海外TECH	Engadget	What’s going on with Donut Lab?	https://www.engadget.com/transportation/evs/whats-going-on-with-donut-lab-173007121.html?src=rss	In January a Finnish Estonian startup proclaimed it had developed a truly solid state battery a holy grail for the technology industry Donut Labs cell wasn t just solid state however It claimed it was made from cheap and easily available materials would charge to full in a few minutes and last for hundreds of years If real such a device would change the face of the world which is why plenty of people don t think it is And as the company makes more effort to demonstrate it is telling the truth the more holes people are finding to poke their fingers into So what the hell is going on with Donut Labs battery After many weeks of research I m throwing my hands in the air tired of the endless dog and pony show the company is putting on Solid state batteriesConventional batteries have improved a lot in the last few decades but remain imperfect in many ways Cells found in electronics and EVs commonly use liquid or gel polymer as an electrolyte These electrolytes are the cause of thermal runaway where the heat of a battery increases exponentially and can become a primary cause of battery failure and fire Plus they re pretty fussy requiring a consistent temperature for peak performance and to be treated pretty delicately It s why the industry has raced to develop a solid state battery that eliminates the liquid or gel polymer Because of their higher energy density solid state batteries should be lighter and smaller per watt than conventional batteries These benefits would be enjoyed widely but are vital for an EV where weight and size dictate so much of how it operates Solid state batteries are at far less risk of thermal runaway and should work in a much wider temperature window Now we are already seeing plenty of semi solid batteries coming into the market with fully solid cells expected in the near future Chinese battery giant CATL told BatteriesNews at the end of that its first small scale production of solid state batteries is anticipated to begin in However those first production runs are likely to be limited rather than global rollouts Donut LabEnter Donut Lab The startup is a subsidiary of Finnish motorcycle maker Verge Motorcycles famous for its Tron style hubless in wheel rear wheel motor Verge says it has built the world s most powerful electric motor family and that it made all the components needed to build an electric vehicle Verge s motors have since been incorporated into Longbow Motors recently announced Speedster EV At CES Donut Lab announced it had built the world s first full all solid state battery It said this wasn t just a prototype but was ready to power up production vehicles now In a glossy promotional video the company said it had solved the issues the whole industry had been working to solve for decades There was nothing but upside with none of the trade offs its competitors had been forced to make while developing their own solid state batteries And it was ready to be incorporated into EVs starting today Verge Motorcycles announced it would add the battery into its TS Pro with shipments expected to begin Q Donut Labs batteryThe company s extensive list of claims begins by saying the cell has an energy density of Wh per kilogram roughly twice the energy density of the best lithium ion battery on the market Right now you should expect to get around charge and discharge cycles out of any half decent battery Donut Labs is promising its cell will last for a whopping cycles even if you re fast charging the cell The company promises users will be able to reach an percent charge from zero in around five minutes and get to full in under six Donut said the cell offers a clay like freedom of design adapting to the specific needs of a specific product rather than the other way around Naturally pumping all of that power into such a small cell will mean it ll need a lot of babying right Not according to Donut Lab which says its battery will operate in temperatures as low as degrees Celsius Fahrenheit or as hot as degrees Celsius Fahrenheit And to top it off it s made from common easily available and cheap materials which are geopolitically safe rather than from rare earth minerals sometimes held by rival nations All of that means the cell will be cheaper to produce than the equivalent lithium ion cell and best of all Donut said the battery is ready for scaled production A battery that promised some of these features would be world changing one offering all of them would be world shattering It would upend supply chains shift the global balance of power potentially eliminate reliance on so called rare earth minerals and supercharge EV adoption But Donut Lab offered no proof for its claims no hint as to what its process was based upon and no sign it had the manufacturing capacity to deliver on its promises Naturally a lot of people just didn t believe what they were seeing and hearing and called BS People are suspiciousYang Hongqin CEO of Chinese battery maker Svolt was quoted by CarNewsChina as saying any person with even a basic understanding of the technology would think it s a scam Finnish newspaper Iltalehti reported that CATL s venture capital head Ulderico Ulissi described the matter as clearly fake That comment prompted Donut CEO Marko Lehtim ki to respond on LinkedIn saying that Ulissi would regret the arrogance Tom B tticher CEO of battery startup Litona posted on LinkedIn his belief Donut s technology is actually tied to a company Donut invested in Nordic Nano B tticher found a pitch deck which is no longer available but is here at the Internet Archive which described Nordic s energy storage technology as a supercapacitor Some have pointed out that Lehtim ki has a track record of making strong claims about his products On May he announced an AI startup ASILAB and said in a similarly glossy launch video that his team had created a synthetic counterpart to the human brain Its first product ASINOID Lehtim ki said is a dynamic self developing organism designed to grow in capability and in consciousness The company said it would open up access to ASINOID but I ve been unable to find any evidence that any such access has been granted ASILAB has not responded to our request for comment Similarly salty write ups can be found in ElectronicDesign MIT Tech Review Interesting Engineering InsideEVs and just about every Reddit YCombinator and Hacker News thread discussing the technology I Donut Believe comIn response to the minor social media backlash Donut Labs went on the offensive It launched the website IDonutBelieve com promising a weekly drop of so called evidence to support its claims In a polished video introduction Lehtim ki said the criticism comes from parties with vested interests such as competitors He addressed the above attack lines directly saying people have been assembling theories from scraps of online data to create an untrue picture He also denied claims the battery was a supercapacitor In the same video Lehtim ki said the media has amplified so called experts from the battery industry taking their opinions at face value Naturally rival researchers who would stand to gain by taking down a potential challenger have a natural desire to rubbish Donut s claims But because many of them are credentialled experts in the field their authority was elevated above his own Crucially Lehtim ki said Donut didn t publish validation tests at the time of announcement as it would have been similarly dismissed by those same biased voices By holding the proof back he said it forced Donut s competitors to essentially show their hand making it easier to refute them To do so Donut engaged VTT Finland a government owned research organization which offers testing services to third parties VTT has conducted specific tests on cells supplied by Donut the results of which the company has released piecemeal over several weeks It s important to note that VTT s reports don t make any statements which could be seen to support Donut s claims For instance it says it was asked to conduct independent charging performance tests on the energy storage devices supplied by the customer which the customer identified as solid state battery cells The testsDonut Lab published a test for five weeks each one each one designed to show off one key feature of the battery Test One saw VTT fast charge a cell beyond the limit of a regular battery after which it still had close to of its charge available for use In Test Two VTT charged the cell to full and then discharged it in high temperature environments Once that was done the cell was charged again at a normal temperature but researchers noted that the pouch lost vacuum Donut Lab later said the vacuum loss was caused by the packaging materials not being able to withstand the temperature rather than an issue with the battery itself A VTT spokesperson told me during the final stage of manufacturing all gases are removed from the cell and the cell is sealed tightly under vacuum conditions The cell feels firm If the cell loses its vacuum it usually becomes slightly soft and swollen Essentially if a battery loses its vacuum it means it s started swelling which is visible in the photos from the report Swelling is fatal to a traditional lithium ion battery and potentially the device it s connected to Test Three purported to disprove the idea that Donut was secretly selling a supercapacitor so VTT charged the cell to full and let it sit idle for days At the end of that time the charge level of the battery appeared to hold steady with a small drop commonly seen in all batteries Which appeared to confirm the cell was a battery rather than a capacitor which may struggle to hold its charge over longer periods of time Test Four was conducted by Donut Lab itself taking a prototype of its battery in a Verge motorcycle to a fast charger The cell had a rated capacity of kWh and it was charged from percent to percent ーaround kWh ーin minutes Test Five focused on the cell from Test Two which lost its vacuum to prove it was not broken VTT s report says it cycled the broken cell times up to percent of its full charge to see what happened VTT s researchers said it was possible to cycle the cell but that its capacity began to degrade after the first few and by the end of the process it had fallen to nearly half of its original figure The cell itself had swelled however with VTT saying the cell thickness had increased by percent and the cell pouch was firm Donut Lab boasted that while a lithium ion battery in this condition would likely explode its own cell still worked When contacted VTT said it did complete an assignment for Donut Lab but declined to make any specific comment on confidential client assignments On March Verge Motorcycles posted a video claiming the TS Pro Gen the first to carry Donut s solid state battery was ready to ship Given March is the last day of Q it s the latest possible day the company could announce this and say it has honored its promise The accompanying write up said the bike will ship with either a standard range kWh battery with a range of km miles or a long range kWh battery that should run for km miles April Then on April the company posted a video beginning with a fakeout scene of Lehtim ki admitting the whole thing had been a scam One hard cut later and the clip pivots into a Q amp A with an off screen interviewer asking why anyone would believe Lehtim ki on April Fools Day He dryly responded that people don t believe him the rest of the time but that the ambiguity provided by the occasion was a benefit He would be able to speak more freely with less fear of censure or so he claimed Lehtim ki said the series of I Donut Believe tests already published were another part of his D chess strategy to get battery rivals to show their hand And that the tests undertaken by VTT were on a first generation battery while the company was already working on the second He did concede that the claims around cycle life were based on estimates and that if they wanted to prove it they would have needed to start testing a decade or more ago But he batted away questions about energy density weight and size saying you wouldn t ask a woman her age and you never ask a battery its weight He added those questions would be answered in future in more episodes of the I Donut Believe complete multimedia experience Donut Lab YouTube Consequently the weekly video series will continue until the full details of the first generation battery have been revealed Lehtim ki then teased that this cell would be shipping and the videos will shift focus to the second generation cell with far better specs But producing the I Donut Believe series ーwhich it s worth mentioning is a marketing function of the company trying to sell us a new product ーwas costly and had run over budget which has led the company to open its own merch store including t shirts and hoodies If you re already facing credible accusations of perpetuating a scam and your big reveal is to double down on misdirection it s not a good look Lehtim ki ended the video by talking about how much better Donut Labs second generation battery was with a staged outtake showing a notepad listing the specs for a third generation battery with Wh kg energy density C charge speed and durability for a million cycles ーdue to be announced at a future CES AnalysisThe release of these tests has seen interested parts of the internet engage in a near Zapruder level of interrogation People have pored over every facet of the reports and videos trying to work out what exactly is inside Donut Lab s battery A number of prominent YouTubers have produced deep dives on the matter each one claiming the cell is real or not There are countless Reddit threads where people are picking apart the voltage graphs and claims in the reports And it seems every week there is a new revelation about what Donut s technology is and where it came from Plenty of people online are chasing down threads tied to energy technology companies like Holyvolt and CT Coating or examining the charge graphs against a nickel manganese cobalt cell I ll spare you the details for now Finnish newspaper Kauppalehti decried the results of the fifth test saying the cell didn t lose its vacuum It quoted Finnish battery expert Juho Heiska who said the company has just used a traditional cell that is sufficiently hardy to withstand this abuse in the short term Donut Labs YouTube Even to a non expert there s clearly a gap between what Donut promised and what its tests are showing For instance the company said it would be able to fast charge a Verge TS to full in less than minutes But in Test Four it took minutes to get from percent to percent ーnot a bad charging time but certainly not as swift as the company pledged That said if we take the company s claims at face value then being able to fast charge a battery at that sort of speed with just air cooling is noteworthy At least it will be if you can do that regularly and one or two trips to the charger don t leave you with what Reddit likes to call a Spicy Pillow afterward Unfortunately it s been difficult to find battery researchers willing to go on the record about Donut Labs I sought out experts in academia who were not tied to industry backing and so wouldn t be accused of having a vested interest in the matter But all of them refused to go on the record More than one I contacted said they were well aware of the saga and had plenty of feelings about the matter But they were unwilling to expose themselves to the potentially intensive social media scrutiny that comes from weighing in I m Donut skepticalPersonally I ve been suspicious of how Donut Labs has gone about demonstrating its technology After all if you were actually confident about your product and its technology you would surely be able to share basic information about it Table stakes stuff like the weight and size of the battery cell you handed over for testing As ElectronicDesign notes data like that would help us all see if its energy density claims hold water Instead the company has engaged in an ornate kabuki which only serves to further undermine its case You can go a long way on the back of very little trust but the grander the promises get and the less eager you are to share evidence the faster that trust evaporates And you know how someone spends a lot of time talking around something so as to not be caught in a deliberate lie Donut Labs videos can feel a lot like that since there are so many things it s intentionally not making clear Rather than taking the chance to offer even a small amount of substantive evidence to support its initial claims it has instead moved the goalposts So rather than talking about the efficacy of its first generation product it s dangling the second and third in front of us to hopefully distract us Look I want to be even handed and give the company the fairest shake that I can and obviously if the cell can deliver on its promises I ll be overjoyed But we ve all seen scams before and until Donut Lab starts offering up a lot more data it hasn t earned anything close to the benefit of the doubt This article originally appeared on Engadget at	2026-04-01 17:30:07
