Ampere, the electric vehicle (EV) and software-focused entity of Renault Group, has entered into a joint development agreement with Basquevolt to accelerate development and validation of lithium metal-based batteries for future EV platforms.
The collaboration is focused on fast-tracking the technology toward Pre-A sample requirements for EV prototype integration. Basquevolt’s approach combines a polymer electrolyte with an advanced anode architecture, targeting higher energy density than conventional liquid-electrolyte lithium-ion systems.
The chemistry is intended to support more compact battery pack configurations, improved thermal stability, and fast-charging performance.
Lithium metal systems have long been viewed as a pathway to increasing gravimetric and volumetric energy density. The joint effort centers on validating performance under automotive operating conditions and assessing scalability for production.
After more than 12 months of collaboration, Basquevolt reports progress toward high energy density targets while pursuing reductions in overall pack cost. The polymer electrolyte architecture is also designed to simplify manufacturing relative to current liquid-electrolyte processes. The companies indicate the approach could reduce capital investment requirements per GWh by approximately 30% in conventional gigafactory settings, while lowering energy consumption per kWh produced by a similar margin.
The agreement reflects ongoing efforts within the EV sector to evaluate advanced chemistries that balance energy density, cost structure, manufacturability, and integration readiness.
