In contrast to conventional lithium-ion batteries, which are limited by slow charging times and temperature sensitivity, BTRY uses an innovative solid-state technology. This is based on the stacking of thin-film cells using a semiconductor manufacturing process, which is a high-precision and solvent-free process. The resulting batteries not only offer fast charging times and high reliability at extreme temperatures, but also significantly improve economic efficiency and environmental compatibility.

BTRY initially plans to use the batteries in the IoT market, where the demand for batteries for remote-controlled sensors is growing strongly, driven by Industry 4.0 technologies. This market is expected to reach a volume of USD 240 million by 2030. In the long term, the company also plans to enter the high-end medical and consumer electronics market, which is expected to exceed a volume of USD 2 billion by 2030.

The investment of 150,000 Swiss francs by Venture Kick will be used to demonstrate scalability through production on pilot lines, further improve the product offering and accelerate the market launch. This will strengthen the basis for a planned seed financing round in the third quarter of 2025.
CEO Dr. Moritz Futscher and CTO Dr. Abdessalem Aribia founded BTRY together with Dr. Yaroslav Romanyuk as scientific advisor in 2023 as a spin-off of Empa and ETH Zurich.
“Venture Kick has been with us from the very beginning,” says Moritz Futscher, CEO of BTRY. “This support has been crucial for our growth and has helped us to grow from a scientific from a scientific project to a successful company. We look forward to continuing this collaboration.
