EPA Urged To Approve Carbon Nanotube Use For GM’s Ultium Battery Packs

Michigan members of Congress recently sent a letter to the EPA requesting that the regulatory body expedite GM’s request to approve the use of carbon nanotubes, an advanced material slated for use in the production of the automaker’s Ultium electric vehicle batteries.

According to a recent report from The Detroit News, the bipartisan letter to the EPA is dated April 6th, and was signed by U.S. Representatives Tim Walberg, R-Tipton, Elissa Slotkin, D-Holly, and Democratic U.S. Senators Debbie Stabenow and Gary Peters.

The letter reinforces the importance of a request for approval made by Ultium Cells LLC, the joint venture between GM and LG Energy Solutions, and states that the carbon nanotube material is critical in opening GM’s new battery production facility in Delta Township. GM recently announced $7 billion in investments for its Michigan-based facilities to support the production of new electric vehicles, including $2.5 billion for battery production at the Delta Township plant, which is expected to create 1,700 new jobs.

The letter follows a recent announcement made by the Biden Administration that mentions the use of the Defense Production Act to support the domestic development and production of new electric vehicles.

Carbon nanotubes are essentially chemically bonded carbon atoms, which can be used for the efficient storage or transfer of heat or electrical energy. While great for new EV battery technology, the EPA determined in 2011 that carbon nanotubes could be a health hazard, for example, causing lung issues if inhaled.

Although approvals from the EPA are expected to take around three months, the GM request for approval in the use of carbon nanotubes is more than two months past the legal deadline. If the applications are not reviewed by May, it could result in a delayed launch for GM’s battery production facilities.

“Given the importance of this project to Michigan and to our country’s EV supply chain, we ask EPA to complete the reviews of the (applications) so that these important EV battery projects are not delayed,” the letter reads.

  • The entire EPA needs abolished. Class action lawsuits always beat them to the lunch about sever violations anyways. All they do is hamper progress and ruin people lives.

    • " carbon nanotubes could be a health hazard, for example, causing lung issues if inhaled."
      Can you spell Asbestosis and Mesothelioma ?

    • Not a fan of EFI, eh? 'Cuz without the EPA, we'd likely still be driving cars with carburetors.

    • The EPA does need to be abolished. It doesn't do its job. I don't know if its because of who they put in to run it or that the regulations are so mixed up they can't protect anyone nor advance anything. I do believe there needs to be a modern regulatory agency in place with scientists making the decisions based on data from reliable sources not paid for by corporations. They need to see the whole picture. For example, if the EV batteries are a health hazard, can they be sealed well enough that they are not? Like our current car batteries! EPA should ask: What is the plan of disposal? No is not an answer. How can we find a solution to this great idea, should be progress forward for most proposals unless the product or conduct will obviously be a health hazard with no solution, like RoundUp.

  • ELECTRIC VEHICLES ARE A LONG TERM
    LOSER. ALL THIS INVESTMENT IS A

    THE TECHNOLOGY IS JUST WRONG, FOR CARS. ...

      • The dumb person here is the one who thinks the US is far right. Probably a butt hurt kid mad the government won't give you everything.

    • Wasted fill-up time. I took me 4 seconds to plug in my car and 4 seconds to unplug it. I do that twice a week. That's about 16 seconds of wasted time for the 426 miles I drive per week. That 400 miles cost me $16. The battery will last approximately 1,000,000 miles, or approximately 96 years at my 15,000 miles per year rate. My 1 ton diesel was replaced right before I bought it (should have been a big red flag but it lasted me a couple years before I sold it). That cost $14,000 to have done. Replacing a Tesla Model Y battery pack is between $10,000 and $12,000. That isn't exactly comparing apples to apples but the diesel was the most recent vehicle I had that had an engine replacement. I needed it for the enclosed car hauler we had at the time. I've since downgraded to a half ton.

      The Model Y comes with 8 years of battery coverage. I suppose you'd never know when buying it what the cycle life was like but you can use the year of production and mileage to get a really good idea. It isn't like you have to worry that the previous owner never changed the oil, or transmission fluid, or differential oil. They just work. And, they work really well. At least that's been my experience. Buying used is always a crap shoot.

      You could ask all the fear mongering questions about a gas car. Did the dealer lie? Has the oil ever been changed? Has this car been left to idle for hours on end without the mileage showing that? Will the engine need replaced soon? The transmission?

      Charging the Tesla is SO simple and fast. Daily, you just plug it in when it gets low and when you get ready to go to work the next day, it's all charged and ready to go. No driving to a gas station, waiting in line (Well, Sam's club where I fill up my truck always has a line. I'm a little jealous my wife drives the Tesla), there's no oil change you have to wait on, there's literally nothing you have to do maintenance-wise but rotate tires, change wiper blades, and refill washer fluid.

      There is no government conspiracy that made us buy the Tesla. It's just better in every way but one. Road trips DO take a little longer and require a little planning though the car DOES plan the stops for you. It took me almost one hour longer from Nebraska to Louisiana than it took my wife making the same trip in a rental van (too many people for the Model Y).

      Anyway, I'm telling you, the last two years of having the Model Y have been absolutely wonderful. Well, for my wife. I still drive my truck. But, as soon as I can, I'll dump that for an EV. So good. Once you've had one, you won't want to go back to gas.

      My opinion, of course. Cheers.

  • I HOPE THAT OUR AUTO CORPORATIONS
    ARE NOT IN BED WITH THE GOVERNMENT.
    IF IT IS THE GOVERNMENT THEY ARE COUNTING
    ON FOR A MARKET, THE RESISTANCE WILL BE
    HUGE. IF GM AND OTHER BELIEVE THAT THE
    GOVERNMENT WILL FORCE EVERYONE TO BUY
    AN ELECTRIC CAR THAT IS THE ONLY WAY ALL
    THIS INVESTMENT WILL PAY OFF. GOVERNMENT
    COERCION OR REGULATION WILL BE THE ONLY
    WAY THEY WILL SELL STORAGE BATTERY TECH
    AS A REAL MARKET FOR THESE NEW ELECTRIC CARS.

    UNTIL GM AND OTHER SOLVE THE STORAGE
    BATTERY PROBLEMS THAT'S WHAT IT WILL TAKE
    TO MAKE A MARKET BIG ENOUGH TO MAKE IT
    WORTH SPENDING SO MUCH INVESTMENT MONEY,

    LETS HOPE THIS IS NOT WHAT GM AN OTHERS
    HAVE IN MIND, IT WILL BE ANOTHER COVID BOON
    DOGGLE WHERE THE GOVERNMENT FORCES ALL
    TO TAKE THE JAB. AND THE JAB IS WHAT CAUSES ALL
    THAT SICKNESS AND DEATH.

    THINK AMERICA THINK!!

    • If you're 82, you must missed sitting in gas lines, 55 mph speed limits and filling your vehicle up based on your license plate in the '70s ...

  • Yeah, that's why a normally very conservative Honda announced a $40 billion (with a B) electric car program.

  • IMHO THE RESEARCH THAT WILL GIVE YOU UNENDING POWER WITHOUT POLLUTION IS HYDROGEN. 2/3 OF THE EARTH IS WATER. SO, NOT GONNA RUN OUT. NO NEED FOR HOURS ON A CHARGER, JUST FILL THE TANK WITH HYDROGEN AND DRIVE AWAY. NO EXHAUST POLLUTANTS JUST A LITTLE WARM WATER. CANADA IS WELL ON THE WAY TO USING HYDROGEN. MUSK TALKS ABOUT SCALE. DOES ANYONE HAVE ANY IDEA HOW MANY BATTERIES IT WOULD TAKE TO POWER THE EARTH? GAZILLIONS. DOES ANYONE KNOW HOW WE COULD EVER DIG THAT MANY NEEDED MINERALS OUT OF THE EARTH? NO!! MINERALS THAT ARE NOT ALL IN THE USA BY THE WAY. SO THERE'S LOTS OF GEO POLITICS TO FIGURE OUT. GREED CORRUPTION WOULD JUST BE THE TIP OF THAT ICE BERG.

    BUT I STILL CAN'T GET OVER HOW ANYONE WOULD THINK THAT THEY COULD GET A MILLION MILES FROM A NICAD BATTERY PACK THAT WEIGHS A TON. THERE IS NO WAY ANY NICAD BATTERY THAT GIVES YOU 300 TO 400 MILES PER CHARGE COULD CHARGE UP THAT MANY CYCLES. I MEAN THAT'S WAY FAR OUT IN SPACE ... THAT'S 250,000 CYCLES. YOU THINK YOU CAN GET 250,000 RECHARGING CYCLES OUT OF A NICAD BATTERY? GOOD LUCK.

    JUST SAYIN ... WE ARE CHASING THE WRONG RABBIT. IF WE INVESTED AS MUCH MONEY IN HYDROGEN GENERATION TO MAKE IT CHEAPER THAN GAS WE WOULD HAVE A FUTURE. IF WE CONTINUE DOWN THIS DEAD END OF NICAD STORAGE BATTERY PAPER WEIGHTS WE WILL EVENTUALLY BE BACK TO HYDRO CARBONS. LOTS OF THOSE IN THE EARTH RIGHT HERE IN THE USA. LETS PUT THE MONEY WHERE IT WILL DO SOME GOOD.

    HAVE A GOOD DAY ...

    • Hydrogen is a good idea but it's needs to be commercial only as it's volatile (imagine a 17 year old filling a hydrogen vehicle station activity talking on a cellphone while pumping..)

  • ONE MORE THING. WE CAN'T FORGET ABOUT PHYSICS. THAT'S WHY TODAY WHEN ELON MUSK WAS ON TED HE MENTIONED PHYSICS BEING HIS BIG SWEET SPOT, BUT NOT A WORD ABOUT HYDROGEN CREATION. I GUESS HE'S PRETTY MUCH BURIED IN BATTERIES. I CAN UNDERSTAND HIS POSITION. NOT TO MENTION IT AT ALL??? JUST THE SAVINGS IN WEIGHT WOULD BE ENORMOUS. ANYWAY ...

    THAT I BELIEVE IS THE TRUE ANSWER TO THIS POLLUTION THING. EVERY WOKE CHILD IS ALL SCREWY ABOUT NOT POLLUTING ANYTHING YET THEY DON'T KNOW A DAMN THING ABOUT PHYSICS. THE BLIND LEADING THE BLIND...

  • I bought an EV 6 months ago. I've put 10,000 miles on it and the cost has been 4 cents/mile. Please do the math and see what your big truck costs you per mile....IE:.... (price of gas divided by your MPG = cost/mile). If you can beat me than we can talk.

  • Fuel cells are stupid expensive and cars using them still need batteries. Producing hydrogen for fuel cells is also stupid expensive. Far more costly that fossil fuels and electricity. Futhermore, there's no hydrogen distribution network to sell the hydrogen. Fuel cells will never be economically viable in passenger cars. Maybe commercial vehicles (trucks, ships, construction equipment) when fuel cell and hydrogen costs decrease.

  • I suppose. I mean, I like the Lightning well enough. I just have had a really good experience with Tesla. I know the looks of the Cybertruck are ... Unconventional, to say the least. But, I don't need a topper and just need to haul an 18' cargo trailer occasionally and my boat more regularly but not far. So, I've put a deposit on the Cybertruck. Tesla recycles 100% of their battery packs (accidents happen) so I don't feel there will be some toxic site for our cars someday.

    GMs Ultium battery is supposed to live 1,000,000 miles which is more than most of us will drive in our lives. Tesla claims the same. I typically don't keep vehicles that long. I get bored with the same thing day after day... (Don't tell my wife I said that!)

    I don't understand the anti-Tesla angle. They are an American car company making cars right here with parts from right here with people from right here.

    Silverados in the US are made here, Mexico, and Canada.
    Ford? Same thing.
    Tesla? All US Tesla's are made in the USA. They have plants in China and Germany (just like Chevrolet and Ford) but those vehicles stay overseas.

  • PLEASE DON'T THINK I AM PUTTING DOWN THE TESLA. I THINK THE ARE QUITE NICE. ELON MUSK IS ONE OF MY FAVORITE PEOPLE. MAINLY BECAUSE HE IS AN HONEST MAN. A TESLA WITH A STORAGE BATTERY IS WHAT IT IS. I’M JUST SAYING THE DAMAGE TO THE EARTH BUILDING THESE THINGS IS ENORMOUS WHEN THERE IS AN ALTERNATIVE TECH RIGHT IN FRONT OF THEIR FACES. BUT NOBODY IS INVESTING MUCH IN IT. MY SENSE IS THAT ALL THE DIGGING NEEDED TO BUILD STORAGE BATTERIES NANO TUBES OR NOT IS GOING TO CAUSE A STIR ONCE THE BIG GAPING HOLES IN THE EARTH START CAUSING TROUBLE. NOT JUST UNSIGHTLY BUT DAMAGING AND POLITICALLY VOLATIL.

    WE WILL NEVER BE FREE OF HYDROCARBONS. THEY ARE CIVILIZATION. WITHOUT THEM WE WOULD BE BACK ON THE PRARIE. BUT WATER IS EVERYWHERE. TO SEPARATE THE HYDROGEN AND USE IT FOR FUEL SEEMS LIKE A NATURAL. WE.ARE.WELL EXPERIENCED IN HANDLING COMBUSTIBLE LIQUIDS. TO COUPLE THAT FUEL TO AN ELECTRIC MOTORS/S MAKES A LOT OF SENSE. I WOULD BUY ONE OF THOSE. NOT MUCH DIFFERENT THAN A GAS GUZZLER.

    I SIMPLY BELIEVE THE CHOICE OF RECHARGEABLE BATTERIES WAS NOT WELL THOUGHT OUT. FUEL CELLS HAVE BEEN AROUND SINCE MERCURY THE FIRST ROUND OF SPACE VEHICLES BACK IN THE SIXTIES. I CAN’T UNDERSTAND WHY ITS BEING IGNORED AS A FUEL FOR CLEAN TRANSPORT. IT SEEMS PERFECT.

    JUST SAYIN...

  • Cybertruck is vapourware. We will not see any for sale on the near future. Even Ram will beat Tesla to market with an electric truck.

  • Tesla and many Chinese manufacturers are moving to lithium iron phosphate (LFP) batteries that are cobalt and nickel free, cheaper, and have a longer life cycle. Energy density is improving for LFP as well.

  • Good point. Fuel cells have been around longer. They just aren't as efficient electrically, volumetrically, or in weight. You lose efficiency in each conversion. I will agree that long-term and industrial level storage should be done with hydrogen fuel cells. I'll even agree that right now, it makes sense to use them for large vehicles like big rigs. However, because batteries have been seeing massive improvements, we are close to seeing a doubling of battery storage capabilities which will give us cars with capabilities of 1,000 miles between charges (the Cybertruck already is going to have 500+ miles of range without the new-tech batteries. Tesla has a method of getting Lithium in a much more sustainable way. Something I didn't know was that when they recycle batteries, they can recover 100% of the elements and with processing, they can produce one new one for every used one recycled. That means that maintaining levels of batteries will only require recycling. Only new batteries will require mining. Lithium is very widely available. Cobalt is being phased out. The batteries are rapidly moving away from the detrimental environmental impacts. They aren't there yet but they will get there. The advances are driven by early adopters who are basically funding advancements (the same goes for every field)
    What I'm looking forward to is that if we can cut our oil usage by just 8%, we will no longer have to import oil and will be self-sustaining. A new pipeline would make it easier to get oil from Canada but would not increase the amount. EV adoption or even fuel cell adoption will help get us there. You seem to be pro-hydrogen fuel cell. How long have you had your Honda or Hyundai? I haven't heard a lot about them but they are the only ones available. I support electric over hydrogen because the infrastructure is already in place (everybody has electricity at home but not hydrogen). I'd love to hear a first-hand account.

    I am not anti-gas or some kind of tree hugging extremist. I just really like the power and smoothness and simplicity of our Tesla.

  • At this point, I think Tesla decided to see what the competition was going to put out. Tesla is not hurting in sales as everything is sold out now. I think we'll see the first production Cybertrucks by the end of this year and it will have more range and be less expensive than the others. It is NOT vaporware but it is running later than planned.
