Electric mobility firm Ampere has signed a joint development agreement with Spanish battery technology company Basquevolt to accelerate the development of lithium metal-based batteries for future electric vehicles.
The collaboration will focus on advancing and validating a new generation of battery technology designed to improve energy density, charging performance and overall efficiency in electric cars. The project will be carried out in Spain and forms part of wider efforts to support innovation within Europe’s rapidly evolving electric mobility sector.
Basquevolt’s lithium metal-based batteries are based on polymer electrolyte technology, which differs from the liquid electrolyte systems used in most current lithium-ion batteries. According to the company, this design could significantly increase the amount of energy stored in each battery while also enabling lighter and more compact battery packs.
Industry specialists say such improvements are essential for the next generation of electric vehicles, where manufacturers are seeking longer driving ranges, faster charging times and improved thermal safety.
By combining Basquevolt’s advanced battery research with Ampere’s engineering and vehicle integration expertise, the two companies aim to accelerate the path towards commercial deployment of the technology in passenger vehicles.
Pablo Fernández, Chief Executive Officer of Basquevolt, said the agreement represents an important step in bringing polymer electrolyte battery technology closer to large-scale production. He noted that working with Ampere will help validate the performance of the batteries under real-world automotive conditions.
Nicolas Racquet, Vice President for Vehicle and Powertrain Engineering at Ampere, added that the partnership highlights the growing role of collaboration in the development of next-generation energy storage systems.
“Together we aim to accelerate the development of advanced EV batteries capable of meeting the evolving expectations of customers,” Racquet said.
The two companies have already worked together for more than a year to refine the technology. Early tests indicate that the batteries could achieve high energy density while also reducing the cost of battery packs compared with traditional lithium-ion solutions.
Basquevolt says its polymer electrolyte approach simplifies the battery cell manufacturing process, potentially lowering production costs and energy consumption at gigafactories. The company estimates that facilities producing the cells could require around 30% less capital investment per gigawatt-hour of capacity, while energy use per kilowatt-hour of battery output could fall by a similar margin.
If successfully commercialised, the technology could help manufacturers produce more efficient and affordable electric vehicles, supporting the broader transition to low-emission transport across global markets.
