in our last episode we talked about what could be the lowest price tv in the us with the starting
price that's expected to start from 25 000 these economically priced entry-level evs will surely
play a key role in hyundai's plan to become a dominant force in the eevee world in its
mission to sell 1.7 million evs by the year 2026 on their way to becoming an exclusive ev maker
and become completely carbon neutral by 2045 however as enticing as low price tvs that would
have to sacrifice the range and the performance consumers continue to demand longer driving
more sophisticated evs and hyundai has an answer to the growing number of people that are becoming
more demanding of the evs that they purchase in this episode of auto vision we will explore
all the efforts that the hyundai motor group is putting forth to deliver longer driving
technology to complement its benchmark ultrafast 800 volt charging technology

the question that's presented at the end of the video it's not a secret that the ultimate goal
of every ev manufacturer in the world is to reach the elusive 500 miles or 800 kilometers in range
this is not because people actually have a need to drive 500 miles in a single excursion but because
of what's known as range anxiety ev range anxiety is the fear of running out of power on a journey
and not being able to find a charging point it's a major stumbling block to greater ev adoption
and it has more to do with psychology than the actual range of evs or the availability
of charging points psychological or not it's a milestone that all ev manufacturers are trying
to achieve from the marketing standpoint however from the standpoint of engineering it's a figure
that's also not easy to achieve by the current level of battery technology the lithium ion
battery is the current top echelon technology that typically has an energy density of 300 to 350 watt
hours per kilogram which typically translates to 500 to 600 kilometers in range for this reason a
new class of technology must be utilized in order to extend the range to 800 kilometers
and most people in the industry would agree that a solid-state battery is a solution to this problem
unlike lithium-ion batteries solid-state batteries do not contain heavy liquid electrolytes
instead a solid electrolyte is used that can be in the form of glass ceramics or other solid
materials without the need for a liquid solid state batteries can be much denser and compact
translating in more range also solid state batteries are much safer than conventional
lithium ion batteries which use organic liquid electrolytes that are flammable and volatile
solid state batteries charge much faster as well as they can reach an 80 charge within 15 minutes
and incur less strain after multiple charging cycles a lithium-ion battery will begin to degrade
and lose power capacity after 1000 cycles on the other hand a solid-state battery will maintain
90 of its capacity well after 5000 cycles and even up to high as 10 000 cycles however many obstacles
lie ahead before the commercialization for the use in evs can be realized
first scaling up production to the level needed for usage in evs remains an expensive endeavor
solid-state batteries are nothing new as the concept was invented in the 19th century
and its claim to fame is a smartwatch and a heartbeat regulator until now
solid-state batteries are traditionally expensive to make and employ manufacturing process is
thought to be difficult to scale requiring expensive equipment to produce one example is
vacuum deposition equipment which deposit layers of material atom by atom or molecule by molecule
on a solid surface to alleviate the problem associated with its inherent flaw in its chemistry
which is that it can potentially degrade fast after a number of charge discharge cycles
due to the accumulation of lithium dendrites thin tree-like pieces of lithium that branch out
and can pierce the battery thereby causing short circuits and other problems rendering the battery
unusable as the lithium metal anode is compromised however the use of multi-layer design employs the
structure that places a less stable electrolyte sandwiched between more stable solid electrolytes
which prevents any lithium dendrite growth making them multi-layer solid-state batteries
hold 82 percent of their charge after 10 000 cycles which is competitive with the lifetime
of a fossil fuel-powered car however there are still many problems to be addressed such
as low-temperature operations as solid state batteries historically have poor performance
as well solid-state batteries are prone to breakage as ceramic electrolytes require
high pressure to maintain contact with the electrodes and may break from mechanical stress
for all these reasons commercialization is still years away and the experts predict that it will
be 20 30 before it can be realized the good news is however there is a stop gap measure that may
bridge the gap between the traditional lithium battery and the solid state battery and that is
the lithium metal battery which is a hybrid of the traditional lithium-ion and solid-state battery
hyundai has invested 100 million dollars in ses which is a spin-off of mit based in singapore
originally called solid energy systems it changed its name because it decided that the production
of 100 solid-state batteries wasn't practical due to the problems as explained previously
instead the company has pivoted to a hybrid battery which means it combines solid and
liquid components specifically a protective anode polymer coating with a proprietary
highly concentrated solvent in salt liquid electrolyte
this is because while solid electrolytes are best at preventing dendrite formation they have their
own flaws which is manufacturability as mentioned earlier despite using the liquid electrolytes scs
claims that its anode has an energy density of 417 watt hours per kilogram with a capacity of 107 amp
hours at room temperature while capable of charging 10 to 90 in just 12 minutes
this means the hybrid battery is near solid state and can achieve the elusive 800 kilometer or
500 mile range which is a huge breakthrough in cooperation with the compatriot lg and sk that
is also invested in the company it's expected that the full commercialization of the hybrid
lithium metal battery would be ready by 2025 with a production capacity of one gigawatt hour just
in time for the massive demand for batteries that would be required to meet hyundai's sales target
the first hyundai models to receive the newest lithium metal battery is the next generation
genesis model in the high-end hyundai and kia evs such as the gv90 electric suv that is to share the
large egmp platform used on the production models based on the kia concept ev9 and the hyundai
7 concept which is expected to have the battery capacity of 100 kilowatt hours it will also power
the next generation g80 and gv80 models which will be converted to pure evs based on genesis
first proprietary electric platform instead of borrowing the egmp platform the re mac derived
genesis platform uses a t-shaped battery and will be used on the next generation genesis evs because
egmp has a limitation of 600 horsepower and forces high vehicle height due to placement of
battery on the floor not ideal for sleep low slung sedans and coupes that genesis hopes to produce
the expected release date of the all-new g80 and gv80 evs will be in 2025 as genesis is ceasing ice
products starting in 2025. the 800 kilometers or 500 mile range batteries would eventually
trickle down to more mass-market products like the ionic 5 and the kia ev6 as well eventually
however the hybrid lithium metal battery is not without a shortcoming as it has a rather
short lifetime it can only offer 70 percent performance retention after 779 cycles and 90
retention in 550 cycles compared to a conventional lithium ion batteries 1000 discharge cycles
this can be justified as the per charge energy density is greater but it's a far cry from the
full solid state battery that has a lifespan of up to ten thousand cycles as mentioned previously
that's the reason why hyundai is also investing in massachusetts-based startup factorial energy
which claims its solid-state battery technology is safer than conventional lithium-ion technology
extends driving range by 20-50 and is drop-in compatible for easy integration into existing
lithium-ion battery manufacturing infrastructure the company has also known to have solved the
solid-state battery's inherent problem of not holding the capacity at room temperature by its
proprietary solid electrolyte to create cells with high voltage and high-capacity electrodes
that enable a 40 amp hour solid-state battery cell for evs that works at room temperature
this is in addition to the investment the hyundai has already made in conjunction with
sk innovation back in 2018 to acquire 4.26 of colorado-based solid power to produce
all solid-state batteries that use the existing ncm or nickel cobalt manganese cathode materials
used in lithium-ion batteries and high content silicon anode material the resulting product
would realize a target energy density of 930 watt hours per liter or higher which
is approximately 33 percent higher performance than that of the current lithium ion battery
hyundai hopes that a prototype of the full solid state battery is also introduced by 2025 and be
ready for commercialization by 2030. finally hyundai is partnering with ionq a leader in
trapped eye on quantum computing to create better quality batteries by more precisely simulating
and controlling their chemical reactions this research has the potential to lead to new types
of source material that save time cost and effort in the years to come quantum powered chemistry
simulation is expected to significantly enhance the quality of next generation lithium batteries
by making improvements to the devices charge and discharge cycles as well as their durability
capacity and safety so in summary hyundai's effort seems relentless in its pursuit to become a leader
in evs with a series of investments made towards improving the range of its electric vehicles
that would complement while its 800 volt ultra fast charging platform that seems
to be miles ahead of the competitors as for the end of the video question which of the
hyundai model would benefit most from hyundai's upcoming 800 kilometer or 500 mile range battery
