Materials for Energy Conversion


Mission We strive to solve industry-relevant challenges for sustainable energy conversion and storage technologies through materials and device innovation.

Expertise Our laboratory possesses strong competencies in the synthesis and processing of functional electronic and ion conducting materials, the characterization of their structural, electronic, ionic and thermal transport properties, as well as their integration and performance assessment in operational devices.

Research Our research aims at developing fundamental knowledge through experiment and modeling enabling new materials and processes that improve device performance, stability, cost, and sustainability. We focus on the following application-driven topics: batteries for short-term energy storage and electrochemical fuels for long-term energy storage.
