Tesla's Battery (future technology )
# Samsung's grapheneb attery promising five times fasterc harging coming to phones as early as 2022 recent battery research breakthroughs - an exclusive interview
with an industry expert in battery
recycling in all of this the company
that has come up the most is Tesla love
them or hate them they were the pioneers of the latest iteration of the electric car they forced innovation from industry old guards like Porsche and Jaguar which is great this isn't to mention their batteries used in industrial settings such as balancing power grids Elon Musk last year claimed something especially outlandish a new battery that could last for over a million miles critics thought it was impossible.
Elam claimed that Tesla would soon have a battery that can last for a million
miles or about 1.6 million kilometers
the current battery pack is about maybe
300 to 500 thousand miles of the new
battery pack prolly going to production
next year is designed explicitly for a
million miles of operation the entire
vehicle battery pack occlusive it is
designed to operate for a million miles
with minimal maintenance maintenance
after this amount of use it will still
have over 90 percent battery health
remaining to put that into context
that's two times the current lifespan of
Tesla's contemporary batteries we'll get
to the details of the battery in a second but Eva's claimed this could put electric cars in general in an interesting position.
according to NBC news a regular petrol
car lasts for about 150,000 to 300,000
miles before something breaks that makes it not worth repairing when you thinkabout it a regular petrol powered car is actually pretty complicated it needs regular maintenance to keep it
operational and it's unavoidable that
some parts just wear out after a given
amount of time problems like a slipping
automatic gearbox or a blown head gasket can be expensive to repair and can take a car off the road permanently electric cars are much simpler with the only major moving parts being the electric motor and usually a single speed transmission with these new batteries this all means electric cars could last longer than their petrol counterparts it goes further than this though as you've previously seen in the battery recycling episode rub the industry expert I interviewed for the piece stated that electric vehicle batteries have much more life after being used up in the car they can then be used in power management to support a grid and after that lower and lower power consumption requirements until they can finally be recycled with a battery with twice the state-of-the-art lifespan this opens up a whole new world of opportunities ok so let's take a look at the battery itself a physicist by the name of Jeff Don led the research of the new battery which was vastly superior to any other lithium-ion battery previously seen Jeff is already a leading expert in lithium-ion research him and his team at the owl house eat University has an exclusive licensing agreement with Tesla this suggests that this technology could appear in the company's cars the details of the paper are pretty extensive it includes the full cell design including electrode compositions electrolyte mixture additives and more the team's results show that these batteries can be charged and depleted more than four
thousand times and after this they only
lose 10% of the original energy capacity
to put this into perspective a 2014
paper showed that similar lithium-ion
batteries lost half their capacity after
only a thousand cycles according to the study headed by Jeff which was published in September 2019 the 1 million mile figure is equivalent to two decades of in grid energy storage what's interesting though is that the authors of the paper don't Herald this all as a new
breakthrough they present it as a benchmark for other battery researchers
this is the opposite to common practice
usually battery designs are often a
closely guarded secret within the evie
industry providing this information to
everyone aims to help other companies
improve their own designs for the future
he is acquired by the authors of the
paper quote full details of the cells
including electrode compositions
electrode loadings electrolyte compositions additives etc have been
provided this has been done so that
others can recreate these cells and use them as benchmarks for their own R
efforts end quote I think this is great
news this research was done to further
the progress of battery technology not
just for one group but as a whole for
everyone and I think that's a noble goal
generally speaking there's usually atrade-off between energy density and
battery lifetime if you want more of one
you get less of the other Jeff's group
was responsible for doing the seemingly impossible they overcame this trade-off now you can have increased energy density and battery life interestingly the materials used in the paper aren't you the huge performance boost was achieved through a great deal of optimizing already common battery ingredients they also tweaked the nano structure of the batteries cathode to increase performance the new nano structure is less likely to develop cracks when the battery is charging cracks in the cathode material caused a decrease in the lifetime and performance of the battery and this happens during repeated charging cycles basically the new cathode and this new battery will be able to resist more wear over time Jeff Don estimates that most Eevee users is only about a quarter of a charge per day but to make something like a fleet of Robo taxis or an empire of long-haul electric trucks Tesla would need a battery that can handle full discharge cycles each day this could really make electric long-range or long-term transport of many kinds much more feasible so with so many stories of battery research rapidly coming forward it seems like we're at the start of a new age an age different from the previous decade where battery technology stayed stagnant if you do want to see my
previous battery room videos including
the state of better recycling I'll leave
a link to my battery playlist below and
just a quick update while making this
video some other battery news just broke researchers at the University of
illinois-chicago have made a new carbon dioxide battery that holds seven times more charge than current lithium ion methods that published their findings in the journal of advanced materials so if this video does well and you do want to see a video about this new tech I'll be sure to make it so thanks for watching I really appreciate it.
Tesla the future of battery
