Invitation: Start-up Day - Fuel Cell & Battery Innovations

The ECS Student Chapter Munich is pleased to invite you to this year’s Start-up Day, focusing on innovations in fuel cell and battery technologies.

New Publication from the Chair of Electrical Energy Storage Technology: Degradation Analysis of Lithium-Ion Cells with Silicon-Dominant Anodes

In a recent study, the Chair of Electrical Energy Storage Technology at TUM investigates the nuances of voltage reconstruction in degradation mode analysis. The study examines various initial parameterizations and algorithm settings. By using T-cells with lithium metal reference electrodes, the fitted single-electrode potentials could be directly validated against…

New Publication by the Advanced Materials Group at FRM II on Lithium Loss Mechanisms in NCA||Si Cells

In a recent study, the Advanced Materials Group at FRM II demonstrates that during cyclic aging of NCA||Si cells, lithium is lost from the cathode and remains trapped in the silicon-rich anode. Operando neutron diffraction and prompt gamma activation analysis (PGAA) confirm the structural changes and lithium redistribution—providing important insights into degradation…

New Study from the Chair of Automotive Technology: Influence of Load Profiles on Impedance Relaxation Behavior in Lithium-Ion Batteries

In a recent publication in the Journal of Power Sources, the Chair of Automotive Technology at TUM analyzes the impedance relaxation behavior of lithium-ion cells following defined discharge procedures. The study investigates the impact of state of charge (SoC), depth of discharge (DoD), and realistic discharge profiles on impedance over relaxation periods of up to 46…

New Study from the Chair of Automotive Technology: Impedance-Based Early Detection of Thermal Runaway in Automotive Batteries

In a recent publication in eTransportation, the Chair of Automotive Technology at TUM presents a novel methodology for impedance-based early detection of thermal runaway (TR) and precise temperature estimation in large-format lithium-ion batteries—both at the cell and system level. The study focuses on realistic battery modules with parallel-connected cells, as used…
