    20.2kWh - 350km 5.7kWh/100km and up to 100kW charging

    30kWh - 600km, 5kWh/100km and up to 200kW charging

    I know they're bikes, not cars, but it does sound too good to be true if I'm being honest. It will be very interesting to see if the production models live up to this

    The overall weight of the vehicle definitely plays a part here (as do aerodynamics, of course)… A 30KWh battery in something that weighs about 250kg is going to get you lot further than the same battery in something weighing 1200kg.

    If this new battery does indeed work out and is as they claim, then it could signal a new lease of life for electric motorcycles. They already sell quite poorly due to range so this announcement seems to cure that issue.

    I would consider converting my Honda touring bike to electric if I could get one of these batteries and imagine instead of 30KWh, I could fit a bit more into the frame along with the electric motor. 😊

    Another excellent video, does a lot of research into who works for Donut Labs, where the tech might have come from (Nordic Nano), billionnire investors behind it, chemistry etc etc.

    Carbon nanotubes, screen printing… production happening in Imatra, outside Helsinki. Overall it all sounds really really exciting - "Plausible and skeptical" is their verdict.

    That's a very good video. The most hopeful I would be about it, is that they have developed something and are trying to figure out how to manufacture it at scale. It was interesting when the video people ordered the motorcycle they were given a delivery date next Autumn. So, it's clearly far from "available today". But maybe the whole CES palaver was to drum up customers for the motorcycles as low volume beta testers of the battery tech while bringing in some revenue.

    Even at that, there's nothing to stop them allowing third party researchers to validate some of the claims, the energy density and environmental operating conditions, being two major ones. If they've even cracked those two that would be something. If it's a scam, it's probably the most elaborate one ever devised. I still can't get past a whiff of faking it until they make it though.

    I think there was another video from CES by Munro with CEO of Verge and it mentioned that he has these batteries in his personal bike. When you zoomed in it was taking about 100 kW from a public CCS2 charger. The standard Verge seem to top at 20-25 kW. So an elaborate hoax or not…

    A new promo video by Donut Labs on their solid state battery



  • Registered Users, Registered Users 2, Paid Member Posts: 15,607 ✭✭✭✭josip


    24 minutes long. Are Donut Labs making more money from their Youtube videos than from their batteries perhaps?

    Some polite scepticism expressed in this article. Along with some rather more direct scepticism …

    At least one large Chinese battery manufacturer strongly rebuked Donut’s claims. "That battery doesn't exist in the world," Yang Hongxin, chairman and CEO of Svolt Energy, told Chinese media last week. "The parameters are contradictory… China's technology is the most advanced globally. If China can't produce or perfect it, companies from other countries certainly can't either.”

    https://insideevs.com/news/785308/donut-labs-solid-state-skeptics-ces/

    But, are the Chinese getting a bit cocky with that kind of talk, as the post below implies? If the claims have any substance then it is not a "chemical" battery at all and utilises some completely different physical process like "spintronic nanocarbon". The poster got more than they bargained for. Lots of scepticism and accusations of using chatgpt, but I think they are genuine, though maybe still taken in by the eh … spin.

    https://www.reddit.com/r/batteries/comments/1qlijcd/the_donut_lab_battery_uses_spintronic_nanocarbon/

    The trail leads to a Swedish/German three year old startup called Holyvolt (whose name doesn't inspire confidence either) but the article below says that this company has received investment from Volvo and the billionaire Wallenberg family and they have a patent filed.

    Only 1 patent? If this battery is everything they've claimed, I'd have expected it to be defended by multiple patents covering every conceivable variation of the technology.



  • Registered Users, Registered Users 2 Posts: 274 ✭✭evftw


    The patents are a two way street but as long as you get to the Pat. Pending state before you're shipping you're good. Did I read from somewhere that the first 18 months after filing your patent is hidden from view in order to stop your competitors getting ideas before your product is ready to go?



  • Registered Users, Registered Users 2, Paid Member Posts: 13,567 ✭✭✭✭the_amazing_raisin


    I believe companies have to file patents in their home country and I think Donut Labs is based in Finland? So probably worth checking the laws there

    In any case, China doesn't respect patent law since they aren't really a thing under socialist regimes. So if I had some game changer battery technology, I wouldn't be depending on patents to protect it

    I'm still highly skeptical, there seems to be the barest amount of independent research into this type of battery. I would expect it to be at the lab concept stage, not scaling mass production

    The first independent test results on the battery are in due to be published on Monday.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,825 ✭✭✭plodder




  • Registered Users, Registered Users 2 Posts: 274 ✭✭evftw


    Yes, definitely a real place, I actually did my thesis with them back in the day. Anyway, Donut Labs are doing a good job, in my opinion, managing the online narrative of the battery here. They tackle all the doubters head on with this series.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,825 ✭✭✭plodder


    I saw that after about the "series". They are going to drip feed it in the manner a Netflix drama. I'm surprised they didn't say the test series drops on Monday … 🙄

    I hope it's genuine, but for me all these slick and shiny websites detract from their credibility. Maybe I'm just a dinosaur in that respect. But, now that VTT are on board, it needs be taken more seriously.

  • Registered Users, Registered Users 2 Posts: 274 ✭✭evftw


    Their marketing department is probably not huge so drip feed and causing hype and speculation maximises the coverage for free.



  • Registered Users, Registered Users 2 Posts: 6,564 ✭✭✭positron


    Man, with that that preface from Donut guy - this is starting to sound more thrilling than any netflix series.

    I am in it for the ride, will beg/steal to buy that Verge motorbike if the whole thing is real :D



  • Registered Users, Registered Users 2 Posts: 274 ✭✭evftw


    The first independent results are out. Just under 5 minutes charging time 0-80% with passive cooling on one side of the cell.

    Yes, about 100 Wh of energy.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,825 ✭✭✭plodder


    I still don't get it. If this does what they claim, they don't need a marketing department. "Build a better mousetrap .." and all that.

    I wonder have all the tests, including those whose results have yet to be published been done already by VTT? If not, that raises the question as to whether the same cell (and the same technology) is being tested each time. Otherwise, they could put a capacitor in the package one week, and a chemical cell the next, depending on what's being tested.

    I see you have been at the comments section.

    That the thing about using a government owned independent testing lab. Donut labs provided the cells, VTT will produce the results to confirm the claimed specs.

    Same like if say VW asks VTT to test the cold emissions of a car. The client have no say on how the lab tests. The VTT just provide hard data and protect their own reputation as an independent testing lab. And with a basic battery cell there is no way to program in a cheat software. If the cell fails it is very clear to see during the discharge test.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,825 ✭✭✭plodder


    I haven't been commenting anywhere else 🙂

    VTT certainly won't tell any lies. But, they will only test whatever they have been asked to test and using whatever they have been given.

    Having watched their video I have to say I'm getting a little excited. The test results were impressive.

    If this is the real deal I just hope they have a copy of the blue prints in a Swiss vault.



  • Registered Users, Registered Users 2 Posts: 274 ✭✭evftw


    This week's results:

    A discharge tests both at 80°C and at 100°C at 1C with the battery baked for 4 hours is impressive. But even more so that the same cell not only could withstand the tests but showed slightly more capacity on the next charge cycle at the room temperature.

    There was some superficial damage on the cell wrapping at the higher temp but the cell capacity was not lost so it was just the packaging that didn't fully survive.
