Tesla's Cutting Edge Battery Technology is the secret to Elon musk's Target of selling 20 million
of the electric cars annually by 2030 and just recently he just unveiled another battery that
will shock Toyota what could this be let's find out in today's episode hello everyone welcome
back to Elon Musk Evolution where we bring you the most recent news about Elon Musk and his
multi-billion dollar companies space news and the latest science and technology but before we begin
make sure you subscribe to our Channel and click the Bell icon so you don't miss any of our amazing
videos Elon Musk the CEO of Tesla teased investors with an artist's rendering of a 3.6 billion dollar
expansion of the businesses Flagship Nevada gigafactory last month musk said that Tesla
would quadruple output and cut costs by using a small portion of the floor space currently devoted
to the plant's current Machinery to produce enough batteries to outfit 1.5 million electric vehicles
annually what musk skipped over was that in order to accomplish that enormous efficiency Improvement
Tesla would have to get through a roadblock that has been frustrating the business for more than
two years finding a quicker less expensive and more environmentally friendly way to make EV
electrodes if Tesla could iron out the bugs in the new strategy and incorporate it with
other cost cutting strategies the company might release a mass Market below 25 000 EV recently
there have been some intriguing indications that some businesses are actually moving through with
that strategy dry battery electrode or dbe is a novel technique that battery researchers claim
Tesla is already utilizing for the anodes of some of its most recent batteries furthermore
two businesses claim to be beginning to use the more difficult procedure for producing cathodes
the good news is that Tesla may have the price of the model y battery by employing bigger cells
and a novel method to dry coat electrodes saving more than eight percent of the car's U.S starting
price according to battery researchers with connections to The Firm according to 12 sources
acquainted with Tesla's new technology or close to the company the bad news is that it is just
halfway there the reason for this according to the experts is that the dry coating method used to
make the larger cells in Tesla's 4680 battery is so novel and unproven that the business is having
difficulty scaling up manufacturing to the point where the significant cost savings begin to take
effect one of the Specialists familiar with Tesla claimed that they simply aren't ready for mass
production however the progress Tesla has already achieved in reducing battery production costs over
the previous two years should help increase profitability and widen its advantage over
most of its competitors in the electric vehicle Market investors believe that musk's projected
advancements in battery price and performance are essential to Tesla's mission to usher in a period
in which it can profitably sell an EV for around twenty five thousand dollars and have a better
chance of meeting its 20 30 goals making low-cost high performance battery packs is essential in
creating affordable electric cars that can compete with their combustion engine rivals on sticker
costs because Battery Systems are typically the most expensive components of EVS only a few major
automakers create their own EV batteries and Tesla is one of them by producing the model y cells in
American factories the SUV will continue to be eligible for tax incentives in the U.S even when
many of its competitors May no longer nine of the 12 battery experts are closely connected to Tesla
and three of the nine have disassembled Tesla's new and old Battery Technology to investigate it
from the inside out before the end of this year and possibly not until 2024 the Insiders estimate
that Tesla will struggle to fully integrate the new dry coating production process Elon Musk has
been criticized for being excessively enthusiastic about the timeline for commercializing the novel
method according to Stan Whittingham a co-inventor of Lithium-ion batteries and a 2019 Nobel winner
it will take some time to thoroughly test it but I believe he will find a solution though
perhaps not as quickly as he would want the experts claim that Tesla has only been able
to reduce the price of the model wise battery by two to three thousand dollars so far or roughly
half the savings it had hoped to achieve with the 4680 battery which it introduced two years earlier
but according to them the new 4680 cells which are larger than those in Tesla's current 2170 battery
are the key reason for those savings however the technique of dry coating which musk has
characterized as groundbreaking though challenging to use is at the core of the effort to bring down
prices the sources claim that it should result in as much as half of the fifty five hundred dollars
in cost savings that Tesla aims to achieve through reducing production expenses and one-time Capital
expenditures Tesla obtained the know-how in 2019 when it paid more than 200 million dollars for
Maxwell Technologies a San diego-based firm that makes Ultra capacitors which store energy for
devices that need short bursts of electricity like camera flashes using Maxwell's technology as a
foundation Tesla started producing 4680 dry cells this year first as part of a trial project close
to its facility in Fremont California and more recently at its new Global Headquarters in Austin
Texas Tesla is capable of going away with the older more complicated and expensive wet coating
method thanks to technology it is costly since it requires a sizable amount of electricity equipment
production space time and a sizable Workforce the components are blended with hazardous
binder solvents by battery manufacturers to coat electrodes in the wet process after being coated
the electrodes are baked in sizeable ovens while the Hazardous solvents that evaporate throughout
the process are recovered cleaned and recycled all of which raises the price the Innovative method
eliminates the requirement for drying electrodes by coating them with several binders while using
little liquid accordingly it is less harmful to the environment quicker and cheaper according to
Tesla the procedure is so straightforward that it enables the company to reduce Capital expenditures
by a third as well as the Factory's footprint and energy consumption to just a tenth of what
would be required for the wet process however the sources claim that the company has struggled to
make the procedure profitable Maxwell created its dry coat technique for Ultra capacitors however
coating electrodes for Ev batteries presents a difficulty because they are significantly larger
and thicker making it difficult to do so at high mass production rates while maintaining consistent
quality they are capable of producing in modest quantities but when they began producing in large
quantities one of the persons with connections to Tesla told in a report the Tesla had an
excessive number of rejects The Source claimed that because of the low production yields the
new procedure was unable to save as much money as was projected according to the sources the
production cost for the model wise 4680 battery pack should drop to 5000 to 5500 or about half the
price of the 2170 pack if all the dry coating and larger cell potential efficiencies are realized
these projections however are at risk due to the escalating costs of battery components and energy
and Tesla has not yet been able to considerably increase the new battery's energy density or power
output as musk had projected nevertheless despite these concerns a source indicated that the 4680
battery will ultimately become the industry's best in class for the foreseeable future because of the
savings Tesla is anticipated to realize other enhancements including employing bigger cells
have proven particularly effective according to the experts and account for a large portion
of the two thousand to three thousand dollar cost reduction thus far with the 4680 battery
by volume the size of the 4680 cells is 5.5 times greater than that of the 2170 cells the name comes
from the earlier cylindrical cells which are 21 millimeters in diameter and 70 millimeters tall
the 4680 cells measure 80 millimeters tall and 46 millimeters in diameter according to the sources
using the older technology Tesla needs 4 400 cells to power the model Y and 17 600 welding sites four
per cell to produce a pack that can be fitted into the vehicle Tesla altered the design of the 4680
battery pack such that there are only two weld points per cell reducing the number of welding
to 1660 points and resulting in a sizeable cost savings the 4680 battery pack only requires 830
cells Tesla has been able to further reduce human costs and machine time because of the simplified
design which also results in fewer connectors and other components the much more durable outer shell
of the bigger cell has been another source of efficiency Tesla is now able to use glue
to join the cells into a hard honeycomb-like pack which is then directly attached to the model-wise
inner body structure the source is added that by doing this the intermediate process of bundling
cells into bigger modules before installing them in a conventional battery pack is removed
by switching to this sell to vehicle approach Tesla can cut up to 55 pounds of weight of a
conventional 1200 pound battery pack saving the company between five and six hundred dollars each
pack according to one of the people the Holy Grail though continues to be mastering the dry
coating method bulking up the battery cell greatly improved efficiency however attempting to reduce
the cost of the cell as a whole by 50 percent is a different story according to One Source whether
Tesla can effectively implement the dry coating technique in manufacturing we'll determine that
and now let's dig deeper into what dry Electro technology is in the battery preparation
process dry Electro technology is a Cutting Edge Innovation that is steadily elevating its status
as a primary driver of technical advancement dry electrode is a term used to describe a
method of preparing electrode materials for use in Lithium-ion batteries dry electrodes are made by
directly compacting dry powder electrode materials containing active ingredients rather than through
the conventional procedure of liquid electrolyte infiltration the dry electrode has the following
benefits in comparison to the liquid electrolyte infiltration preparation method greater compaction
density of the active substance in the dry electrode preparation procedure more active
materials can be directly compacted into the electrodes leading to higher active material
compaction densities this is possible since a liquid electrolyte is not necessary this might
boost the electrode's capacity and energy density which would enhance the battery's performance
more stable electrochemistry since a liquid electrolyte is not required during
the manufacturing of the dry electrode it can be avoided that it would cause the electrode material
to corrode and become electrochemically unstable this will increase the cycle life and safety
performance of the battery easier preparation procedure the dry electrode preparation approach
is more straightforward faster and user-friendly than a conventional liquid electrolyte
infiltration preparation method in conclusion the dry electrode preparation method has a number of
benefits the most important of which is that it is capable of achieving a higher active material
compaction density and these can further improve the performance of the battery furthermore the
energy density of the battery may be increased by 20 percent under the same circumstances
process for coating a dry electrode the coding process is a method of applying one or more layers
of liquid to a substrate based on the examination of the fluid's physical characteristics the
substrate is often a flexible film or backing paper and the liquid coating is applied before
being dried or cured in an oven to create a film layer with specific functionality a key factor in
battery performance is the coating thickness which has a direct impact on the electrodes
performance in terms of battery capacity cycle life charge and discharge rate Etc the quality
of the active material and the active area of the electrode surface will both be insufficient
if the coating thickness of the electrode is too thin which will lower the battery's capacity and
discharge capacity on the contrary a thick coating on the electrode will delay the electrolytes rate
of diffusion which will reduce the battery cycle life and rate of charge and discharge
the upper limit of coating thickness for wet electrode coating is typically in the range of
160 microns the electrode structure will become unstable and even develop flaws like bubbles if
the coating layer is too thick which will have an impact on the electrodes performance this
happens during the wet coating process when the coating liquid forms a layer of coating on the
surface of the electrode substrate the coating thickness may be adjusted over a greater range in
dry electrode coating because the coated material is a dry powder dry electrode Coatings typically
have a thickness range of 30 to 5000 microns and Coatings within this range can produce
good electrode structures and great electrode performance but an excessively thick coating
May lower the electrodes transfer efficiency and raise the electrodes internal resistance thus it
is important to carefully monitor the coating thickness during the coating process to get the
optimal electrode performance the capacity of the 4680 battery is over five times greater than that
of the conventional 21700 battery and it has a 46 millimeter diameter and an 80 millimeter height
utilizing ternary Lithium-ion Battery Technology which has a better energy density and cycle life
this battery can store more energy A significant advancement in the realm of battery preparation
for dry electrode technology has surely been made with the release of Tesla's 4680 battery
a 55 premium was paid by Tesla on February 5 2019 to buy the super capacitor company
Maxwell it largely concentrated on Maxwell's distinctive dry electrode technology and had
learned from transitioning to the production process for battery pole pieces to create
technological reserves for following solid-state batteries the study group discovered that the dry
Electro technology was not fully utilized by the 4680 battery in the data collected
during disassembly the cathode does not yet use dry electrode technology due to specific
considerations whereas the anode is the sole part of 4680 to do so the energy density of the 4680 is
still higher than that of the 21700 and 18650 batteries the 4680 battery currently features
a ternary cell with an energy density of 244 to 283 Watt hours per kilogram and the battery
Pack's energy density is 210 Which is higher than the energy densities of the majority of battery
packs on the market right now the new battery design electrolyte and Manufacturing process
advancements of the 4680 battery have all enhanced its performance in terms of energy density and
cycle life even if dry electrode technology has not yet been fully implemented in it
in addition to receiving a lot of attention and research this battery is utilized extensively in
Tesla's electric automobiles and energy storage devices it is expected that the upcoming years
of the battery industry will be brighter and more sustainable as a result of the ongoing
promotion and advancement of dry electrode technology in the field of battery preparation
key battery performance characteristics such as energy density and cycle life will be more
optimized in addition to marking a significant advancement in Battery Technology Tesla's use of
dry electrodes has given energy storage and the development of electric vehicles fresh life and
momentum a significant factor in getting extended range and quick recharge in sectors like electric
vehicles is higher energy density as a result the use of dry electrode technology will open up more
opportunities and space for the development of electric vehicles energy storage and other
industries of course dry electrode technology is not Flawless and the needs for battery preparation
methods and tools are fairly High necessitating more expert technical assistance and refine
preparation but as Science and Technology continue to advance and develop more and more applications
of dry electrode technology will be made which will Spur new Innovations in technology and open
up new economic opportunities for the battery sector foreign meanwhile no matter what brand you
choose you can now receive the maximum tax credit of seventy five hundred dollars if you purchase
a Tesla Model 3 in the US Tesla has changed its website to reflect that the rear-wheel drive model
3 and its long range and performance counterparts now qualify for the full federal tax credit for
EVS if you choose the all-wheel long range or performance model y you'll also get to take
advantage of the same savings in order to comply with the provisions of the inflation reduction
act which the president signed last year the U.S government released a revised set of guidelines in
March for which electric vehicles are eligible for the federal 7 500 EV tax credit according to the
new regulations which became effective on April 18th Vehicles using battery components that are
built or assembled in the US to a minimum of 50 percent are eligible for a thirty seven hundred
fifty dollar tax credit according to the filing the dojacoin price soared thirty six thousand
percent over the course of two years before falling down amid a wider crypto Market sell-off
