Introduction
Our world is moving towards EVs, By 2030 about 40-45%
of transport will be based on EVs. EVs, are automobiles
that are powered by one or more electric motors instead
of an internal combustion engine (ICE) that runs on
gasoline or diesel fuel. EVs rely on rechargeable batteries
to power the electric motor, which then powers the
vehicle's wheels to provide motion. Here the major role is
played by the batteries, As of now most EVs use LithiumIon Batteries.
Issues!
Now the problem we are facing in Lithium-Ion
Batteries are, It occupies more space, weight as
well as more charging time these are the major
parameters which affect user experience
Graphene And Batteries
Graphene, a sheet of carbon atoms bound together in a
honeycomb lattice pattern, is hugely recognized as a
wonder material due to the myriad of astonishing
attributes it holds. It is a potent conductor of electrical
and thermal energy, extremely lightweight chemically
inert, and flexible with a large surface area. It is also
considered eco-friendly and sustainable, with unlimited
possibilities for numerous applications.
“ Graphene can not only conduct
electricity and heat better than
lithium but also do so at a
fraction of the weight.
GRAPHENE vs LI-ION
1. Higher capacity on average than Li-ion batteries.
2. Li-ion batteries can store up to 180Wh per kg, while Graphene
can store up to 1000Wh per kg.
3. Due there flat efficiently conducting structure Graphene batterie
can charge much faster than Li-ion batteries.
4.
Graphene batteries can store more energy than Li-ion batteries.
GRAPHENE vs LI-ION
5. Graphene batteries are more environmentally friendly than
Li-ion batteries.
6. Graphene batteries are less expensive than Li-ion batteries.
7. Graphene batteries are not made up of highly flammable
materials therefore it is much safer than Li-ion batteries
Advantages
LIGHT WEIGHT
FAST CHARGE
Easy to switch from
one place to another
Charge 100% within
15 mins or less
Ability to store more
power than usual
Great thermal
management &
durable
HIGHER CAPACITY
LOW TEMPERATURE
1. Light Weight
Usually Graphene batteries are lighter than Lithium-Ion,
So that they can be easily transported from one place to
another. Lifting a 150v Lithium-Ion battery is impossible
for an individual whereas the same voltage battery
made up of Graphene can be lifted easily. As an added
advantage more storage can be achieved due to its
lightweight, which makes the EVs more suitable for
long-range and more powerful.
2. ASAP
charge
Graphene will make charging EVs really quick, where as other
batteries take one night to get fully charged. Graphene can
charge 500v in around 20 mins.
3. Higher Capacity
Graphene improves a battery surface area.
1.
Because the material is so flexible and features such
as large surface area it is used in complimenting and
supporting Li-ion batteries.
2. Graphene can be coated on essentially any
substrate, lead to better power and energy density.
4. Thermal Management
Graphene is such an excellent conductor; it leads to more
optimized energy transparent performance.It allows
batteries to last for more charge cycles and to charge
more quickly.This leads to efficient, long-lasting batteries
that could open up new possibilities in the world of
technological innovation.Graphene batteries are also
lighter and slimmer than today’s batteries.This allows
larger capacities within small occupying space
Conclusion
Graphene batteries offer several advantages over traditional
Li-ion batteries, including faster charging time, longer
lifespan, increased safety, and better environmental
sustainability. Although graphene batteries are still in the
early stages of development, their potential to revolutionize
the battery industry is significant. As research and
development continue, graphene batteries may become the
go-to solution for powering our devices and vehicles in the
future.
