Renault Partners with Basquevolt to Develop Solid-State Bat

On February 24, 2026, Renault announced a strategic partnership with Basquevolt, a Spanish company specializing in solid-state battery technology, based in Bilbao. The collaboration aims to develop lithium-metal batteries that integrate a solid electrolyte and a self-forming anode, which are expected to yield lighter, more compact battery packs with significantly higher energy density compared to current liquid electrolyte lithium-ion batteries. This project aligns with Renault's Ampere roadmap towards real-world automotive conditions and industrial preparation for 2030.

This collaboration represents a critical step in advancing European electric vehicle technology amidst global competition, particularly from Chinese manufacturers. By enhancing battery energy density and reducing weight, Renault aims to improve electric vehicle performance and autonomy. The partnership could strengthen Europe's position in the battery technology landscape, potentially reducing its reliance on foreign suppliers and contributing to regional tech sovereignty.
