What is paper battery?

A paper battery is flexible,

ultra-thin energy storage device

Paper battery= paper(cellulose) +

carbon nanotubes.

Cellulose Cellulose is an organic

compound with the

formula(C6H10O5)n

Cellulose is an importantstructural component of

the primary cellwall of green plants

10

Prpoperties of cellulose

Biodegradable

Biocompatible

Excellent Porosity & Absorption Capacity

Easily reusable and recyclable

Non-toxic

Carbon-nanotubes Carbon

nanotubes (CNTs)are allotropes of carbon.

length-to-diameter ratio ofup to 132,000,000:1

Formed by one-atom-thicksheets of carbon,called graphene. Thesesheets are rolled at specificand discrete angles

Steps involved in construction

Graphene structure Rolled at angle CARBON NANOTUBE

13


14/27

Properties of CNTs The way the graphene sheet is wrapped is represented

by a pair of indices (n,m).

The integers nand mdenote the number of unitvectors along two directions in the crystal lattice ofgraphene.

If m= 0, the nanotubes are called zigzag nanotubes,and if n= m, the nanotubes are called armchairnanotubes. Otherwise, they are called chiral

14


15/27

D=a /3.14 .(n^2 + m^2 + nm )^0.5 pm

where a= 0.246 nm

For a given (n,m) nanotube,

if n= m, the nanotube is metallic

if nmis a multiple of 3, then the nanotube is

semiconducting with a very small band gap

otherwise the nanotube is a moderate semiconductor

18/27

Output circuit voltage

It is 1.5-2.5V for a postage stamp sized specimen.

Can be varied by two methods: CNT Concentration

Stacking and slicing of paper

Advantages

Biodegradable

Biocompatible

Durable

No leakage and overheating

Very light weight and flexible

Easily moldable into desired shapes and sizes.

19


20/27

Disadvantages

Low shear strength

Techniques and set-ups used in production of CNTs

are very expensive.

Injurious to health if inhaled.

Works efficiently at small scale only.

20


21/27

Applications

Used in laptop batteries, mobile phones, digital

cameras.

In calculators, wrist watches and other low drain

devices.

In wireless communication devices.

In enhanced PCBs

21


22/27

In pacemaker for heart

In biosensors , such as glucose meter , sugar meter etc.

For light weight guided missiles.

For powering electronics devices in satellite program.

22


23/27

In Pacemakers Blood acts as an

electrolyte.

Sodium , potassium ,chlorides & bicarbonates

will recharge battery

Conclusion

Having excellent features paper batteries have

potential adaptability to power the next generation

electronics.

Energy crisis solutions

Can overcome many disadvantages of traditional

batteries.
