What They Do
BTRY AG develops ultra-thin, fast-charging thin-film solid-state batteries characterized by a solid electrolyte layer instead of a liquid, flammable electrolyte (source: btry.ch). This technology enables an extremely low profile of about 0.1 mm, high safety, and operation across a wide temperature range from approximately -40 °C to 150 °C, making it especially suitable for demanding applications in IoT, medical technology, semiconductor industry, and consumer electronics (source: btry.ch). The batteries can be charged and discharged in around one minute, making them ideal for devices requiring short, high-power energy pulses (source: btry.ch). Manufacturing is solvent-free and uses a vacuum-based process that reduces the number of steps by about 60% compared to conventional lithium-ion batteries and is based on standard semiconductor production lines (source: btry.ch).
Projects & Track Record
Since 2022, BTRY has made remarkable progress from the lab phase to industrial production. Starting with 1 mm × 3 mm proof-of-concept cells at Empa, the company produced its first batteries on flexible metal foil substrates in 2023, followed by 10 cm × 10 cm batteries in March 2024. In August 2024, the first cells were manufactured on an industrial production line based on semiconductor manufacturing technology (source: btry.ch). Collaboration with InsightSilica since September 2026 focuses on developing solid-state batteries for the semiconductor industry, featuring batteries under 1 mm thick and operating temperatures up to 150 °C (source: btry.ch). As a spin-off from Empa and ETH Zurich, BTRY benefits from strong institutional partnerships and concentrates on scaling production at its Dübendorf site (source: btry.ch).
Recent Developments
BTRY secured an oversubscribed seed funding round of 5.7 million US dollars to accelerate the industrialization of its thin-film solid-state batteries (source: btry.ch). Additionally, the company received a non-dilutive grant of 2.2 million euros from the European Innovation Council Accelerator to support scaling production (source: btry.ch). In the 2026 Venturelab Top100 Swiss Startups ranking, BTRY placed eighth, marking its second consecutive year in the top ten (source: btry.ch). Participation in major technology and industry events such as MWC Barcelona/4YFN and Hannover Messe highlights its active market presence (source: btry.ch).
Working There
BTRY employs specialists in materials science, battery and product development, manufacturing scale-up, and business development (source: btry.ch). The workplaces are located on the Empa campus in Dübendorf, where research and development are closely integrated (source: btry.ch). Due to the company’s size, employees often work cross-functionally and support development from the lab phase through pilot production (source: btry.ch). The corporate culture is characterized by a strong research-to-industry focus and the use of established semiconductor manufacturing methods to commercialize a novel battery technology (source: btry.ch). While no formal employee benefits or compensation program is publicly documented, proximity to Empa and ETH Zurich offers an attractive innovation environment (source: btry.ch).
