Holistic battery recycling requires processes rooted in various disciplines like electrical engineering, particle technology, chemistry, and metallurgy. Depending on the goal of the recycling process or the prioritized products, the usage of individual processing steps and their sequence leads to various process chains. Furthermore, the reverse transformation from the battery back to suitable intermediates or […]

Abstract: The “Composite Battery Module” project aimed to reevaluate existing housing designs for battery modules in electric vehicles and to explore alternative construction methods using composite materials. The development of a prototype began with a general observation and characterization of a pouch cell, extending these findings to the module level, and encapsulating them in a […]

Electrochemical impedance spectroscopy (EIS) is a reliable and non-invasive measurement technique for the characterization of electrochemical systems, ranging from material and electrode level up to cells and systems. The impedance spectrum resulting from the measurement contains valuable information about properties and states of the electrochemical system, including the ongoing electrochemical processes [2, 3]. In practice, […]

Due to the strong growth of lithium-ion-batteries in recent years, the focus is increasingly moving to the safe operation of batteries. A particular driver here is the social acceptance of electromobility, which is strongly influenced by the safety of traction batteries. Besides efforts on the material level, securing the cells by intelligent battery management systems […]

The lithium ion battery (LIB) still suffers from capacity loss due to several aging mechanisms during cycling and storage. The electrolyte is not stable at the applied electrode potentials and forms passivating layers on the anode and cathode, the so-called solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI), respectively. These interphases consist of various […]

Lithium-ion battery degradation poses a significant obstacle to the widespread adoption of battery-powered technologies. Accurate aging models, relying on parameters derived from experiments, are essential to predict battery lifespan. However, traditional experimental methods are often time-consuming and expensive. This study proposes a novel two-stage experimental characterization method to efficiently estimate parameters for a semiempirical battery […]

It is expensive to test and train data-driven algorithms for detecting and predicting electrical faults in battery systems by solely relying on laboratory experiments. Acquiring battery data, including malfunctions, is a challenge. To address this, our simulation framework generates synthetic battery pack data that simulates real-world variations, such as production quality and environmental conditions. This […]
