Simon Fleischmann

Dr. Simon Fleischmann is a group leader at the Nanoconfined Electrochemical Interfaces research group under the Karlsruhe Institute of Technology (KIT), with affiliation to the Helmholtz Institute Ulm (HIU). His work focuses on optimizing layered and two-dimensional materials for high-power electrochemical energy storage through structural and chemical tailoring of interlayer spaces.

• Key Research Areas: Ion intercalation, nanostructuring, pseudocapacitive charge storage, sustainable electrode materials, and advanced battery characterization.
• Notable Projects: NanoMatFutur-funded InfinBAT (2021–2026), DFG’s NanoconEC (2022–2025), and Daimler und Benz Stiftung-funded sodium-ion battery development.

His group employs soft chemistry synthesis to engineer nanoconfinement environments, enabling accelerated ion transport in layered materials. Research highlights include pseudocapacitive lithium intercalation in MoS₂, MXene-based heterostructures for ammonium ions, and novel strategies to mitigate degradation via interlayer functionalization.

Scientific Contributions:

• Developed cryogenic electron microscopy workflows for battery interface analysis.
• Elucidated defect evolution in carbon nanotubes during electrochemical cycling.
• Demonstrated unified electrolyte-electrode design for ion–solvent cointercalation.

Honors:

• NanoMatFutur Fellowship (BMBF).
• Postdoktorandenstipendium der Daimler und Benz Stiftung.

Team: Supervises a multidisciplinary team including doctoral students (Jaehoon Choi, Yoga Malik, etc.) and postdocs (Maciej Tobis, Mete Batuhan Durukan), collaborating with industry partners like Skeleton Technologies.
