Hermann Tempel

Dr. Hermann Tempel, Acting Department Head of Functional Materials and Components at Jülich Research Centre, Germany, is a leading researcher in advanced electrochemical energy systems. Affiliated with the Institute of Energy Technologies (IET), specifically the Fundamentals of Electrochemistry (IET-1) department, he focuses on next-generation battery and electrolysis technologies.

His research explores

• solid-state batteries
• post-lithium chemistries (sodium-, aluminum-ion)
• CO2, wastewater, and alkaline water electrolysis
• nanoscale material properties

with emphasis on industrial scalability and technoeconomic viability.

Recent publications highlight trends in

• 3D carbon fiber interlayers for metal anodes
• high-entropy halide battery materials
• CO2 electroreduction catalysts and systems
• solid-state electrolyte microstructural optimization

via advanced electrochemical modeling, operando microscopy, and industrial process engineering.

His work addresses critical challenges in energy storage and conversion, particularly through

• in situ characterization techniques
• double-layer capacitance analysis
• solid electrolyte interphase (SEI) engineering
• electrochemical system design

to enable sustainable energy technologies.
