Why are Graphene batteries not here
yet?: In this article, we will look at why is graphene batteries and products
revolutionary and why are they not here yet even after two decades after their
discovery.
Why are Graphene batteries not here yet? :
Graphene
is one of the revolutionary discoveries in the past two decades, When it
was discovered in 2004, The scientists who discovered it received a noble prize because of its wonder properties
which can be applied in a lot of products in consumer electronics and
ever since the world it been waiting for its arrival.
One of the
most attractive properties of graphene is its application in battery
technology, graphene has one of the largest surface areas in any
compound and its good conductivity of heat and electricity makes it the
best substance for
battery manufacturing.
The main drawbacks
of li-ion and the other types of batteries are fragility, require a protection circuit to maintain safe operation,
lower speed of power transfer, Heavier, and not being a very good
conductor of heat, and these drawbacks have led to a lot of
accidents.
On the other hand, graphene pretty much
covers up all these drawbacks of li-ion, By increasing the
power transfer
speed by 8-15 times the traditional speeds of li-ion and by being
cooler while doing so. And because of its
lighter form factor, this can be used in car batteries, which until
now is one of the heaviest parts of an
electric car.
So why is it fully not out yet?:
Graphene might seem like a
substance that can be obtained easily by a cello tape and a block of
graphite, But the reality of making it mass produced is harsh,
That is the raw material to graphene ratio is high and the raw
material itself is expensive to actually get pure and
uncontaminated graphene.
But new ways are getting
discovered in recent years to mass produce graphene to make it feasible
for making consumer electronics.
