2. So, What is Graphene ?

3. Graphene
• Graphene can be described as an one atom thick of
graphite.
• It is the basic structural element of other allotropes,
including graphite, charcoal, carbon nanotubes and
fullerenes.
• Graphene is the strongest, thinnest material known to
exist.
• World’s first 2-dimensional material.

4. Facts first!
• Thickness of human hair, 0.04
mm to 0.12 mm(diameter).
• Graphene is 0.35 to 1 nm thick.
1 mm = 1,000,000 nm

6. Discovery of Graphene
• It was originally observed in electron microscopes in
1962, but it was studied only while supported on
metal surfaces.
• The material was later rediscovered, isolated, and
characterized in 2004 by Andre Geim and Konstantin
Novoselov at the University of Manchester.
• This work resulted in the two winning the Nobel
Prize in Physics in 2010 “for groundbreaking
experiments regarding the two-dimensional material
graphene”.

7. What makes this material so special?

8. Properties of Graphene
• Thinnest material in the world.
• It is almost entirely transparent.
• Best conductor of heat.
• Best conductor of electricity, 100 times faster than copper.
• Is one of the best flexible material.
• Has great elasticity.
• Is totally impermeable to even smallest atom(helium).
• 200 times stronger than Steel.
• Electron mobility is 140 times faster than silicon.

12. Graphene Batteries

13. Why Battery ?

14. • There are around 4.77 billion mobile phone users in the world.
• Out of this 4.77 billion users 95% of the people have the “low
battery anxiety”.
• Nomophobia is a proposed name for the phobia of being out
of cellular phone contact.

17. Graphene Battery by SAIT
• SAIT developed Graphene ball a unique
material that enables a 45% increase in the
capacity of the battery and five times faster
charging speed.
• In theory, a battery based on the “graphene
ball” material requires only 12 minutes to fully
charge.
• Additionally, the battery can maintain a
highly stable 60 degree Celsius and as low as
–30 degree Celsius temperature, with stable
battery temperatures particularly key for
electric vehicles.

18. So, will graphene bring a revolutionary
change in the tech field?

19. Big Yes!

21. This material may rule to world!
