At 2:00 PM CET on February 23d, a video will split the battery world into two eras: the time before and the time after the validation of the “Donut Battery” by the VTT Technical Research Centre of Finland. If the expected data confirms the Finnish startup’s extraordinary claims – 400 Wh/kg, five-minute charging, 100,000 cycles – the tectonic plates of global power will shift not only between Europe and China but directly beneath the Pentagon .
Behind the Finnish surprise success lies a German core component: CT Coating AG from Königswinter. Its highly specialized screen printing and coating processes for bipolar electrodes are considered the “secret booster” of the Donut cell. Europe is proving its strength in the “intelligent stealth mode” – discreet innovation from the Mittelstand, protected by strict EU investment controls. China, in turn, is not reacting with panic but with its signature discipline: scaling at costs 50 percent below Western production .
But the real explosive power of this three-way constellation unfolds on the North American continent – and inside the corridors of the US Department of Defense.
The Pentagon’s Wake-Up Call: 80 Percent Dependency
For the US military, the Donut Lab announcement could not come at a more sensitive moment. The Pentagon is currently finalizing a comprehensive battery strategy, mandated by Congress in the 2025 defense policy bill and expected to be signed by March 2026 . The urgency is driven by a stark reality: nearly 80 percent of Defense Department weapons systems rely on critical minerals, with much of the supply chain concentrated in China .
Eric Shields, the senior battery advisor in the Pentagon’s industrial base policy office, has made no secret of the challenge: “What we know is, especially from the battlefield in Ukraine, that batteries are really important. They’re important for enabling capabilities like drones, communications, and many other things that we need to fight and win” .
The Donut Battery’s potential validation creates both an opportunity and a strategic dilemma for Washington.
The Drone Revolution: 300,000 Reasons to Care
The most immediate impact zone is the military’s exploding demand for unmanned systems. The US armed forces plan to procure up to 300,000 drones by 2028, requiring an estimated 30 million specialized cells . As Daphne Fuentevilla, the Navy’s deputy director for operational energy, put it bluntly: “We need these batteries yesterday. I need way more energy and power available in all of my platforms than what I’ve been fielding to date” .
The Donut Battery’s claimed performance – particularly its energy density and rapid charging – aligns almost perfectly with military requirements for small unmanned aerial systems and one-way attack drones, where “the capability that I can deliver is directly proportional to the amount of battery energy that I can put on those systems” .
Three Scenarios for the Pentagon
As the VTT data lands on desks in Washington, defense planners are likely gaming out three scenarios:
Scenario 1: Licensing European Technology
The most straightforward path would be for US defense contractors to license the Donut Lab technology, potentially through existing partnerships with European allies. The Pentagon has emphasized working with “allies and partners” as a core pillar of its strategy . However, this would still leave critical intellectual property in European hands and raise questions about supply chain security during a conflict.
Scenario 2: Parallel Development Through ARPA-E
The Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) is already funding leapfrog technology through its JOULES-1K program, which aims to develop batteries with four times the energy density of current lithium-ion within 24 months . Six teams, including Silicon Valley startup And Battery Aero, are receiving up to $15 million to produce manufacturable prototypes . If Donut Lab succeeds, it validates ARPA-E’s ambitious targets – but also raises the question of why European innovators got there first.
Scenario 3: The “Walled Garden” Approach
The most likely response is a strategic hedge: accelerate domestic programs while selectively integrating allied technology, all within a tightly controlled defense supply chain. A 2028 law already prohibits Chinese battery components in Pentagon supply chains . The question now is whether European batteries will be treated as trusted substitutes or potential competitors.
Standardization as a Weapon
One of the Pentagon’s primary focuses is standardization across the bewildering array of military platforms – from small drones to undersea vehicles to large-format batteries embedded in ships . Marnie Bailey from the Army’s C5ISR Center emphasized: “Technology is moving fast. The Army is moving fast, the Navy is moving fast, DOD is moving fast” .
If Donut Lab’s technology proves superior, the Pentagon may face pressure to adapt its standardization efforts to accommodate a European-designed cell – a process that could take years even in an accelerated timeline.
The Funding Reality
The money is there. The fiscal year 2025 budget reconciliation includes:
· $1 billion for bolstering critical mineral production capabilities
· $2 billion to upgrade critical mineral stockpiles
· $5 billion targeted toward developing critical minerals supply chains
But as Eric Shields noted, while “the significant resourcing the department just received… a lot of those decisions are still being made. Stand by is kind of the message, because the requirements are coming, but we don’t have them just yet” .
The Chinese Counter-Play
Beijing is not idle. Chinese firms like CATL and BYD aim to capture 40 percent of the global solid-state battery market by 2030 . Through joint ventures with European automakers and aggressive investment in Hungarian production facilities, China is positioning itself as an indispensable partner even as Europe celebrates its breakthrough .
For the Pentagon, this creates an uncomfortable reality: the two poles of battery innovation – Europe’s cutting-edge chemistry and China’s unmatched scaling capacity – are both outside direct US control. The defense establishment’s traditional preference for domestic sourcing may need to accommodate a more complex reality of allied dependency.
Outlook: The Three-Block World
The February 23 validation thus becomes a stress test for three competing models of industrial policy:
- Europe as inventor: Disruptive innovation from small units and cross-border research networks
- China as producer: Unmatched scale, speed, and cost discipline
- The US as “walled garden”: Prioritizing defense applications over mass-market competitiveness
The Pentagon’s response will reveal whether it views the Donut Battery as a welcome allied breakthrough or a reminder that even friends can become strategic competitors in the race for next-generation energy storage. As the Navy’s Fuentevilla put it: “For these systems in particular, the capability that I can deliver is directly proportional to the amount of energy and battery energy that I can put on those systems” .
The Donut Battery promises more energy. The question is whether it will power American drones – or simply prove that Europe can innovate while America standardizes.
