QuantumScape has initiated shipments of B1 samples of its QSE-5 cell, marking the achievement of a key 2025 objective during the third quarter. These cells, the most technically advanced produced by the company to date, integrate separators manufactured via the Cobra process. By unifying the high-performance QSE-5 architecture with optimized manufacturing methods, QuantumScape is accelerating progress toward high-volume commercial production for electric vehicles and stationary energy storage.
The Cobra-enabled QSE-5 cells are currently deployed in the company’s first vehicle demonstration program with the Volkswagen Group, in the form of Ducati V21L motorcycles. This application provides a real-world platform to validate the solid-state batteries’ no-compromise performance profile, including rapid charging capabilities, enhanced safety, and higher energy density compared to conventional lithium-ion cells.
To support the transition from sample shipments to mass production, QuantumScape is installing a highly automated pilot line, known as the Eagle Line, at its San Jose, California headquarters. This facility will enable the company to refine cell assembly processes, improve yield consistency, and demonstrate automotive-grade reliability ahead of full-scale manufacturing.
“We are proud to announce the start of deliveries of these QSE-5 samples,” said Dr. Luca Fasoli, Chief Operating Officer of QS. “We are working together with our partners to bring our groundbreaking solid-state lithium-metal battery technology to market as quickly as possible. This announcement is another critical step toward achieving our goal of revolutionizing energy storage.”
QuantumScape’s solid-state design is engineered to support faster charging rates, greater energy density, and improved safety characteristics—attributes that are essential for next-generation electric vehicles and sustainable energy infrastructure. By achieving this sample shipment milestone and deploying the Eagle Line, the company continues to execute on its roadmap for scaling solid-state battery technology.
