Elon Musk made a promise and Jeff Dawn kept it Tesla May soon have a battery that makes their
robot taxis and long-haul electric trucks possible according to Don who disclosed this to the world
with the publication of a groundbreaking work in the Journal of the electrochemical
society and that is what Elon Musk dubbed as the million mile battery with at least 10
000 discharge Cycles but what do we have a forever battery with 200 000 discharge
cycles that would be awesome right let's check it out 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

as a partner in battery research Don and his team work with Tesla people that are interested
in Tesla are probably familiar with Jeff Don he has been a research collaborator with Tesla since
2016 and teachers at Dalhousie University he is concentrated on making Lithium-ion batteries
more affordable while also extending their lifespan and increasing their energy density
two years ago the idea of a million mile battery a remarkably durable lithium-ion battery that could
survive decades while driving an electric vehicle over large distances and costing roughly the same
as a regular battery caused a stir when Tesla and General Motors later indicated they were close to
actually creating such a battery the Uproar that was initially caused by a report co-written by
Jeff Don a professor at Dalhousie University and chief battery scientist for Tesla gained
additional traction Tesla's patent Dawn aspires to develop batteries that are never disposed of
in the recycling they would transfer to another vehicle act as a standby power source in buildings
and factories or participate in vehicle-to-grid services that store and Supply electricity during
times of peak demand for electric utilities among other Second Life uses given that the full battery
would still be in use and not just a small portion of it would contain recycled Metals this strategy
might significantly minimize the mining of battery metals and minerals Dawn informative's online
audience that he didn't think 1000 cycle batteries were ideal for the environment Dawn reported using
a reliable nickel manganese Cobalt battery known as the nmc 532 in conjunction with a very good
artificial graphite anode to get there he focused a lot on electrolyte additives which would employ
compounds like methyl acetate to allow the battery to charge quickly without harming it
the electrolyte is the liquid that separates the two electrodes the use of big single crystals for
the cathode rather than the more typical smaller polycrystalline particles was also mentioned by
him single crystals he claimed are significantly less prone to microcracking a bane of Lifetime
as lithium ions move in and out of the electrodes the electrodes expand and contract which causes
micro cracking the relatively strong nature of single crystals but prevents them from breaking
according to Dawn's Dalhousie lab their experimental battery cell has now undergone 13 000
Cycles which would enable a car to travel between 3.2 and 3.7 million miles while maintaining an
astounding 93 percent of its initial capacity depending on how many miles were traveled each
year however only if the battery is kept in a room with a temperature of about 20 degrees
Celsius Dawn cells have functioned well lasting 6 500 cycles and keeping more than 80 percent
of their initial capacity even at the harsher but more realistic temperatures of 40 degrees Celsius
Tesla patented the million mile battery developed by Dawn two years ago and Elon Musk the company's
CEO promised to use the durable battery in 2020. musk didn't carry out his Ambitions during that
year which has since passed for instance on Tesla battery day in September of last year
he omitted to mention the million mile battery when Tesla's battery with a million miles will
be accessible is the major issue a precise time frame hasn't been provided by Tesla it
may be a few more years before the battery is prepared for Mass manufacturing according to
the company which has stated that it is still trying to perfect it musk surprised attendees
at the ceremony by saying that the test project might be put into commercial production by 2030.
there is still a ton of work to be done he noted we're not saying this is completely in the bag
but the idea of a million mile battery shows a lot of Promise despite expectations the public
release of the million mile battery in 2023 was not possible there is no news on when Tesla
intends to deliver this million mile battery although it is thought that they are working
on it right now if anyone can achieve it Tesla can so we'll have to wait and see if they succeed
an Innovative idea dubbed the million-mile battery has the potential to fundamentally alter how we
currently think about how much energy we use there is little doubt that Tesla will be able to fulfill
This Promise despite the fact that it may appear to be an unattainable objective given its history
of innovation and Brilliance let's hope they can reach this significant Milestone so that we can
all take advantage of the improved efficiency and lower battery costs that a million mile battery
would offer let's hope for the best while waiting for the million mile battery Elon Musk just
leaked another groundbreaking battery that will outperform the million mile battery but before we
dive into that let's check first how many miles can a Tesla go in its lifetime Tesla automobiles
are long lasting Elon Musk claims that you should anticipate the same battery to last between 300
000 and 500 000 miles or a lifespan of 22 to 37 years how quickly a battery deteriorates or loses
capacity is influenced by two factors one how many times the battery was used and recharged and two
the time since the battery's creation of course a Tesla's lifetime mileage will differ based on a
number of factors your driving style the roads you use and even the weather can all have an
impact on how long your Tesla lasts however if you take good care of and maintain your Tesla
it should be able to travel far the Tesla's miles vary depending on the type of vehicle you drive
the next step in battery Evolution nanowire batteries current battery technologies cannot
match the longer life of a novel nanowire battery chemistry it has taken a long time and much effort
to create the ideal battery can Lithium-ion batteries be replaced by nanowire technology
as the industry standard though they have more complicated charging requirements Lithium-ion
batteries can occupy the top spot in terms of their capacity to store a lot of energy per weight
Lithium-ion batteries aren't perfect but they're close to being found in all modern portable
Electronics nanowires however may eventually overtake Lithium-ion batteries in popularity
nanowires are incredibly tiny wires with a diameter of just a few nanometers and
because of their size they have a direct connection to quantum physics
what is a nanowire nanowires also refer to as Quantum wires are exceedingly thin wires with
a thickness of just a few nanometers the consequences of quantum mechanics apply to
them since they are so minuscule the properties of nanowires have so far been shown to vary depending
on the elements and compounds from which they are made there are molecular nanowires superconducting
nanowires made of Atrium barium copper oxide metallic nanowires made of nickel platinum or
gold semiconducting nanowires made of silicone or other compounds insulating nanowires made of
silicone or titanium dioxide and metallic nanowires made of nickel platinum or gold
up until recently molecular nanowires were thought to lack the characteristics that would make them
useful in electronics and our understanding of the formation of certain nanowire compounds was hazy
at best researchers have made progress toward their goal of creating semiconductor nanowires
with the compositions and architectures of their choice for years scientists have been aware of
how nanowires arise but they have never been able to watch the phenomena clearly enough to
control its development the ability to conduct chemistry experiments at the atomic level has
been granted to the researchers in Lund who may now experiment with the growth of the nanowires
by exposing them to various elements to see the outcomes in a piece4nature.com research engineer
Daniel Jacobson from Lund University expanded on this finding we now have on taped the events
that take place and what is required to be able to control the nanowire growth researchers at
UC Irvine developed a battery that used gold nanowires and had a charge storage efficiency
of 94 to 96 percent and was capable of 200 000 discharge Cycles Lithium-ion batteries normally
only endure for 500 plus charge cycles thus this is unprecedented how do they work due to the small
size of nanowires Greater surface area can be achieved in a smaller volume more charge can then
be stored as a result of this cycle stability or the disintegration of the nanowires when they are
repeatedly charged is a problem with nanowires it should be clarified that since this is by no means
close to a finished product phase these tests were conducted without positive and negative terminals
an anode and a cathode the battery developed Bears little resemblance to a battery because it
only contains two cathodes which is better for measuring the charge cycles because they were
connected together in this discharge Cycle One cathode is charged the other discharged and so on
the forever battery Are We There Yet because they promise to outlast conventional technologies that
rely on the electrochemical discharge of ionic Solutions solid-state batteries are sometimes
referred to as forever batteries in the context of Battery Technology
over time those Solutions lose charge capacity and require more frequent charging Lithium-ion
batteries breathe during charge and discharge Cycles which exerts stress on battery connections
and heat sinks during charging the end consequence is a battery whose capacity starts to decline and
whose performance starts to decline very quickly that is not the case with ssbs which remain to be
the Pinnacle of Battery Technology if implemented ssbs could totally upset current battery
technologies and all the devices that have come to depend on lie ion SSB vs lie ion Technologies
electric current is produced by the flow of ions between the cathode and anode through an ionic
conducting material known as an electrolyte the mechanism for producing electricity in ssbs and
lie ion batteries is the same the main distinction between solid-state batteries and conventional
batteries is that ssbs employ solid electrolytes manufactured from glass Ceramics solid polymers or
sulfides while lie ion devices use liquid or polymer gel electrolytes another distinction
between the two battery technologies is the presence of a separator between the cathode and
anode in lie Ion systems an electron insulator called a separator which also functions as a
permeable membrane to ensure that only ions can flow between the anode and the cathode prevents
short-circuiting although a solid electrolyte does not necessitate the use of a separator the LIE ion
separator materials are being applied to the solid electrolytes interfaces in ssps to reduce dendrite
formation one of the most difficult technical problems in the development of ssbs has been
dendrites which are tiny lye metal growths that can puncture battery interfaces and lead
to electrolyte failures energy density measures how much energy a battery has in relation to its
size and weight because ssbs offer a higher energy density due to the space-saving benefits of solid
electrolytes more compact batteries with longer life cycles and faster charging can be created
the materials used in both types of batteries vary depending on the manufacturer as a result
of advances in Battery Technology batteries with chemistries like lithium Cobalt nickel
Cobalt nickel manganese Cobalt or lithium iron phosphate are frequently used as cathodes in both
Technologies an essential component of electric vehicle Battery Technology for manufacturers who
want to continue with conventional battery technology is graphite or carbon which is
typically used to make lie ion battery anodes the fact that ssbs don't employ combustible elements
allows them to run at higher temperatures than traditional batteries due to the fact
that the batteries don't overheat this benefit also supports quicker charging in addition the
performance of the battery is decreased because a solid electrolyte doesn't freeze up like a liquid
electrolyte can Japanese researchers are working on live free solid-state EV batteries that employ
manganese ions in place of the lie that ssbs may use which can use up to 35 percent more lye than
lie ion batteries the big challenges facing ssbs why have ssbs not being more common researchers
working on batteries must first overcome a few technical challenges creating lithium dendrites
which are asymmetrical lie growths that extend from the anode into the cathode material has
proven to be one of the most difficult tasks this causes conductivity inefficiencies may
cause the electrochemical materials to crack and in some situations can result in thermal Runaway
this problem has been addressed by researchers by avoiding the use of lithium experimenting
with various separator types running ssbs at high temperatures or toughening the cathode
this naturally results in high manufacturing costs for ssbs which are still a unique and archetypal
technology that are not yet in mass production vacuum deposition equipment is also needed for
ssbs and it is both slow and inexpensive along the anode and cathode interface there are additional
difficulties the surface area between the materials can occasionally be passivated by
byproducts of electrochemical reactions raising resistance and lowering performance ssbs are
also susceptible to the breathing that lie ion liquid electrolytes need to do first of all this
exerts mechanical strain on the connections and electrodes which if harmed can damage battery
performance and possibly safety this issue in lie ion batteries can occasionally be resolved by
spring or foam substance that exerts consistent pressure against the connectors with solid state
materials which demand even higher pressures this has proven more challenging to deal for
big Investments none of these difficulties are thought to be insurmountable at least not when
compared to the opportunities and wealth that comes with a novel disruptive battery type
although SSB have the potential to improve upon the drawbacks of traditional lie ion
batteries a business by the name of quantum scape asserts that most of the issues related
with their construction have been resolved this is especially true in the multi-billion dollar
EV sector where ssbs have not yet been widely accepted in addition to a 300 million dollar
investment from VW the company's share price is soaring however the business has also had
to deal with legal issues with allegedly false statements made regarding their SSB technology
the forever battery from quantumscape is neither the first nor the only product of its
sort numerous automakers are quietly conducting their own r d into forever Battery Technology
for the EV industry including Toyota Nissan and Chevrolet the advancement of NASA's SSB
technology is ongoing as well While others such as Dyson Fisker and Tesla have chosen to concentrate
on enhancing the performance of typical lie ion batteries however quantumscape is not the only
game if manufacturers can figure out the proper formula ssbs will be more advantageous than lie
Ion systems in terms of size charging speed safety pollution reduction speed of production longevity
and range but there are several difficulties in translating laboratory breakthroughs in
new Battery Technology into real-world useful applications applications for ssbs
The Battery Technology now preferred for use in EVs and for industrial electrification lie
ion batteries are being replaced by ssbs in a competition for market share fin ssbs are ideal
for powering relatively small scale applications and processes such as Internet of Things devices
Smart Home Appliances medical equipment like pacemakers wearables computer components
energy harvesting devices and sensors in smart environments and Manufacturing automation systems
