Swiss battery start-up BTRY AG has raised €4.9 million in an oversubscribed Seed spherical for its ultra-thin solid-state batteries reportedly able to combining quick charging, excessive temperature stability, and intrinsic security inside an especially skinny format.
The spherical was led by Redstone VC, with participation from Bloomhaus Ventures, Linear Capital, Kickfund, Kick Basis, and the CustomCells founders Leopold König and Torge Thönnessen as new traders. Present traders HTGF (Excessive-Tech Gründerfonds) and Zürcher Kantonalbank (ZKB) renewed their dedication.
“The oversubscribed spherical confirms sturdy investor confidence from skilled DeepTech and industrial backers. Working intently with this worldwide consortium will allow us to remodel world-class analysis right into a scalable product,” stated Dr Moritz Futscher, CEO and co-founder of BTRY AG.
Different current EU-Startups stories spotlight exercise throughout the worth chain: Estonia’s Jälle Applied sciences raised €2 million to advance battery-recycling and up-cycling supplies; Sweden’s DREV yesterday secured €2.8 million to scale contamination-control options for battery-manufacturing amenities; and Germany’s Terra One obtained €150 million to broaden grid-scale storage capability.
Whereas these initiatives goal recycling, manufacturing effectivity, and large-scale storage respectively, BTRY AG’s work on compact, fast-charging solid-state cells addresses the alternative finish of the spectrum – powering miniaturised sensors, logistics tags, and wearables.
Not one of the comparable 2025 EU-Startups fundings originated in Switzerland, making BTRY a particular nationwide contributor inside Europe’s broader push towards next-generation battery applied sciences.
“Potential prospects are prepared with their next-generation options, like lively badges in logistics. What they want is a small, highly effective, and secure battery – precisely what BTRY gives. We imagine the corporate has not solely the potential however the proof to set a brand new normal for high-performance vitality storage and are excited to assist its journey towards industrial scale,” stated Mohamed Foulser, Funding Director at Redstone VC.
Based in 2023, BTRY AG is a DeepTech spin-off from Empa and ETH Zurich creating ultra-thin solid-state lithium-ion batteries that allegedly function safely at excessive temperatures, allow ultra-fast charging, and have an exceptionally skinny kind issue for next-generation units.
The corporate has grown right into a 14-person group combining deep battery experience, industrial scale-up expertise, and robust enterprise acumen.
BTRY’s mission is to impress purposes beforehand restricted by the battery similar to lively logistics tags, high-temperature industrial sensors, MedTech purposes, and light-weight client electronics.
They energy next-generation units similar to linked labels, wi-fi sensors, and wearables – purposes the place typical batteries couldn’t match or endure.
“BTRY is an ideal instance of Swiss DeepTech at its greatest – science-driven, daring, and globally related. The founding group combines deep scientific experience with entrepreneurial grit. Their mixture of fabric innovation and industrial scalability makes them a frontrunner in Europe’s subsequent technology of battery firms,” stated Pascal Stürchler, CEO at Bloomhaus Ventures.
By making use of solid-state expertise from semiconductor manufacturing to battery manufacturing, BTRY says their expertise represents a leap within the international development towards thinner, safer, and longer-lasting batteries that allow extra dependable, compact, and linked units.
Based on the corporate, the batteries function safely at temperatures as much as 150 °C, the place typical cells fail, swell, or catch hearth. Beginning at simply 0.1 mm thickness, they cost inside one minute, straight powering wi-fi transmissions with out extra capacitors.
In contrast to large-scale vitality storage for electrical autos and grids, BTRY powers next-generation options similar to good linked labels, high-temperature industrial sensors, and light-weight client electronics. For these high-value purposes, miniaturisation and longevity of the facility provide matter most.
BTRY’s manufacturing method additionally achieves excessive sustainability requirements with its solvent-free manufacturing and low materials waste.
“Asia has been main the best way in battery manufacturing for many years, however improvements like BTRY’s present that Europe can compete by superior supplies and precision processes. We see sturdy potential for collaboration between Asian manufacturing experience and BTRY’s pioneering solid-state expertise,” stated Tianyi Zhou, Principal at Linear Capital.
BTRY will use the funds to scale manufacturing to industrial roll-to-roll manufacturing, remodeling its thin-film batteries into market-ready merchandise. The corporate is now specializing in establishing its manufacturing set-up, advancing industrial processes, and securing offtake agreements for integration in next-generation units.
