A retired EV battery pack weighs about as much as a grand piano, contains roughly 10 kilograms of cobalt and nickel worth recovering, and is, depending on its state of health, anywhere between inert and quietly furious. Today, mostly, a person in protective gear takes it apart with hand tools. R3 Robotics, a Luxembourg startup that until recently went by Circu Li-ion, would like a robot to do that instead.
In February 2026 the company closed €20 million in combined financing, with €14 million of Series A equity co-led by HG Ventures and Suma Capital, plus €6 million in European grants [EIT Urban Mobility, Feb 2026]. The round also includes Oetker Collection, the European Innovation Council Fund, and existing backers BonVenture, FlixFounders and EIT Urban Mobility itself [Preqin, 2026].
The disassembly bottleneck
Europe has spent a decade subsidizing batteries into cars and is now arriving, on schedule, at the part of the lifecycle nobody put on a slide. End-of-life packs are stacking up faster than recyclers can process them, because the first physical step, taking the pack apart safely enough to feed a hydrometallurgical or pyrometallurgical line, is still mostly manual.
R3's wedge sits exactly there. Its systems combine 3D vision, adaptive motion planning and purpose-built robotic tooling to dismantle battery packs, e-drives and power electronics into component-level streams [R3ROBOTICS, retrieved 2026]. The company sells this as either Disassembly-as-a-Service at its own sites or Robotics-as-a-Service lines deployed at a customer's facility [R3ROBOTICS, retrieved 2026].
Why automating this step matters
The interesting claim is not that a robot can unscrew things. It is that consistent disassembly changes what comes out the other end. R3 says its process delivers greater than 98% repeatability, which is the kind of number a downstream recycler needs in order to plan around a feedstock rather than improvise around it [R3ROBOTICS, retrieved 2026].
A back of envelope: a mid-size EV battery pack weighs around 450 kg. If R3's automated line moves through one pack roughly every 30 minutes (a plausible target for a robotic cell, not a company-disclosed figure), a single line running two shifts processes on the order of 30 packs a day, or about 13.5 tons of battery mass. At European retired-pack volumes projected into the late 2020s, you would need dozens of such lines just to keep up with one country's flow. That is the business case, and it is why the company is selling lines, not just services.
R3 also claims up to 32% lower processing cost versus manual disassembly and up to 75% higher throughput [R3ROBOTICS, retrieved 2026]. Those are vendor figures and should be read as the upper bound of a marketing deck rather than an audited result.
The round and who wrote the check
Series A equity (Feb 2026) | 14 | M EUR
EU grants (Feb 2026) | 6 | M EUR
HG Ventures is the corporate venture arm of The Heritage Group, an industrials holding company with a long bench in materials and recycling. Suma Capital is a Barcelona-based growth investor with a climate infrastructure book. Between them, the syndicate is industrial rather than purely venture, which is the right shape of capital for a company that has to put hardware on factory floors.
The grant half of the round is doing real work too. €6 million from European programs is non-dilutive money that buys engineering runway without forcing a valuation conversation, and it signals that EU bodies see automated dismantling as strategic infrastructure rather than a startup curiosity.
Team and the KUKA signal
R3 was founded in 2021 by CEO Antoine Welter and CTO Xavier Kohll, who grew up together in Luxembourg [Silicon Luxembourg, retrieved 2026]. Welter's prior background is in strategy consulting and angel investing across Europe, Asia and Africa [Frontlines.io, retrieved 2026]. Kohll holds a doctorate [Chamber of Commerce Luxembourg, retrieved 2026].
The name that should make competitors pay attention is on the board. Peter Mohnen, former CEO of KUKA, the German industrial robotics manufacturer, has joined R3's advisory board [The AI Insider, Feb 2026]. Pulling a former KUKA chief into an EV-disassembly Series A is the kind of credentialing that helps when you are walking into an automotive OEM procurement meeting and asking them to trust your cell next to their pack line.

Customers and the Fortum proof point
R3 is working with Fortum Battery Recycling to deploy automated dismantling at industrial scale, and reports direct engagements with automotive OEMs feeding end-of-life battery systems through its centralized infrastructure [HG Ventures, retrieved 2026]. Fortum matters because it is one of the few European recyclers with a serious lithium-ion line already running, which means R3 is not selling into a market that has to be conjured into existence.
The rebrand from Circu Li-ion to R3 Robotics is consistent with this expansion: batteries are the wedge, but e-drives, power electronics and other high-value EV components are the larger surface area.
What could go wrong
The honest risks worth naming:
- Throughput variance. Battery packs are not standardized across OEMs. A robotic cell tuned for a VW MEB pack does not automatically handle a Stellantis or BYD pack, and retooling time is the silent killer of cell economics.
- Vendor metrics. The 32% cost reduction and 75% throughput figures are company-published and not independently audited [R3ROBOTICS, retrieved 2026]. The Fortum deployment will produce the first real third-party numbers.
- Capital intensity. Robotics-as-a-Service shifts capex onto R3's balance sheet. €14 million of equity is a serious Series A but a modest sum once you are financing multiple lines in the field.
The next twelve months
The milestones to watch are concrete: a second named recycler customer beyond Fortum, a first OEM willing to be named publicly, and any disclosed throughput number from a deployed line rather than a spec sheet. A Series B in 2027 looks likely if the Fortum site produces clean data.
The incumbent R3 has to beat is not another robotics startup. It is Redwood Materials, JB Straubel's Nevada-based recycling company, which has chosen the opposite strategy: take the whole pack, shred it, and recover materials at the back end with chemistry. Redwood's bet is that disassembly is not worth the trouble. R3's bet is that, in Europe, with traceability regulation tightening and second-life markets opening, the wrench beats the shredder. The next two years will tell which side of that argument the recyclers are willing to fund.
