Integration of an Expert System into the IT-Architecture of a Battery Production Plant Electromobility is one of the biggest leverages to achieve the goal of climate neutrality. The rising demand for electric vehicles leads to a rapid increase in the production capabilities of batteries in Germany. To cope with the rapid increase in production coupled […]

The production of lithium-ion batteries requires materials such as cobalt, graphite, lithium, manganese and nickel, with China controlling most of the resources and European countries having limited mining capacity for these raw materials. As a result, Europe’s lack of security of supply for key raw materials, such as lithium and cobalt, for the production of […]

Summary: Diehl Aerospace GmbH develops and produces emergency power systems and battery packs for aircrafts. Depending on certification requirements, nickel-cadmium- (NiCd), lithium cobalt oxide (LCO) or lithium iron phosphate (LFP) cells are used. They are monitored by an appropriate battery management system (BMS). Besides the functional safety, the determination of the remaining capacity, i.e. State […]

Whereas a lot of research is focusing on ageing detection and end of life prediction the problem of detecting safety critical states using field data still lacks profound knowledge. In state-of- the-art battery management systems (BMS) the compliance of limits for critical signals such as voltage, current or temperatures is supervised. Furthermore, the State of […]

This work implements a new patent-based analysis framework to gain a deeper insight into the individual production processes and their mutual interactions, in order to separate the technological developments within them e.g., active material and battery system patents, from the production-related process patents. This study aims to narrow the gap between implicit and explicit knowledge […]

Extensive characterization of new cell materials or changes in production methods can be a time-consuming process, often taking several months for well-established chemistries. Nevertheless, there is a growing interest among battery manufacturers in understanding the performance and impact of emerging cell materials and production methods in a more expedited manner to ensure safety and quality […]

Lithium plating (accumulation of metallic lithium) is a safety-critical phenomenon that occurs mainly during fast charging of lithium-ion batteries at cold temperatures. It is caused on the anode by the limited capability to absorb lithium ions at the desired rate. Reversible and irreversible plating can be accompanied by the formation of dendrites and lead to […]

State-of-the-art batteries most commonly used in everyday devices comprise lithium-ion batteries that afford a gravimetric energy density of up to 800 Wh kg-1, which in view of rising demands in electric vehicle applications may not be sufficient. Changing the positive active material to the more abundant and potentially environmentally friendly sulfur, the gravimetric energy density […]
