BTRY AG is a young Swiss deep-tech startup founded in 2023 as a spin-off of ETH-Zurich and Empa developing an innovative, sustainable and reliable all-solid-state battery. BTRY's innovation lies in its vacuum-based process, which enables the production of thin-film batteries with a thickness of only a few micrometers.

BTRY can produce solid-state batteries that are fundamentally different from traditional lithium-ion batteries. These batteries can charge and discharge in less than five minutes, have higher energy density (up to 800 Wh/L), can operate from -40 to 150°C, are thinner than a human hair (< 50 ?m), and cannot catch fire or explode. These features are unique and fill a clear gap in the market.

Currently, BTRY is producing and developing its batteries on a laboratory scale in Zurich. However, BTRY's goal is to rapidly bring the technology to scale for European production. Under a current joint development agreement with one of the world's largest machine manufacturers, BTRY plans to produce millions of batteries per year in its first factory line by 2029.

Bio

Industrial Engineer (ISAE-SUPMECA) by training, I made a pivot to materials science to study functional materials playing a role in the energy transition. I first obtained a PhD in materials chemistry at the University of Paris-Saclay by studying lithiated entropy-stabilized oxides. Then I had the opportunity to join Empa in 2021 within an Innosuisse project (Empa/Oerlikon) to study and develop the deposition of thin-film solid-state electrolytes by PVD techniques.

In December 2024 I joined the start-up company BTRY AG (spin-off Empa/ETH) as R&D Laboratory Manager to build up an independent in-house laboratory and to drive innovation and product development through R&D and customer-oriented projects.
