White papers, environment reports and studies

The brochure examines the role of battery startups in an international context and categorizes their activities along the battery value chain. It highlights where young companies are driving technological innovation, identifies the challenges they face - particularly in financing and industrial scaling - and draws conclusions for Europe.

The “Modular Lifecycle Tool” provides a standardized framework for comparing lithium-ion battery recycling processes in terms of costs and CO₂ emissions and for evaluating different technological scenarios.

This white paper examines two closely related but often overlooked aspects of battery development: the formulation of the liquid electrolyte and the electrolyte filling process. It demonstrates how electrolyte chemistry directly influences process design and how next-generation battery systems pose challenges for the standardization of the filling process.

Lithium is an indispensable raw material for the production of modern batteries used in electric cars, smartphones, and laptops. In its latest white paper, “Lithium as a Battery Raw Material,” Fraunhofer FFB examines global lithium deposits and industrial processes for lithium extraction, highlights ecological impacts, and identifies potential for sustainable production and recycling strategies

Fraunhofer FFB, in collaboration with the PEM Chair at RWTH Aachen University, PEM Motion, and Capgemini, has published a white paper as part of the “Battery Cell Technology Cluster” explaining why process simulation is a strategic tool for optimizing battery cell production.

Together with the PEM Department of RWTH Aachen University, the Fraunhofer FFB has published a white paper on strategies and resources for an efficient and successful start-up of a gigafactory for battery cell production. The white paper outlines the organisational and technical hurdles associated with the ramp-up of a gigafactory and provides insights into how they can be overcome and the ramp-up process can be effectively managed.

The white paper by Fraunhofer FFB and Accenture focuses on digital solutions. For the study, 143 battery and digitalisation experts from mainly European and North American companies were surveyed in two stages. Firstly, the experts identified particularly effective use cases for digital solutions in battery production. These cases were integrated into a model of a battery factory with a capacity of 40 gigawatt hours, which the experts used to calculate and assess potential savings for each use case and production step.

The exponentially growing demand for battery cells, which are a key component for electromobility and the storage of renewable energy, can only be met if production is ramped up over the next few years. However, the construction of a gigafactory poses particular challenges for factory planning. To reduce risks and simplify commissioning, Metroplan and Fraunhofer FFB have developed a set of methods for planning and realising battery factories in line with requirements.

The Fraunhofer FFB environment report deals with sodium-ion batteries as an alternative battery technology. The researchers analyse the technological properties of the battery as well as the activities in research and industry relating to this technology - starting with material production and cell production through to the development of user markets. The environment report was produced as part of the overall "FoFeBat" project funded by the BMBF.

In the white paper, Fraunhofer FFB researchers show how the use of so-called "mini- and macro-environments" can reduce energy and operating costs in battery cell production, thereby creating great potential for competitive battery production in Germany and Europe.
