Helsinki/Berlin – With the current date marking February 21, 2026, the global battery sector faces a potential turning point starting Monday: Finnish startup Donut Lab will begin releasing independent test results from the VTT Technical Research Centre of Finland on its all-solid-state battery technology. Already integrated into production vehicles from Verge Motorcycles, the innovation promises to reshape electric mobility through superior energy density, rapid charging and extended lifespan, positioning Europe ahead of established leaders in the United States and China.
Donut Lab, based in Espoo, unveiled its Donut Battery at CES in January 2026 as the world’s first all-solid-state battery ready for serial production in vehicles. The technology powers the updated Verge TS Pro electric motorcycle, with deliveries starting in the first quarter of 2026. Customers can select modular packs of 20.2 kWh or 33.3 kWh, delivering ranges up to 217 miles or 370 miles respectively. The battery supports fast charging at up to 200 kW, adding significant range in under ten minutes – in some claims as little as five minutes for a full charge.
Key performance figures include an energy density of 400 watt-hours per kilogram, roughly double that of many current lithium-ion batteries (typically 200-300 Wh/kg). This allows for longer range without increasing vehicle weight or compromising design flexibility. The battery maintains over 99 percent capacity retention across extreme temperatures from minus 30 to plus 100 degrees Celsius and is engineered for up to 100,000 charge-discharge cycles with minimal degradation. Unlike conventional lithium-ion systems relying on liquid electrolytes prone to thermal runaway and fire risks, the all-solid-state design uses solid electrolytes for enhanced safety and stability.
The materials emphasize abundance and geopolitical neutrality, avoiding rare or critical elements like lithium, cobalt or nickel. This approach reduces costs below those of traditional lithium-ion batteries while minimizing environmental impacts from mining. Production is scaled to gigawatt-hour levels, available for OEM integration worldwide.
Speculation in industry discussions links aspects of the technology to German company CT Coating AG from Königswinter. The firm specializes in innovative, non-toxic coating processes using selected materials, advanced pigments and cost-effective methods. Its expertise includes nanotechnology for precise, nanoscale layer applications in energy-related fields. Such nano-coatings can protect electrodes, suppress dendrite formation – metallic needle-like growths that cause shorts – and enhance ion conductivity. While no direct official partnership is confirmed in public statements, community analyses suggest possible origins or influences from CT Coating AG’s nanomaterial-based cells, potentially contributing to the high-rate performance and stability claims.
The global unveiling of validation data commences Monday, February 23, 2026, at 2 pm CET. Donut Lab commissioned VTT, a respected state-owned Finnish research institution, to perform independent laboratory measurements on performance metrics including capacity, charging behavior, cycle life, safety and thermal characteristics. Results will roll out in a video series titled „I Donut Believe“ across Donut Lab’s channels and a dedicated website (idonutbelieve.com). The series addresses widespread skepticism following CES, where experts questioned the feasibility of combining such parameters in a real-world, producible battery. Full measurement reports will accompany detailed video documentation explaining setups, procedures and findings for transparency.
This development arrives amid intense market scrutiny. China controls over 80 percent of global battery production, leveraging scale and low costs through companies like CATL and BYD. The United States, despite billions in subsidies via the Inflation Reduction Act, holds under ten percent share and progresses slowly in domestic scaling. Europe aims for greater independence, targeting eleven percent of worldwide investments by 2030, supported by initiatives in renewable integration and local manufacturing.
Donut Lab’s approach disrupts this landscape by prioritizing sustainable, locally sourced materials and proven real-world application in Verge Motorcycles. The Verge TS Pro, already in production with the new battery, demonstrates practical viability rather than lab prototypes. This could accelerate electric vehicle adoption by overcoming persistent barriers: high costs (batteries comprise up to 40 percent of vehicle price), limited range and lengthy charging times.
Historically, lithium-ion batteries evolved from Sony’s 1990s commercialization for consumer electronics to Tesla’s automotive scaling in the 2010s. China dominated through massive capacity investments. Europe and the US have pursued catch-up strategies, but breakthroughs remain rare. Donut Lab, a smaller player, claims to leapfrog incumbents with a focus on solid-state advantages: higher voltage tolerance, reduced weight and superior recyclability.
Skepticism persists. Battery specialists and competitors have labeled the claims contradictory or overly optimistic, with some suggesting the technology resembles a high-performance capacitor rather than a true battery. Forums and analyses debate origins, including potential ties to CT Coating AG’s nano-structured cells. VTT’s independent data will be pivotal in resolving doubts.
Economically, the battery market exceeded 150 billion US dollars in 2025 with continued growth projected. Validated success could create jobs in European manufacturing, cut import reliance and lower EV prices. For mobility, it enables lighter, longer-range vehicles and better grid support via stationary storage.
Challenges include full-scale ramp-up, supply chain diversification and integration into diverse platforms. Yet the Monday release marks a critical milestone: Europe asserting leadership through verified innovation in nanotech-enhanced, solid-state solutions.
In summary, as independent results emerge from February 23 onward, this Finnish-German influenced advancement – bolstered by nanoscale coating expertise – may finally deliver on long-promised solid-state potential, outpacing US and Chinese incumbents in sustainability and performance for the electric future.
