The study investigated the aging behavior of battery cells under realistic vehicle load profiles and compared it to aging under constant laboratory cycling—while maintaining identical average discharge power and charging behavior. The results show that constant cycling leads to significantly stronger degradation, particularly in terms of increased loss of lithium… [read more]

In a recent study published in the Journal of The Electrochemical Society, Jonas Dickmanns and Lennart Reuter from the Chair of Technical Electrochemistry at TUM investigated how the formation process and the development of the solid electrolyte interphase (SEI) affect the structure and ionic transport properties of porous graphite electrodes in lithium-ion batteries… [read more]

In a recent study published in the Journal of The Electrochemical Society, the Chair of Technical Electrochemistry at TUM presents a detailed breakdown of the temperature-dependent chemical and electrochemical oxidation of the electrolyte, and its connection to key aging mechanisms such as LiPF₆ salt decomposition and transition metal dissolution from a… [read more]

In a recent study published in ACS Applied Materials & Interfaces, researchers from the Chair of Technical Electrochemistry at TUM present a novel operando X-ray photoelectron spectroscopy (XPS) setup to investigate the electrochemical stability of composite cathodes in all-solid-state batteries (ASSBs). The team examined the interface between a Ni-rich layered oxide… [read more]

In a recent study published in the Journal of Materials Chemistry A, an international research team investigates sodium-ion diffusion in NASICON-based solid-state electrolytes — promising candidates for next-generation solid-state batteries. Using quasielastic neutron scattering (QENS) and X-ray diffraction (XRD), the researchers identify two distinct Na⁺ diffusion… [read more]

In a recent publication in the Journal of The Electrochemical Society, the Chair of Technical Electrochemistry at TUM presents a systematic investigation of lithium diffusion in highly oriented pyrolytic graphite (HOPG). Based on time- and temperature-dependent measurements, the researchers determined the diffusion coefficient of the LiC₆ phase and showed that the… [read more]
