Objective
BTRY is a Swiss deep-tech startup developing and manufacturing next-generation thin-film solid-state batteries for IoT, MedTech, and consumer electronics. Founded in 2023, as a spinoff from ETH Zürich and Empa, BTRY is translating a decade of academic breakthroughs into an industrially scalable product.
Today's electronics manufacturers are forced to combine bulky batteries and supercapacitors to meet the power demands of wireless devices. BTRY eliminates this trade-off. The proprietary vacuum-coating process produces ultra-thin (< 25 µm), all-solid-state batteries that uniquely combine high energy density with exceptional peak power, operating reliably from −40°C to 150°C, all in a non-flammable, flexible form factor.
Unlike conventional battery manufacturing, BTRY's solvent-free process uses established roll-to-roll equipment from the semiconductor industry, making it inherently scalable and cost-competitive. With high gross margins and a large potential customer base, the business case is compelling.
BTRY has validated its technology across four production platforms, secured commercial agreements with leading electronics companies, and closed a €4.9 million seed round in 2025. With blended EIC Accelerator support, BTRY will advance to TRL 8 and construct Europe's first thin-film solid-state battery factory - producing millions of batteries for the global market.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
