Hello Everybody and welcome Back
Elon Musk is hyping Tesla’s upcoming Battery
Day – saying that it will be “one of the
most exciting days in Tesla history” and
hinting at a ‘Terafactory’ announcement.
with the legacy automakers struggling to create
Giga factories it's becoming clear that
The gap between Tesla and legacy automakers
is still continuing to widen.
Tesla’s mission is to accelerate the world’s
transition to sustainable energy through increasingly
affordable electric vehicles and energy products
Thus, Gigafactory is Born out of Necessity
to achieve this Goal. It is created to supply
enough batteries to support Tesla’s projected
vehicle demand.
Therefore, It is important to have a basic
idea about Gigafactory Before Understanding
TeraFactories
 The name Gigafactory comes from the word
'Giga,' the unit of measurement representing
“billions.”
Which means that Gigafactory are factories
that produce billions of watt hours in Battery
Capacity.
Tesla's first Giga factory in Reno Nevada
has a production capacity of 35 gigawatt hours
and is the highest volume battery plant in
the world        in hindsight this may
seem like a large amount
however in Tesla's q1 2020 conference call
Elon Musk has recently hinted at an upcoming
TerraFactory,
Let's hear the clip
Musk Hinting at Tera Factory
So, i Believe we'll see Tesla plans to produce
over 1 terawatt-hour of battery cells announced
at the battery investor day.
A terawatt hour is a unit which translates
to 1,000 gigawatt hours in amount that is
over 28 times larger than Tesla's Giga Nevada
Therefore, In this video We will Take a Closer
Look at How can Tesla reach Terawatt Hours
of Production Capacity with the Upcoming Tera
Factory
Also Real quick, I would really appreciate
an early thumbs up as it really helps with
the YouTube Algorithm and these Videos do
take really long time to make,
Thank you and let's Dive right in....
when Tesla first unveiled the Giga factory
Elon Musk stated that they only needed a hundred
Giga factories to transition the world to
being electric,
Let's Hear the clip,
 we actually did the calculations say
like what would it take to transition
the whole world to its sustainable
energy
what kind of throughput would you
actually need and you need 100 Giga
factories
Of course this includes other company's Giga
factories but even With Tesla creating a new
Giga factory every year or two
 it would still take decades for Tesla to
achieve its goals. Obviously, It makes Sense
for tesla To create TeraFactories
Instead of Gigafactories but  Tesla can't
simply just build a building call it a Terra
factory and suddenly have the capacity that
it needs
it's clearly a complex process with manufacturing
equipment that is required as well as Raw
materials needed for batteries,
But If you are tesla then It can be Done in
a Number of ways,
Let's See some of the  ways that Tesla could
Upgrade existing Giga factory into Terra Factory
1. Increase in Production Capacity:
Giga factory One in Reno Nevada has a production
capacity of 35 gigawatt hours.
It means, In one year, the total number of
batteries produced will have combined battery
capacity of 35 Gwh
IF Tesla were to increase the number of batteries
 produced by the factor of 30. that is without
any improvement in energy density or other
aspects of the battery then,
Tesla can reach Terawatt hours of cell capacity
In other words, Tesla would Have Upgraded
The Giga Nevada into Tera Nevada
Remember Tesla acquired two battery companies
Maxwell and hibar, these guys are experts
at Battery Manufacturing Technology
Maxwell Technologies was acquired Primarily
for this cheaper super fast Manufacturing
Technology and
Maxwell claims it to be 16X increase in production
capacity. Which means we can make 16 times
more number of batteries in the same time
period,
And Hibar was Acquired for this super fast
Electrolyte filling technology which increases
the overall Rate of Production.
With the Combination of these two Technologies,
Tesla can pump out way more batteries at incredible
rates which wasn't possible before.
If you want a more In Depth Explanation then
you can watch this Video where we cover all
the major Improvements of Maxwell's Dry electrode
manufacturing Process.
2. Increase in Energy Density
today's Tesla Model 3 2170 battery cells
have about 250 watt hours of energy per kilogram
so in gravimetric
terms this literally means that there is only
250 watt hours of energy in a single kilogram
of mass.
But Tesla's upcoming Terra factory will ultimately
utilize the new technology achieved in Tesla's
secret project codenamed
Roadrunner that looks to bring the Energy
Density from 250wh/kg to at least 300 wh/kg,That
would make Standard Range Model 3 go from
250miles to 300miles  
A denser battery would solve many range and
weight issues of tesla Semi and Cybertruck.
also if a Tesla factory simply outputted more
energy-dense batteries
the factory size wouldn't change but Tesla
would be
a lot closer to a terawatt our number. If

Breakthrough technologies then you can watch

3.Removing Manufacturing Steps:
By using Maxwell's dry electrode Technology
Tesla can get rid of the additive and Toxic
Solvent used in Today's Battery.
It also gets rid of this drying phase and
calendering process needed to make batteries.
So by removing these expensive and time consuming
steps in the Manufacturing Process
tesla can increase the production rate of
batteries. Also, the cell to pack technology
removes Module assembly and module Testing
steps in manufacturing Process,
which makes Manufacturing Process Way faster.
 So, over time Tesla could boost efficiencies
in all of these  areas to drastically increase
the number of watt hours that a new factory
could produce
Which means Gigafactories can grow, physically
and technologically into becoming Tera Factories.
But Does Tesla Need a Terafactory? ( in the
short term)
Yes, Tesla Needs almost Every Lithium ion
Battery in the world to scale up Production.
Tesla upcoming Roadster, cybertruck and semi
require way more batteries In comparison to
Model 3 or Model y.
 Tesla has had to continuously push back
these projects and the main reason is due
to lack of batteries,
cyber truck  will be a higher volume than
people think
Tesla  has over 600,000 pre-orders for this
vehicle And the number-one competitor Ford
sold 900,000 light trucks in the United States
alone in 2019
so the cyber truck does have a very large
market to go after
additionally about 80% of the cyber truck
pre-orders were for the dual and triple motor
versions
 the tri-motor having 500 miles of range
that's gonna need more kilowatt hours than
a Model y
Tesla roadster on the other hand is an expensive
high-end low volume vehicle which still packs
a 200 kilowatt hour battery that is almost
triple the size of a Model 3.
finally,there's the Tesla semi which has been
delayed to 2021 due to the global health crisis
but
again Tesla doesn't have enough batteries
to produce this thing at scale
the semi will have a 300 mile and 500 mile
version and could have a total weight plus
load of 80,000 pounds
so in order to achieve this range you guessed
it it's going to need a lot of batteries
probably a lot more than even a cybertruck,
if the Tesla uses a megawatt hour or 1000kWh
battery
then a Terra factory would only allow Tesla
to produce a million semis per year and nothing
else
So Tesla may in fact need more Terra factories
Also  Tesla's energy division has been held
back due to a shortage of battery production
at Gigafactories.
It is quite clear that Tesla is Hungry for
more Batteries And a Tera Factory would solve
this for Them.
But even With all this Technologies Breakthroughs
there's one Big Problem Tesla Needs to solve,
Let's talk about the Elephant in the room.
"Raw Materials"
Even if Tesla has the Technology to Produce
A terawatt hour in cell capacity, Lack of
raw materials wouldn't allow them to reach
their full potential.
But there are many Lithium Deposits that can
be mined in the United states and in order
to meet the demand Tesla Has to acquire or
start their own mining company.
Elon Musk's Boring Company would definitely
play a major role if Tesla were to mine lithium
hydroxide
Tesla's plans......
In summary, Tesla will require a Tea Factory
to meet the demand for all of their existing
and upcoming Vehicles along with tesla energy.
Tesla already has the technology to convert
a gigafactory into a Tea Factory and the only
limiting factors are raw materials like lithium,nickel
and so on.
Well, that was it for today's video , if you
are still watching you are awesome! Have a
nice day and I will see you again in the next
one.
