Modeling Acoustic Attenuation, Sound Velocity and Wave Propagation in Lithium‐Ion Batteries via a Transfer Matrix

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
“A simple 1D transfer matrix model of a battery is introduced and parametrized using harvested individual cell components at 0 % and 100 % SoC. This model allows for the calculation of group velocity and attenuation. The results of the model show good agreement with measured values, highlighting increased attenuation and group velocity at the ...

Chemical Prelithiation of Silicon Powder and its Role as Anode Material for All‐Solid‐State Batteries

open access: yesBatteries &Supercaps, EarlyView.
This article explores a carrier‐type approach for the chemical prelithiation of silicon (Si) powder and investigates the integration of prelithiated silicon (LixSi) as electrolyte‐free anode in sulfide‐based all‐solid‐state batteries. In comparison to a Si anode, the LixSi anodes showed improved cycle stability at 2 C, but revealed kinetic limitations ...

Archaeometric Analyses of Medieval Pottery From the Lower Danube Region, Romania

open access: yesChemPlusChem, Accepted Article.
This paper discusses the pottery manufacturing in the Lower Danube region during the Early Medieval period. Optical Microscopy (OM), Particle Induced X‐ray Emission (PIXE) and X‐ray Diffraction (XRD) were performed on thirty‐two ceramic shards unearthed at Pantelimonu de Sus, Romania, dated to the 8th‐10th c. AD. The petrographic observations showed an
