1 : Introduction

• 2.1 : Carbon nanotube’s

• 2.2: Manufacturing Process

2

: Formation of Battery

3 : Working

4 : Advantages

5 : Application



• Flexible, ultra-thin energy storage and production

device.

• Formed by combining carbon nanotubes with aconventional sheet of cellulose-based paper.

• A paper battery acts as both a high-energy battery

and super capacitor.

• This combination allows the battery to provide bothlong-term, steady power production and bursts of

energy .



• Can be folded, cut or otherwise shaped for different

applications without any loss of efficiency.

• Can be stacked in multiples of power output.

• 2.5 volts of electricity from a sample the size of a

postage stamp.



• Combining cellulose with an infusion of aligned

carbon nanotube’s that are each approximately

one millionth of a centimeter thick

•

These tiny filaments act like the electrodes foundin a traditional battery, conducting electricity

when the paper comes into contact with an ionic

liquid solution.

• With no water in solution, cannot freeze andhence operating temp -75 to 150 Degree Celsius



• Carbon nanotubes (CNTs; also known

as buck tubes) are allotropes of carbon witha cylindrical nanostructure.

• They exhibit extraordinary strength andunique electrical properties, and areefficient thermal conductors.

• Nanotubes are members of

the fullerene structural family, the diameterof a nanotube is on the order of a fewnanometers



• Because of the symmetry and unique

electronic structure of graphene, the structureof a nanotube strongly affects its electricalproperties. For a given (n ,m ) nanotube,if n = m , the nanotube is metallic; if n − m is a

multiple of 3, then the nanotube issemiconducting with a very small band gap,otherwise the nanotube is amoderate semiconductor.



Growing the nanotube’s on a silicon substrate and thenfilling the gaps in the matrix with cellulose.

Once the matrix has dried, the material can be peeledoff of the substrate, exposing one end of the carbon

nanotube’s to act as an electrode .When two sheets are combined, with the cellulose

sides facing inwards, a super capacitor is formed thatcan be activated by the addition of the ionic liquid.

This liquid acts as an electrolyte and may include salt-laden solutions like human blood, sweat or urine.



• While a conventional battery contains a number of

separate components, the paper battery integrates all

of the battery components in a single structure,making it more energy efficient.

• INTEGRATED DEVICES – No warm up time, power

loss, component malfunction; Loss of energy whiletransferring power from one component to another,less energy lost in an integrated device

Batteries produce electrons through a chemicalreaction between electrolyte and metal in thetraditional battery.

Chemical reaction in the paper battery is betweenelectrolyte and carbon nanotubes.

Electrons collect on the negative terminal of thebattery and flow along a connected wire to thepositive terminal

Electrons must flow from the negative to thepositive terminal for the chemical reaction tocontinue.



5 : APPLICATIONS…

• The paper-like quality of the batterycombined with the structure of thenanotubes embedded within - light weightand low cost.

Cosmetic path: paper battery is set iniontophoresis patch for whitening andwrinkles.

• Medical path: paper battery is set iniontophoresis patch. It helps to deliverfunctional drug i.e., local anaesthesia,antichloristic , anodyne, etc.. Into skin.



• RFID tag: paper battery is useful to use as apower source of active RFID tag.

• Functional card: paper battery is possible touse as a power source of melody and displaycard.

• Micro processor; paper battery supply power tomicro processor.

• Ability to use electrolytes in blood make thempotentially useful for medical devices such aspacemakers .
