Talk on the determination of ageing phenomena in nickel-rich cathode active materials for lithium-ion batteries by Prof. Hubert Gasteiger at the Stanford StorageX Symposium

In the talk, Prof. Hubert Gasteiger presents the latest research results from his Chair for Technical Electrochemistry (TEC) on the determination of aging phenomena in nickel-rich cathode active materials.

New publication from the field of solid state electrolyte research

Characterization and Quantification of Depletion and Accumulation Layers in Solid‐State Li+‐Conducting Electrolytes Using In Situ Spectroscopic Ellipsometry / Leon Katzenmeier, Leif Carstensen, Simon J. Schaper, Peter Müller-Buschbaum, and Aliaksandr S. Bandarenka / Advanced Materials (2021): 2100585 - DOI

New publication of the Chair of Electrical Energy Storage (EES) in the Journal of the Electrochemical Society

Thorough validation of the ECD-3-nano dilatometry cell and reliable data on the expansion of graphite and NMCs with different nickel contents. Comparison of XRD data of crystral structure changes of NCMs and electrode expansion reveals limited correlation between the two.

Two new publications from the field of cell diagnostics - investigation of LMR-NCM and NCA cathode active materials in multilayer lithium-ion cells

The successful collaboration among the Chair of Technical Electrochemistry (TEC), the Institute for Machine Tools and Industrial Management (iwb), and the Institute for Electrical Energy Storage Technology (EES) within the projects ExZellTUM II (grant no.: 03XP0081) und ExZellTUM III (grant no.: 03XP0255) supported by the German Federal Ministry of Education and…

Scientists at the Technical University of Munich (TUM) have developed a new cell design for lithium-ion batteries for material characterisation

The "battery with windows" makes it possible to measure the lithium concentration within an electrode as a function of depth during charging and discharging with the help of neutrons. The new technique can help clarify reaction mechanisms in batteries and understand ageing phenomena.

New publication from the field of solid state electrolyte parametrisation

The paper reports investigations of the formation of space charge layers at different electrode polarisations using impedance spectroscopy. Which are analysed with a physical equivalent circuit model describing the response of the solid/solid interfaces under blocking conditions.
