Early detection of faults in lithium-ion batteries is essential to ensure the safety, reliability, and longevity of battery electric vehicles (BEVs). Fault mechanisms such as internal short circuits, lithium plating, electrolyte decomposition, and mechanical defects originate at the cell level and often develop unnoticed before manifesting as pack-level degradation or system failure. Detecting anomalies during […]

This work aims to accurately map the internal temperature during cell operation using various implementation ideas. The investigations are carried out on modified cylindrical cells, in the centre cavity of which a temperature sensor has been integrated by opening the cell in a glove box and resealing it using a two-component adhesive, which serves as […]

In this study, we found optimizing the ZIF-8 content is an effective strategy to induce the soggy-sand effect while mitigating surface roughness of the membrane. (The optimal composition: 30 vol% ZIF-8) Three Li⁺ transport pathways coexist: conduction through the polymer matrix, migration along the continuous pathways between interconnected ZIF-8 particles, and penetration through the ZIF-8 […]

Sodium-ion batteries (SIB) represent a competitive alternative to lithium-ion batteries, especially for large-scale electric energy storage to stabilize the power grid. Their suitability is underlined by lower costs, environmental benignity and higher natural abundance of sodium resources. Common cathode materials for SIBs are layered transition metal oxides like Na2/3Fe1/2MnO2 and oxoanion compounds like NaFePO4. Prussian […]

Electrochemical Impedance Spectroscopy (EIS) is a method used for estimating battery states (SoX) through the measurement of battery impedance, allowing rapid and accurate monitoring of Li-ion batteries (LIBs). Safe operation of LIBs is critical to optimizing battery performance across all application use cases. The practical application of EIS, on both Electric Vehicles (EVs) and Battery […]

Accurate modeling of lithium transport in polycrystalline cathodes is essential for reliable battery simulations. However, reported solid-state diffusion coefficients often vary widely due to particle-scale effects. In this work, we investigate the influence of secondary particle size on reaction kinetics and solidstate transport in NMC622 cathodes by combining particle-size-fractioned model electrode experiments with single-particle electrochemistry […]
