Overview
- Ampere, Renault Group’s EV and software unit, and Basquevolt agreed to co-develop and validate lithium‑metal solid‑state battery cells for future vehicles.
- The pact focuses on assessing integration into Renault EVs rather than establishing a mass-production supply contract at this stage.
- Basquevolt’s polymer‑electrolyte design with a lithium‑metal anode is presented by the companies as enabling higher energy density, improved thermal stability, and faster charging in lighter packs.
- The partners say the manufacturing process could be simpler, with about 30% lower capital investment per GWh and roughly 30% less energy used per kWh in prospective gigafactories.
- The agreement follows months of prior collaboration, with Basquevolt advancing the work from its Vitoria‑Gasteiz facilities while also engaging other major European automakers.
