Ampere, a division of Renault Group, has formed a joint development agreement (JDA) with Stratus Materials Inc. to investigate the application of LXMO (Lithium X Manganese Oxide) battery technology, a cobalt-free option, for Renault's future electric vehicles. The LXMO technology promises high-energy density akin to nickel manganese cobalt (NMC) batteries while maintaining cost efficiency and abuse tolerance similar to lithium iron phosphate (LFP) batteries. This research is part of Ampere's strategy to develop next-generation battery technologies succeeding NMC and LFP cells.

The collaboration aims to assess the suitability of integrating Stratus Materials' high-energy cobalt-free LXMO into Renault's EV lineup, focusing on delivering high performance in EV-format battery cells. Testing will occur at Ampere's Battery Cell Innovation Lab in Lardy, France, which aims to foresee technological breakthroughs and bolster Renault Group's competitiveness in the EV sector.

The LXMO batteries present a promising solution for EVs, offering high-energy densities with low costs and high safety, potentially resulting in vehicles that are more cost-effective with extended range and enhanced safety features. This technology marks a significant third step in Ampere's battery strategy, following NMC's high density and LFP's anticipated introduction to Renault vehicles in 2026.

Nicolas Racquet, vice president of Vehicle & Powertrain Engineering from Ampere, noted the potential of high-energy cobalt-free materials for their unique combination of performance, cost, safety and cycle life. Jay Whitacre, CEO of Stratus, expressed enthusiasm about the partnership and the selection of LXMO as a candidate for Renault's future vehicle portfolio, indicating strong progress and prospects for full vehicle deployments.

This partnership underscores Ampere's commitment to advancing EV technology with innovative solutions that enhance performance while reducing environmental impact and supply chain complexity.
