Perovskites are gaining attention as anode materials in lithium-ion battery research due to their advantageous crystal structure and tunable properties. The perovskite lattice, with a general formula of ABX3, provides a flexible and stable framework that allows for effective lithium-ion diffusion and enhanced charge storage capacity. Compared to traditional anode materials, perovskites offer high ionic […]

The battery resistance and aging processes are a function of the temperature, state of charge (SoC), and current profiles a battery experiences over its lifetime. Consequently, it seems intuitive that the same dependencies apply to the extracted parameters of an equivalent circuit model. Therefore, this study aims to deepen the understanding of the factors influencing […]

Since the electrochemical impedance spectroscopy (EIS) is a powerful tool to estimate the state of a lithium-ion battery cell, its implementation in electric vehicles is driven forward in many research activities. Within this context, we present results on a distributed system for single cell impedance measurements within a larger battery unit. The system is characterized […]

As the first commercial sodium-ion-batteries (SIBs) are available for purchase, it is possible to investigate material composition. Gaining an insight into the material composition of these SIBs is of interest not only for the classification of possible safety risks and hazards, but also in regards to recycling. Herein we report the preliminary investigations of the […]

The lifetime of Li-ion Batteries (LIB) depends on the reversible amount of Li ions and electrons (= active Li), defining Li inventory and cell capacity. Active Li loss (ALL) occurs at the negative electrode (= anode) predominantly via electrolyte reduction and formation of the solid electrolyte interphase (SEI). Nevertheless, given interference of the cathode, anode […]

A fast and accurate lifetime estimation of a lithium-ion batteries is decisive for planning a sustainable technological future. For this purpose, batteries are aged using the highest possible current rates in accelerated cyclic aging tests excluding test pauses. This strategy, however, can lead to electrolyte-motion-induced salt inhomogeneity (EMSI) [1], which disrupts the homogeneity of lithium […]

Recent years have witnessed an exponential increase in battery research, driven by the need to develop efficient and sustainable energy storage systems. One of the main tools in battery research is battery cycling experiments, providing insights into the performance, lifetime and quality of the battery. Due to the large variety of battery testing equipment and […]

The safety of the Li-ion battery is known to be a critical issue due to its high energy density and the high flammability of most of its components. Here we report on observations of significant gassing in large commercial Li-ion pouch cells during end-of-life (EoL) storage at supposedly ideal storage temperature, as well as the […]
