2005.

O Specialized paper batteries could act as power sources for any no. of devices.

O Biodegradable.

DEVELOPMENTO In 2005 RPI & MIT, researchers in

Singapore developed a paper battery powered by ionic solutions.

O NEC has also invested in R&D into paper batteries.

O First development of paper batteries has been done by the scientists at Rensselaer polytechnic institute.

O The development of paper batteries begins with growing the nanotubes on a silicon substrate & then impregnating the gaps in the matrix with cellulose.

DURABILITY

O The spacer is an integrated combination of spacer, & electrodes.

O The components are molecularly attached to each other.

O The carbon Nano tube print is embedded in the paper,

O Electrolyte is soaked into the paperO The end result is a device that looks ,

feels and weighs the same as paper.

USESO Light weight and low cost.O Ability to use electrolytes in blood.O Useful for medical devices such as

pacemakers.O Medical uses are particularly attractive.O They do not contain any toxic materials .O Biodegradable.

Conclusion

The commercial applications may be a long way away.

Nano tubes are still relatively expensive to fabricate.

O The voltage could be large enough to POWER a CAR.

O We can design the Nature friendly equipment's that can cause no harm to the nature.

O Hence we can protect our nature from GLOBAL WARMING.
