Ampere in JV to explore the application of cobalt-free cathode technology for Renault Group’s next-generation electric vehicles
Ampere partners with Stratus Materials in a Joint Development Agreement (JDA) to explore innovative cobalt-free LXMOTM battery technology for future Renault Group EVs.
LXMOTM technology offers high energy density comparable to NMC batteries, with cost and abuse tolerance similar to LFP batteries.
This collaboration is part of Ampere’s strategy to develop next-generation batteries, following NMC and LFP technologies
Ampere, the EV and Software pure player from Renault Group has entered into a Joint Development Agreement (JDA) with Stratus Materials Inc., a leading developer of high energy cobalt-free LXMOTM cathode active materials (CAM) for advanced Li-Ion batteries. This JDA represents the first step to evaluate the relevance of inserting Stratus Material’s high energy cobalt-free LXMOTM into the Renault Group’s electric vehicle (EV) fleet and focuses on demonstrating the high performance of the material in EV-format battery cells. This new technology developed by Stratus Materials will be tested in Ampere’s Battery Cell Innovation Lab recently inaugurated in Lardy, France, and designed to anticipate technological breakthroughs and strengthen Renault Group’s competitiveness in the electric vehicle sector.
LXMOTM -based batteries present a highly attractive potential solution for EVs because they can deliver high energy densities comparable to or better than those using NMC (Nickel, Manganese, Cobalt) but with low cost and abuse tolerance similar to those using LFP (Lithium, Iron, Phosphate). At the systems level, the combination of improved abuse tolerance with high energy density results in pack-level energy densities that are up to twice that of either NMC- or LFP-based battery packs. This results in significant design and economic advantages to Ampere, with the promise of lower cost vehicles with longer range and better safety.
Cobalt-free technology is the third step of Ampere’s battery strategy, after NMC for its high density, and LFP which will enter Renault’s cars in 2026.
