ProLogium Technology and the French Alternative Energies and Atomic Energy Commission (CEA) have formed a technical partnership aimed at developing a removable, recyclable solid-state battery module. Since November 2024, the teams have collaborated on a “Design-for-Disassembly” structure that merges high energy density with a modular layout engineered for straightforward cell replacement. This design focuses on three sustainability criteria—reparability, recyclability and reusability—while preserving compactness and performance.
CEA contributes its expertise in module design, rapid prototyping and validation testing, leveraging decades of engineering research. ProLogium brings its Superfluidized all-inorganic solid-state lithium ceramic cells, which are noted for high energy density, intrinsic safety, ultra-fast charging capability and reliable operation at low temperatures. A full-scale mock-up of the automotive-oriented module is scheduled for public display at IAA Mobility 2025 in Munich from September 9 to 11.
Traditional liquid-electrolyte battery packs have trended toward closed architectures—such as Cell-to-Pack (CTP) and Cell-to-Chassis (CTC)—to boost pack-level energy density. These approaches, however, can compromise safety margins and hinder module-level repair or recycling, since a single faulty cell may require shredding an entire module. In contrast, the new design integrates non-welded connections and easily accessible cell holders, enabling individual cells to be swapped out without dismantling the entire pack. This not only reduces electronic waste and repair time but also lowers lifecycle costs.
By embracing disassembly principles, the partnership directly addresses challenges in battery circularity and supports Europe’s objective of regional autonomy in battery manufacturing. The modular architecture simplifies recovery of cell components for recycling and reuse, aligning with circular economy goals and enhancing the resilience of local supply chains. This collaboration is expected to bolster Europe’s leadership in solid-state battery research, contributing to strategic targets in industrial autonomy, carbon neutrality and sustainable energy transitions.
