ProLogium, a leader in solid-state battery R&D and mass production, and OPmobility, a world leader in sustainable mobility and a technology partner to mobility players worldwide, have signed a Memorandum of Understanding (MoU). The Parties intend to discuss potential cooperation on integrating ProLogium solid-state battery cells into battery modules and/or packs jointly developed for vehicle applications, aiming to deliver a system-level solution that meets the rapidly growing demand of the global EV market.
Under the MoU, the Parties will discuss and evaluate a potential collaboration for the joint development and integration of solid-state battery cells into battery modules and/or packs for electric vehicles, to enhance competitiveness in the EV industry. Any discussions will be conducted within the framework of applicable competition laws.
In the first phase, ProLogium will provide solid-state battery cells to OPmobility for electrical performance testing in accordance with testing protocols agreed by ProLogium in advance. 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 OEMs for future EV platforms.
By aligning on common test protocols and engineering workflows, the collaboration is designed to accelerate system-level integration evaluation and engineering convergence, helping both Parties identify key parameters and challenges earlier and improve future OEM engagement efficiency.
To address the EV market’s core needs—range, fast charge, and climate-resilient reliability—ProLogium has disclosed key Superfluidized All Inorganic Solid-state Lithium Ceramic Battery performance metrics, including volumetric energy density of 900 Wh/L and gravimetric energy density of 380 Wh/kg, as well as fast charging from 5% to 80% in about 6.4 minutes. In durability and use-case performance, cycle life exceeds 1,200 cycles, and discharge at -20°C maintains over 95% performance. Through the cooperation discussions with OPmobility, the Parties will explore and validate how these cell-level advantages can be engineered and verified at module/pack level—supporting more efficient OEM evaluation and accelerating the path toward productizable, EV-ready integrated solutions.
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.”
Youssef Souiba, Executive Vice President, President of OPmobility’s C Power Business Group said: “Working with an established leader in the field of solid 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 technologies portfolio and its customer reach. It illustrates our capacity to partner with the right partners to innovate and contribute to the development of a more efficient and more sustainable mobility ecosystem.”
