BASQUEVOLT launches 402 Wh/kg Li-metal NMC cell with 8.9C pulse power, manufactured in Spain

BASQUEVOLT has introduced the BQV400L, its inaugural standardised commercial battery cell, marking a significant development in European battery manufacturing. The cell features a lithium metal anode paired with an NMC cathode and utilises BASQUEVOLT’s proprietary polymer electrolyte. Manufactured in Spain with 75% of components sourced from Europe, the 27 Ah cell delivers an impressive energy density of 402 Wh/kg and supports an 8.9C pulse power output, making it suitable for high-performance electric vehicle applications. The lithium metal chemistry represents a transitional technology towards full solid-state batteries, offering higher theoretical energy density compared to traditional graphite anodes. BASQUEVOLT’s polymer electrolyte aims to address the typical challenges associated with lithium metal, such as safety and cycle life, while the industry progresses towards solid-state solutions. Importantly, the BQV400L is designed to be compatible with existing gigafactory production lines, allowing manufacturers to adopt the new cell without substantial additional capital expenditure. BASQUEVOLT is pursuing rigorous safety certification, with an HL3 rating currently undergoing independent verification. The company has also entered a Joint Development Agreement with Ampere, the electric vehicle division of Renault Group, to validate the cell under automotive conditions. Additionally, EDF has tested the battery’s safety and performance in collaboration with an unnamed original equipment manufacturer, signalling growing industry interest in the technology. Nicolò Campagnol, BASQUEVOLT’s Chief Program Officer, highlighted the milestone of achieving over 400 Wh/kg in a commercially available European-made cell, emphasising the promising technological roadmap ahead. The launch of the BQV400L reflects BASQUEVOLT’s commitment to advancing lithium metal battery technology within Europe and supporting the continent’s ambitions for energy storage and electric mobility. The cell is now available for commercial use, positioning BASQUEVOLT as a notable player in the competitive battery market.
