During the 12th Batterieforum Deutschland, Rebecca Wilhelm and Leonhard Reinschlüssel were awarded with the 3rd and 1st place prizes for their respective posters. From the 24th to 26th of January 2024, the Kompetenznetzwerk Lithium-Ion Batterien (KLiB) organized the 12th Batterieforum Deutschland at the Ritz-Carlton in Berlin and virtually, in collaboration with the Federal Ministry of Education… [weiterlesen]

In this paper, an ML-enhanced testing procedure for li-ion batteries is proposed, which increases the efficiency of cycle life testing by stopping the cycling of a subset of batteries and predicting their end of lifes instead. Based on aging features and the Kennard-Stone algorithm, a suitable subset of batteries is selected, whose future aging trajectory can be predicted with high accuracy. The… [weiterlesen]

Here, we show that the voltage hold and the voltage decay methods deliver comparable results when determining the differential capacity with an incremental capacity analysis (ICA) instead of a single pulse for the voltage decay method. Both methods presented a good agreement for high temperatures and high SoC cases. In addition, with the end of charge point and end of discharge point slippage… [weiterlesen]

Die Forschungsgruppe „Energieeffiziente Abwasserbehandlung“ beschäftigt sich insbesondere mit innovativen Verfahren zur Steigerung der Energieeffizienz und zur Maximierung der Energierückgewinnung aus den behandelten Reststoffen, beispielsweise in Form von energiereichem Biogas. Für ein Forschungsvorhaben werden ab sofort zunächst zeitlich befristet für 3 Jahre zwei Wissenschaftliche… [weiterlesen]
