PSI – Laboratory for Battery Science

The PSI Laboratory for Battery Science, established 2025, is part of the Center for Energy and Environment Sciences at the Paul Scherrer Institute.

Fundamental research on battery materials and their characterization is pursued at PSI since three decades, resulting in a unique research environment, with a strong focus on operando characterization and mechanistic understanding, building up on this firm basis to develop innovative technology platforms that directly benefit society, with an emphasis on new collaborations and fresh approaches. Three groups have activities in rechargeable batteries at PSI: Battery Electrodes & Cells, Battery Mechanisms & Materials Design and Battery Materials & Diagnostics.

PSI has availability for cell testing and advanced electrochemical characterization, as well as a set of advanced post-mortem and operando material-characterization techniques, specifically dedicated to battery materials, electrodes, electrolytes and cells. Number of in-house-developed cells and setups are available for operando measurements using variety of analytical methods, including at large scale facilities.

The battery research at PSI spans from materials design and synthesis to the cell-level characterization of the full range of battery components: active and passive materials, electrodes, separators, liquid and solid electrolytes, and their interphases.
