    INTRODUCTION

    PAPER THIN BATTERY is developed byresearchers at RENSSELAER POLYTECHNICINSTITUTE.

    Completely integrated. It can be printed like paper and rolled,twisted,folded, or cut into any number ofshapes with no lossof mechanical integrity or efficiency.

    It isenvironmentally

    safe

    .

    The device has blackcolor due to CARBONNANO TUBES.

    Capability to use human blood,sweat or urine tohelp power the battery.

    DEVELOPMENT

    The creation of this device begins from Aug2007.

    The expertise persons of material science,

    energy storage and chemistry, nanotechnologists,and Engg involved in fabrication of this device.

    The researchers used ionic liquid, essentially aliquid salt, as the electrolyte.

    The use of ionic liquid also makes the batterybiocompatible.

    This energy storage device is based on two basic,inexpensivematerials: carbonnanotubes and cellulose.Also an ionic

    liquid provides the third component: electrolyte. Engineered

    together, they form nanocomposite paper. It is as thin and

    flexible as a piece of paperit can be twisted,folded,rolledand

    cut to fit any space without losing any ofits energy.The paperbattery can also be stacked to boost the total power output.

    Li-ion BATTERY

    A lithium-ion battery (sometimes Li-ion battery)is a type of rechargeable battery in which

    lithium ions move from the anode to the

    cathode during discharge, and from the cathode

    to the anode when charged.

    Produced at the rate of2.4 billons unit per year

    to power phones, laptops and other portableelectronic devices.

    Long cycle life and high energy density. 10

    Disadvantages ofLi-Ion

    EXPENSIVEEXPENSIVE -- 40% more than PTB.

    DELICATEDELICATE -- battery temp must bemonitored from within (which raises

    the price), and sealed particularly well.

    REGULATIONSREGULATIONS -- when shippingLi-Ion batteriesin bulk(which also

    raises the price).

    TOXIC AND EXPLOSIVE -- Itaffects the environment.

    ADVANTAGES/CHARACTERISTICS

    y The batterys prime advantage is that it is thinand flexible.

    y

    The 1.5-5v battery generates electricity at astable rate across a wide temperature and

    humidity range without any environmentally

    harmful byproducts.

    y The device can function in temperatures of 300

    degrees Fahrenheit(1480C) and down to 100 below

    zero(-730

    C). 13

    14/23

    y Engineered to function as both a battery and a

    super capacitor.

    y The batteries are rechargeable, can be recharged

    in about 30 seconds.

    y Thin-film cells can be stored for decades(10years).

    y It can be easily recycled.

    y It is dis osable with household wastes. 14

    DISADVANTAGES

    y

    Materials which chemically react, to generatecurrent, dissipate fairly quickly.

    y The use ofnanotubes is very expensive, and would

    not be practical for use in most applications where amore inexpensive power source can be used.

    APPLICATIONSy Power papers can be laminated onto smart cards

    and other micro devices and replace ordinary ticketsand tags.

    y

    In medical devices. Ex; pacemaker.

    y The possibilities of application are endless for using

    Power Paper batteries in novelty items, greeting

    cards.

    y It can be used for memory storage and micro

    processing. 16

    CONCLUSION

    With thin batteries already in commercial use, it is easy tosee them expanding into our everyday lives very soon. They

    have the ability to make our portable devices smaller,

    lighter, and may even power them longer, while

    recharging faster. This technology is not that far offinour future. It will surely be embraced by the public becauseofits "green" aspects. Most of these thin batteries aremade of organic, safe materials, and in many applications they

    will help to minimize waste.
