The HELENA project continues to make significant strides in the development of cutting-edge solid-state battery technology. On June 4th and 5th, 2024, project partners gathered at the IFP Energies nouvelles facilities in Solaize, near Lyon, for the 5th General Assembly. This meeting provided a crucial opportunity to review progress, align strategies, and discuss the next steps in bringing halide-based solid-state batteries closer to industrial application.
The assembly featured a series of focused sessions covering key aspects of the project:
-
Project Coordination and Management: Overview of progress and administrative updates.
-
Battery EV and Aircraft Requirements: Discussion on performance specifications and industry needs.
-
Material Development and Optimization: Advances in materials for solid-state batteries.
-
Lab-Scale Battery Component Preparation and Cell Assembly: Progress in assembling battery prototypes.
-
Battery Cell Design and Pre-Industrial Scale-Up: Steps toward manufacturing readiness.
-
Testing, Aging, and Safety: Evaluation of battery performance under different conditions.
-
Multiscale-Multiphysics Battery Modelling: Computational approaches for battery optimization.
-
Life Cycle, Cost Assessment, and Recycling: Sustainability and economic viability studies.
-
Dissemination, Communication, and Exploitation: Strategies for increasing project visibility and impact.
A highlight of the event was the visit to the IFPEN facilities, where participants explored state-of-the-art research infrastructures supporting HELENA’s objectives.
A special thank you to IFP Energies nouvelles for hosting this pivotal event and to all our partners for their dedication and contributions. As we move forward, the HELENA project remains committed to pushing the boundaries of energy storage technology, paving the way for a more sustainable and electrified future.
