Development of a data transparency platform for sustainable battery material value chains
As the production of batteries for electromobility has a significant environmental impact, the European Union is currently developing a new Battery Regulation. It is expected that a declaration of the carbon footprint of batteries will be mandatory within the EU from July 2024 on. Thus, a data platform including also Life Cycle Assessment (LCA) information […]

Data to Value in the Recycling of Lithium-Ion Batteries
Batteries are highly integrated products composed of mixed materials that are highly affected by energy-intensive production and processing, security of supply, and raw material criticality. Due to the energy-intensive production and processing of battery raw materials, valuable materials with high qualities are concentrated in batteries. With the steadily increasing demand for batteries, more and more […]
Failure Modes and Effects Analysis used for the identification of critical loads applied to second-life mobile and stationary applications
The use of Lithium-ion batteries in second-life applications is becoming increasingly widespread. A battery extracted from an electric vehicle can be used in a wide range of applications, both stationary (e.g. energy storage system connected to a renewable energy source) and mobile (e.g. warehouse´s industrial vehicle). In order to ensure a successful transition from first […]
Non-invasive application of polymer optical fiber sensors for high fidelity operando monitoring of strain and temperature in Li-ion batteries
Successful assessment of the battery degradation mechanism and safety conditions may be enabled through monitoring dynamic thermal, chemical, and mechanical status of a cell during cycling. In this regard, the convergence of fiber optic sensing with lithium-ion batteries holds great promise for observing key cell parameters in real time, allowing for identifying crucial factors involved […]
Determinants of Ramp-up Management in Battery cell Factories
In recent years, the number of announced battery cell gigafactories in Europe is increasing with a rapid pace. Both new entrants and incumbent firms are among the players who are planning and discussing their high outputs of Lithium-Ion battery cells in the near future. However, either the copy exactly strategy or the factory blueprints from […]
