The EV arm of Ampere (formerly part of Renault Group) has entered a Joint Development Agreement with Stratus Materials Inc. to evaluate its innovative cobalt-free LXMO™ cathode chemistry for next-generation electric vehicles. The move is part of Ampere’s evolving battery roadmap—which follows high-density NMC cells and more cost-effective LFP cells—with the aim of delivering high energy, lower cost and more sustainable battery packs.
Stratus’ LXMO™ (Lithium X Manganese Oxide) material promises energy densities comparable to NMC technologies while mirroring the cost and safety profile of LFP batteries. Testing of the material will take place at Ampere’s new Battery Cell Innovation Lab in Lardy, France, where the partners will assess performance in EV-format cells. By embracing a cobalt-free approach, Ampere aims to reduce reliance on critical mineral supply chains and gain a competitive edge in battery design, while supporting longer range, enhanced safety and affordability in its future vehicle lineup.
