[Applause] the advancement of Battery Technology is the new Bullseye for companies striving to meet the world's growing appetite for EVS with a focus in battery life which is currently still one of the top concerns for electric car buyers because the long-term operation of EVS depends mainly on the battery however scientists have figured out how to make a battery last up to 200 years and could completely change the electric vehicle battery industry so stay tuned to find out more but before we begin please show your support by subscribing to our Channel and ringing the bell so you won't miss out on any of our interesting videos in the future now without any further delays let's get started with today's episode two years ago a sensation of Doubt arose around the notion of a million mile battery an extraordinarily durable lithium-ion battery that could last decades while powering an electric vehicle over long distances and costing more or less the same as an ordinary battery a million mile battery is equivalent to around 70 years of battery life Jeff Dunn a Dalhousie University professor and lead battery scientist for Tesla was also interested in this concept and gained more traction at the time when Tesla later said they were on the verge of actually producing such a battery but just as soon as it gained traction it was gradually forgotten it turns out however that those leading battery researchers have quietly continued to develop batteries that last 1 million miles or longer accordingly Tesla battery researchers with Professor Jeff Don have presented updated test results for their battery cells instead of 1 million miles the batteries are now expected to last 10 000 cycles and provide traction power for more than 2 million miles that's about 3. 5 million kilometers which is similar to around 200 years of battery life Jeff Don explained the results from his work on particularly durable battery cells accordingly to get there Don described pairing a very good artificial graphite anode with a nickel manganese Cobalt battery called nmc532 Don also shared with special additives particularly the liquid separating the two electrodes which would use chemicals such as methyl acetate to allow the battery to charge fast while not damaging it the batteries should be able to withstand 10 000 Cycles assuming a relatively conservative 350 kilometer range per cycle for example a full charge from zero to one hundred percent this would be 3. 5 million kilometers hence this number clearly surpassed the 1 million miles that were announced before 3.
5 million kilometers or 2 million whichever one you like it's still a big deal because now the lifestyle cycle for electric vehicle batteries is currently limited to hundreds of thousands of miles Tesla is still offering a minimum 70 percent battery retention guarantee over a period of eight years or 120 000 miles the Chevy Bolts from GM has a standard eight years 100 000 mile warranty for its battery as well according to Professor Jeff Dunn if the cells were treated more carefully specifically if the complete charge stroke from zero to a hundred percent was not used the cells could even last 15 000 Cycles in fact graphs published by a source show a much more constant cell capacity over ten thousand Cycles with a charge stroke from zero to eighty percent then with a charge stroke of zero to ninety or zero to one hundred percent if the batteries were only discharged by 25 to 50 percent of their capacity they would show almost no degradation this is a charge level range that many electric car drivers use in practice the battery is rarely discharged to less than 20 percent on the other hand it's rarely charged over 80 percent Don's Dalhousie lab reports that it has now cycled its experimental battery cell 13 000 times which would allow a vehicle to travel 3. 2 million to 3. 7 million miles depending on how many miles were driven per year while retaining an astonishing 93 percent of its initial capacity but that's only if the battery stays at room temperatures of around 20 degrees Celsius or 68 degrees Fahrenheit add more punishing but realistic temperatures of 40 degrees Celsius or 104 degrees Fahrenheit Dons cells have performed less as well but still stoutly lasting 6500 cycles and retaining more than 80 percent of their initial capacity in view of such range and degradation figures Don himself raises the question of whether batteries are needed that are this good he quickly answers his question with yes for one thing such durable batteries would not have to be recycled after use he claims since they are as good as new they could simply be installed in a new car after use in the first car after it has been scrapped on the other hand they could be used in vehicles with higher requirements such as commercial vehicles and electric Ferries in addition 3.
5 million mile batteries or 200 year life batteries that do not suffer from frequent charge discharge Cycles could also be better integrated into the power grid and stabilize the grid not only as stationary storage devices but also in the vehicle in order to nevertheless be able to store power in vehicles the development of vehicle to Grid or v2g applications is inevitable in Jeff Don's vision of the future electric cars double as renewable energy storage devices he said you have to be able to store renewable energy for when the wind isn't blowing and the sun isn't shining equipped with long lifetime million mile batteries electric cars of the future will be brimming with unused energy when the car is parked and night has fallen excess energy can be redirected back into the grid to power homes buildings and anything else connected to the grid cars will no longer just consume energy but could also be a valuable source of energy this process of vehicle to grid energy is something Jeff Dunn is really excited about in order for this to work the batteries need to be extremely powerful that's why he's hoping to finalize a battery that can last several thousand charging Cycles several experts said that vehicle to grid sounds great but it'll require buy-in from energy companies car manufacturers and governments it will also require smart technology and vehicle grid integration in other words charging stations will need to be bi-directional in order to push and pull electricity between the cars and the electric grid on the other hand Tesla was rather reserved on the subject of bi-directional charging with reference to battery life however some sources revealed that Tesla Was preparing a bi-directional charging function later on furthermore most likely in the near future Tesla's team of battery scientists and experts will quickly develop and apply million mile batteries for its models it will be one of Tesla's most terrific Battery Technology breakthroughs ultimately has any electric vehicle company applied this million mile Battery Technology in China byd and catl the battery Giants are each advertising an electric vehicle battery life of 750 000 to 1 million miles which is equivalent to five to seven decades of average driving meanwhile in the west AGM spokesman said that the company's ultium battery which will will be used in its electric cars will last a million miles or 1. 6 million kilometers as well they also promised its ultim battery would be cheaper and more efficient than any other conventional battery according to a report there will be more than 300 million electric vehicles on the road worldwide by 2030. it's only seven years away so if we're to add 280 million vehicles in seven years we'll need a lot of batteries made using cheaper and more abundant materials this is why scientists at Drxel were looking into a brand new type of battery that's cheap with the price of 17 dollars per kilowatt hour known as lithium sulfur so why does this lithium sulfur Discovery make it the future of battery storage over the last few years lithium sulfur batteries have been touted as a strong candidate for marking a new energy storage era but they haven't made it to the market yet now a group of chemical Engineers from Drxel University has found a way to enable their real world application through the utilization of sulfur because you can keep the sulfur on the cathode side it protects the lithium electrode introducing sulfur into a lithium battery has been difficult due to what the researchers describe as an irreversible chemical reaction between intermediate sulfur products this has resulted in nearly immediate shutdown and complete failure of the battery after just one cycle thus the research team at Drxel were looking at ways to redesign the battery's cathode in order to prevent the damaging chemical reactions that take place during the charging process but what they discovered instead was a rare chemical phase of sulfur that prevents the reaction the result shows that this battery actually performed amazingly well how much will a lithium sulfur battery cost in a world where commodity prices for battery materials are going crazy switching to lithium sulfur isn't just a good idea it's an incredibly sensible 1.
being the 10th most abundant element on Earth sulfur is much easier to find than Cobalt and nickel plus it's obtained as a byproduct of various industrial processes such as petroleum refining sulfur's price has also risen over the last 12 months by 47 percent however the cost of sulfur is dirt cheap currently 382 dollars per metric ton to make the comparison you can purchase nearly 200 tons of sulfur for what you pay to get one ton of cobalt the researchers say they have optimized production costs so that the lithium sulfur battery costs six times less than Tesla's current 4680 battery again that's about 17 dollars per kilowatt hour that's why introducing sulfur into the cathode formulation would relieve pressure on the EV supply chain and could reduce the costs of EVS how does a lithium sulfur battery's energy density outperform that of a Lithium-Ion battery according to the research a 4680 cells energy density was 244 Watt hours per kilogram in contrast the energy density of the sulfur battery will be around 723 Watt hours per kilogram what does that actually mean in practice well for instance if you were to swap your EV lithium-ion battery with a lithium sulfur one you could drive your car roughly three times longer without needing a recharging station or you could keep your existing range with a much smaller lighter and cheaper battery pack today's top performing EVS using Lithium-ion batteries have ranges that top out around 500 miles with a lithium sulfur battery now a car with a battery that weighs exactly the same could travel up to 1500 miles on a single charge how long does it take to charge the lithium sulfur battery these new batteries have the advantage that they can retain 91 percent of their capacity after 1700 cycles of fast charging at a rate of 2C which is fully charged and discharged in 30 minutes the researchers add that the these batteries can still hold 74 percent of their initial capacity even after a thousand Cycles at 5C which go from fully charged to fully empty in 12 and a half minutes what does the C mean exactly the C rate is the unit battery experts used to measure the speed at which a battery is fully charged or discharged for example charging at a c rate of 1C means that the battery is charged from zero to one hundred percent in one hour for comparison 4680 batteries are made to keep at least 80 percent of their initial capacity for a significant number of charge cycles and they fully charge in 52 minutes so then what breakthroughs have scientists made on the lifespan of lithium sulfur batteries despite the mystery after a year of testing Drcholera and her co-workers proved their sulfur cathode stabilization over 4 000 charged discharge Cycles meaning it lasts at least twice as long as lithium ion which is about 50 years where will this battery be be applied lithium sulfur batteries are also lighter making them highly attractive for drones and electric planes in fact in 2020 LG Energy Solutions installed a lithium sulfur battery in a high altitude long endurance solar powered unmanned aerial vehicle developed by the Korea Aerospace Research Institute it successfully performed well in a test flight at the highest altitude possible in the stratosphere for 13 hours but besides that a significant agreement by Australian company Lis energy Inked in 2022 was with leading us e-aviation company magnix which will test the potential of the lithium sulfur cell technology for e-aviation applications in short lithium sulfur batteries could allow a huge range of activities to go electric such as short haul flights cargo vessels and passenger ferries the weight saving long life and competitive price will mean these sectors can finally achieve their low carbon goals still this sounds like a lot of work how long long is it going to take for this battery to get out onto the market we've been talking to a lot of Industry folks to get an understanding of the steps Beyond where we are right now and our understanding of such a technology would be more in the range of five to six years Drxel's Viva cholera highlighted some possible use cases but we believe this is much sooner than five years but that isn't the end of this discovery the team at Drxel is currently looking into using this breakthrough to make sodium sulfur batteries by removing the need for lithium they can make batteries even more eco-friendly and eliminate a massive supply chain bottleneck ensuring EV adoption can continue at the Breakneck speeds car makers are planning for now will musk invest in this lucrative project while Ford and Mercedes-Benz have Partnerships with battery manufacturers to explore solid-state technology Elon Musk is planning to add lithium sulfur batteries to expand the range of Tesla vehicles this partnership with the Drxel team starts in 2023 this year and is supposed to blow up the EV Indus history Drxel's unexpected yet radical achievement may be finally pulling the sought after lithium sulfur battery within commercial reach with lower cost higher power density and greater durability this technology would change the way we think about energy storage for good having said that scientists will still need to prove their optimized device outside of the lab so our cars smartphones and drones will have to wait a little longer before being supercharged to the next level how do you feel about the future of lithium sulfur batteries do you believe as kaura said that they will be released sooner than five years let me know your thoughts in the comments section down below uh which is that graphene aluminum on battery which is quite a unique type of Technology while the automotive industry puts a lot of faith in their current battery lineup some outlier battery technologies may take the World by surprise so what would happen then if a battery appeared that could have a life of up to three times longer and charge up to 70 times faster than your typical lithium-ion battery these are exactly the battery innovations that graphene manufacturing group has to offer so how does this groundbreaking battery charge so quickly and what other advantages does it have this world exclusive type of battery is a significant step closer to reality thanks to graphene manufacturing group or GMG and the University of Queensland research as well as uniquest commencing their scale-up research project on the graphene aluminum ion battery not only is it cheaper faster to charge lightweight and lightweight but it also features better environmental credentials and has a longer lifespan than other lithium-ion counterparts so how much is the price of graphene aluminum ion batteries the materials used by gmg's battery including natural gas and aluminum are readily available throughout the world all those Hard To Source hard to process and hard to dispose of rare Earth elements elements would be unnecessary the average price of a Tesla 4680 battery pack was a hundred and one dollars per kilowatt hour in 2022. Mrnickel CEO of GMG calculates that this new battery costs roughly 25. 25 cents per kilowatt hour or nearly four times less than the 4680 battery from Tesla thus if you own a Tesla Model y standard range with an estimated battery capacity of 60 kilowatts per hour replacing the battery pack with a graphene aluminum ion will cost you 1 515 instead of six thousand and sixty dollars for a 4680 or a revolutionary battery this cost is really inexpensive Mrnickel also stated that he is convinced the batteries manufactured by his business would also be more cost effective than those already on the market because of a less intensive material basis and lower overall weight which clearly pays off in logistics but charge time is what most electric vehicle owners care about so how long does it take to charge a graphene aluminum ion battery the graphene aluminum ion cells from the graphene manufacturing group are claimed to charge up to 70 times faster than the best lithium ion cells this battery charges so fast it's basically a super capacitor the GMG CEO claims it charges an iPhone coin cell in less than 10 seconds these characteristics compare favorably against typical rechargeable lithium ion type coin cells which takes three to six hours to recharge but what's the Breakthrough in the weight of gmg's battery Tesla's 4680 battery cell weighed in at 355 grams compared to 89 grams for the graphene aluminum ion cell nickel is talking about the major nanotechnology breakthrough gmg's graphene cell presents developed by the University of Queensland the surface perforation of graphene allows alum aluminum atoms to sit tighter on them Nichols says that this is what allows gmg's cells to be so much lighter furthermore graphene aluminum ion batteries provide major benefits in terms of longer battery life so how many years can we actually expect at last cycled over 2 000 charge slash discharge cycles and testing so far with no deterioration in performance which means it could last up to 45 years in contrast Lithium-ion batteries have a lifespan of up to 15 years at best as their performance degrades with charging Cycles now then how would the energy density of this battery compare with lithium ion uh we're sitting at 150 160 kilo what else per kilogram and then we're sitting in a paladins you know about 7 000 watts per kilogram when it comes to energy density the graphene aluminum ion prototype cells tested so far are not that impressive they have presented an energy density between 150 watt hours per kilogram and 160 while Tesla's 4680 batteries would offer 260.
but that is not something of concern for nickel he claims that it has the potential to present three times the energy density of lithium-ion cells in fact the Oak Ridge National Laboratory has once presented an aluminum ion cell with a 1060 Watt hours per kilogram lithium ions limit would be 406 but besides that another significant Advantage this cell presents is that they have they have a higher power density of 7000 watts per kilogram for comparison Lithium-ion batteries deliver a maximum of 340. another major point that we have to discuss is safety so is this battery actually safer than lithium ion I put it into uh electric vehicles uh there's highly likely and grid stories highly likely that we won't need any cooling we're having aluminum ion batteries not overheat nearly as much as lithium ion do they are nicely below zero so far in testing and almost 20 percent of the weight and cost associated with a Lithium-Ion battery pack is attributable to high performance cooling systems which can be eliminated in most graphene aluminum ion battery use cases they don't need circuits for cooling or heating which currently accounts for about 80 kilograms in a 100 kilowatt hour pack how does graphene aluminum ion battery affect the environment directly created from natural gas graphene powder is produced by gmg's patented production technique which has clear environmental advantages using nanotechnology developed in conjunction with the University of Queensland powder is crushed into a pellet shape and implanted with small aluminum ions about 90 percent of aluminum products are currently recycled gmg's graphene aluminum ion battery would be incorporated into this well as established aluminum cycle but besides that hydrogen is a byproduct of the fabrication of graphene aluminum ion batteries which has additional use in the transportation sector to Power Fuel Cell electric cars so can it be applied in real life uh with that coin cell uh Paula plant and also our power spec GMG CEO Craig Nichols said we are currently looking to bring coin sell commercial prototypes for customer testing in six months and a pouch pack commercial prototype used in Mobile phones laptop etc for customer testing in 18 months he thinks there are a lot of opportunities for this technology and Automotive applications especially given how well it performs in fast charging and regenerative braking conditions according to GMG the aluminum ion battery is virtually interchangeable with the lithium-ion battery in many applications when do you think we'll start seeing graphene aluminum ion batteries out on the market and do you want your phone or Tesla vehicle to use this battery let me know your thoughts in the comment section down below so my proposal is to innovate in the battery chemistry and what I've been working on is a combination of aluminum itself what if there was a battery that was six times larger than a Lithium-Ion battery and can fully charge in less than a minute this was an accidental yet major Discovery by researchers at MIT that may have finally unlocked the full potential of aluminum sulfur batteries will aluminum sulfur batteries take over as the future of the battery industry a new battery is in town and it's blowing everything out of the water before it in a leap toward low-cost batteries for large-scale grid storage and international team of researchers led by MIT material chemist Donald satterway has invented a battery made of aluminum and sulfur so how is this new battery structured the researchers chose aluminum the most abundant metal on Earth as one electrode as a book and Electrode they picked sulfur the cheapest non-metal then came the time to search for the right electrolyte they avoided the flammable organic liquid electrolytes used in Lithium-ion batteries and chose a chloro illuminate molten saw salt which needs to be a liquid to be activated this battery operates at the salt's melting point of 110 degrees Celsius but sattaway says they have already brought that melting point down to 65 degrees and can see ways to get to room temperature operation but how will this new battery be priced compared to lithium ion the really exciting piece here is that the capital cost of these components is variable the three ingredients are extremely cheap and Earth abundant compared to lithium nickel Cobalt and graphite used in Lithium-ion batteries aluminum is no different from the foil at the supermarket sulfur is often a waste product from processes such as petroleum refining and widely available salts given the availability of all the components the researchers estimate the cost of the aluminum sulfur battery to be as low as 8.
