OPmobility and ProLogium sign MoU to develop next-generation solid‑state battery packs for mobility

OPmobility and ProLogium, a leader in solid-state battery R&D and mass production, have signed a Memorandum of Understanding (MoU) to discuss a collaboration for the joint development and integration of solid-state battery cells into battery modules and packs for electric vehicles. Solid-state batteries are emerging as a critical enabler for the next generation of electric mobility, offering meaningful gains in driving range, charging performance and safety.

Under this MoU, ProLogium will provide solid-state battery cells to OPmobility for electrical performance testing. OPmobility will be responsible for the design, development and manufacturing of battery modules utilizing the solid-state battery cells provided by ProLogium. The shared objective is to jointly develop a battery module solution that can be adopted by Original Equipment Manufacturers (OEM) for future Electric Vehicle (EV) platforms.

Through this cooperation, the partners will explore and validate how these cell-level advantages can be engineered and verified at the module and pack level – providing OEMs with better performance evaluation and accelerating the path toward EV-ready integrated solutions.

Félicie Burelle, Chief Executive Officer of OPmobility, declared: “This partnership is a new milestone in our ambition to accelerate the growth of our electrification product line, a few months after announcing a major award to provide battery packs to a global OEM for passenger cars in the U.S. It illustrates our capacity to collaborate with the right partners to innovate and contribute to the development of a more efficient and more sustainable mobility ecosystem.”

Youssef Souiba, Executive Vice President, President of OPmobility’s C-Power Business Group, stated: “Working with an established leader in the field of solid-state batteries such as ProLogium strengthens OPmobility’s ability to anticipate the needs of global automotive manufacturers and supports the Group’s ambition to expand its technology portfolio and its customer reach. This partnership is fully aligned with our strategy to design and assemble battery packs, regardless of the cell technology used.”

Vincent Yang, Founder and CEO of ProLogium, said: “For solid-state batteries to be truly adopted by the market, the key is system integration and validation—from cells to modules and packs. This MoU with OPmobility starts from pragmatic performance testing and module development under aligned test protocols and engineering workflows, clarifying the critical path for vehicle integration. Our shared goal is an OEM-adoptable module solution, and we will continue to advance discussions within a compliant framework.”
