AMPERE AND BASQUEVOLT SIGN JOINT DEVELOPMENT AGREEMENT TO ACCELERATE LITHIUM METAL-BASED BATTERY TECHNOLOGY FOR NEXT-GENERATION ELECTRIC VEHICLES

• Ampere partners with Basquevolt in a Joint Development Agreement (JDA) to fast-track lithium metal-based battery technology for Pre-A Sample EV requirements.   
• Objective: to meet the requirements of Pre-A Sample prototypes for electric vehicles.   
• Lithium metal-based battery represents a major technological leap in terms of energy density, compared to current lithium-ion batteries with liquid electrolyte

Ampere, the EV and software pure player from Renault Group, has entered into a Joint Development Agreement with Basquevolt, to accelerate the development and validation of Lithium metal-based batteries for future electric vehicles. 

Basquevolt’s lithium metal-based battery technology offers a transformative leap in energy density compared to today’s liquid-electrolyte lithium-ion batteries. By combining the advantages of polymer electrolyte with advanced anode, the technology has the potential to enable compact, lightweight battery packs with superior thermal stability and fast-charging capabilities, key attributes for the next generation of electric mobility.  

This collaboration underscores the importance of strategic partnerships in driving battery innovation, combining cutting-edge science with scalable engineering and cost efficiency. Together, Ampere and Basquevolt aim to pave the way for the commercial deployment of lithium metal-based battery technology in electric vehicles.  

“Entering this next phase with Ampere marks a major milestone in our mission to bring polymer electrolyte technology closer to the mass market,” explains Pablo Fernández, CEO of Basquevolt.  

“Together, we are focused on validating performance in real-world automotive conditions and accelerating the transition to next-gen EV batteries that meet the evolving needs of our customers,” adds Nicolas Racquet, VP Vehicle & Powertrain Engineering, Ampere.  

After more than twelve months of collaboration, Basquevolt is already demonstrating that its technology can achieve very high energy density while significantly reducing the overall battery pack costs. Thanks to its polymer electrolyte, battery cells can be produced through a simpler and more efficient manufacturing process. This competitive advantage will result in approximately 30% lower capital investment per GWh in a conventional gigafactory and 30% less energy used per kWh produced.
