Donut Lab's Solid-State Battery Shipped April 1st... 9 Days Later, No One Received It. Why?

Added: 2026-05-09

[00:00:00]At last, Donut Lab has addressed the four most debated claims about its solid-state battery, and the figures are anything but conservative.

[00:00:08]A full charge in just 5 minutes, an impressive energy density of 400 Wh per kilogram, an almost unbelievable lifespan of 100,000 charge cycles, and a level of safety that allows operation from minus 30° C to above 100° C without any fire or explosion risk. As per the official statement, at 2:00 p.m.

[00:00:30]on February 23rd, 2026, Donut Lab will launch the first episode of a video series titled I Do Not Believe, initiating a direct campaign aimed at critics who have dismissed its technology as fraudulent. The company is also introduced a boldly titled website idonotbelieve.com, where it plans to share a collection of evidence-driven videos with the message, "We know you don't believe us, so take a look at this data." Following its reveal at CES 2026 in January, Donut Lab encountered strong skepticism from industry professionals who argued that the specifications seemed unrealistic.

[00:01:08]In response, the company submitted its batteries to an independent third party, the VTT Technical Research Centre of Finland, VTT, for evaluation. Donut Lab has emphasized that it is not depending on internal metrics for promotion, but rather on unbiased third-party results to support its claims, address concerns about real-world feasibility, and firmly state that none of the presented information was AI-generated. However, based on available details, episode 1 will mainly highlight ultra-fast charging, a complete charge in 5 minutes, and fire safety, which were among the most disputed topics at CES 2026.

[00:01:47]For the remaining claims, more time will likely be needed before concrete test data is revealed. Although the company has disclosed little regarding production costs or pricing, we will examine those aspects later in this discussion using available insights into the battery's chemistry, materials, and manufacturing process. While these estimates may not be perfectly accurate, they should offer a clearer picture of the potential cost structure. So, what is Donut Lab aiming to demonstrate with its solid-state battery? Right after the announcement, the tech community quickly divided into two camps. Supporters, those who believe this could represent a major breakthrough, similar to when Tesla introduced its first electric car in 2008, and skeptics. If successful, the battery is expected to move rapidly into real-world use with plans to integrate it into the Verge TS Pro electric motorcycle, scheduled for delivery by the end of 2026.

[00:02:41]On the other side, skeptics include experts from major competitors, such as the CEO of SVT Energy, who argue that claims like 100,000 charge cycles are physically implausible with current technology. They believe the results may only have been achieved under highly controlled laboratory conditions, making large-scale production unlikely in the near term. That said, if VTT's findings validate Donut Lab's claims, this could mark a genuine turning point for the electric vehicle sector. A 5-minute full charge, roughly equivalent to refueling a gasoline car, would remove one of the biggest obstacles to EV adoption. An energy density of 400 Wh per kilogram could boost driving range by around 70% compared to today's leading batteries.

[00:03:26]While companies like Toyota and Samsung predict solid-state batteries will arrive after 2027, Donut Lab claims it is already prepared for mass production.

[00:03:35]The company states that these batteries will power the Verge TS Pro electric motorcycle, capable of traveling nearly 600 km per charge, with deliveries expected in 2026. According to Donut Lab, the battery can endure up to 100,000 charge cycles with almost no capacity loss, far exceeding the performance of current lithium-ion batteries. Additionally, it is claimed to offer near total safety, containing no flammable liquid electrolytes, and functioning reliably across extreme temperatures without fire or explosion risk. The company also highlights the use of widely available materials, which could potentially make the battery cheaper than existing alternatives. If these claims hold true, the technology would seem almost too good to be realistic. Anyone familiar with the battery industry knows that solid-state technology is often described as the holy grail, a breakthrough that always appears to be just a few years away, particularly in light of Toyota's long-term efforts. At this stage, it's not just casual observers. Many engineers and major manufacturers believe such a battery may not even exist. Before more detailed VTT results are released, one crucial issue must be addressed. The so-called triple challenge in battery development, combining high energy density, ultra-fast charging, and long lifespan, has never been fully achieved. The first factor, 400 watt hours per kilogram, nearly doubles the energy density of Tesla's 2170 cells, and is considered theoretically feasible. However, combining that with a 0 to 100% charge in just 5 minutes, equivalent to a 12C charging rate, would result in an unprecedented level of performance. Donut Lab claims this technology is already accessible to OEMs, although deliveries are not expected until later in the year. While partial fast charging has been demonstrated before, a complete 0 to 100% charge in 5 minutes remains unheard of. Then, there is the claim of a 100,000 cycle lifespan, arguably the most critical point the company must prove. In practical materials science, such durability would be extraordinary.

[00:05:41]When Donut Lab promises future video evidence, it naturally raises doubts, with some suggesting it could be more akin to a well-produced AI simulation than reality. Traditionally, battery chemistry involves trade-offs.

[00:05:54]Increasing energy density often reduces cycle life, and ultra-fast charging, especially at 12C, generates heat that can destabilize the battery's internal structure. Consider the scale of 100,000 charge cycles. Even charging a vehicle daily for 270 years would not reach that number. In reality, daily charging at that consistency is extremely rare. Such a battery would outlast not only the vehicle, but also its owner and even multiple future generations. These specifications are undeniably remarkable. They challenge many established principles of battery physics, which is why numerous experts have labeled the claims as unrealistic.

[00:06:33]Established companies like Panasonic and Samsung SDI, along with leading research institutions such as the Massachusetts Institute of Technology and VTT, view these performance metrics as fundamentally conflicting. Meanwhile, the debate continues to grow. Much of the skepticism arises from Donut Lab's lack of transparency regarding the chemical composition of its battery.

[00:06:54]However, the company frequently references a group called Nordic Nano Group, which specializes in carbon nanotubes. If Donut Lab is using a non-traditional manufacturing approach, such as printing batteries with carbon nanotube frameworks, it could explain its confidence in rapid scalability.

[00:07:11]Though this has only increased doubts among critics. Even so, carbon nanotubes do not resolve the biggest concern, the 100,000 cycle claim. It remains unclear how the company could have tested such longevity within its operational timeline. Running that many full cycles in real time would likely take decades.

[00:07:29]Ultimately, solid evidence is essential.

[00:07:32]Everything now depends on verification from VTT. If Donut Lab's claims are validated, it could signal the decline of gasoline-powered vehicles. If not, it may severely impact the company's credibility. So, what about cost and pricing? Donut Lab's solid-state batteries are being promoted as a major advancement in EV technology with plans to power Verge TS Pro motorcycles starting in early 2026 and offering specifications beyond anything currently available. Although the company has not disclosed exact pricing, focusing instead on deployment, we can infer potential cost from its materials, chemistry, and production methods.
