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… [read more]

The article "Modeling Silicon-Dominant Anodes: Parametrization, Discussion and Validation of a Newman-Type Model" was published in November in the journal "Batteries". The authors are Axel Durdel, Sven Friedrich, Lukas Hüsken and Andreas Jossen. The article deals with the electrochemical modelling and parameterization of silicon-dominant anodes. The literature is… [read more]

The ECS Student Chapter Munich hosted a symposium on the topic “From Academia to Industry - Electrochemical Challenges at Different Scales“ on the 21st of September with more than 100 participants, including master’s students, PhD students, Postdocs, as well as Professors. The overarching question of this event was how academia and industry can collaborate more… [read more]

The study investigates the applicability of Newman and coworkers' exchange current density expression for modeling Li-ion battery materials, focusing on NCM 111. It finds that the kinetics align with the proposed theory at lower salt concentrations but deviate at higher concentrations, and that asymmetry in charging and discharging kinetics limits performance due to… [read more]
