QuantumScape said it has officially launched its Eagle Line production facility in San Jose, California, marking a key step toward commercial-scale manufacturing of its solid-state lithium-metal batteries for electric vehicles.
The facility, inaugurated on Feb. 4, was unveiled during an event attended by automotive original equipment manufacturers, technology partners, government representatives and media. QuantumScape said the Eagle Line is designed as a full manufacturing blueprint, integrating proprietary equipment, materials and automated processes tailored to its solid-state battery technology.

At the core of the line is QuantumScape’s Cobra process, a scalable manufacturing method developed to produce the company’s solid-state battery separators. The company said the Eagle Line will be used to supply battery cells for customer sampling and validation testing, support technology demonstrations and integration work, and showcase production capabilities to potential licensing partners targeting gigawatt-hour-scale manufacturing.
Solid-state batteries are widely viewed as a potential breakthrough for electric vehicles, promising higher energy density, faster charging and improved safety by eliminating flammable liquid electrolytes. Automakers globally are investing heavily in next-generation battery technologies as they seek to extend driving range and accelerate EV adoption.

“This is our Kitty Hawk moment, our Apollo mission launch,” said Siva Sivaram, president and chief executive of QuantumScape, at the launch event. “The Eagle Line is a powerful platform to demonstrate scalable production of our solid-state technology and serve customer demand for better batteries.”
QuantumScape said the Eagle Line also serves as a development platform, allowing the company to refine process controls, automation and quality at a scale closer to commercial production. According to Sivaram, the facility moved from planning to a completed production line in about ten months.
Chief operating officer Luca Fasoli said the deployment of the Cobra process enabled rapid scale-up of cell production. “We rapidly moved to increase output, scalability, automation and quality,” he said, calling the Eagle Line a major technical achievement for the company.

Chief technology officer Tim Holme said the facility highlights the challenges of transitioning solid-state battery technology from laboratory development to manufacturing environments, noting that the Eagle Line’s automated systems are designed to meet automotive-grade requirements.
QuantumScape said the line underpins its strategy to license the technology to partners, enabling large-scale deployment without the company building all manufacturing capacity itself. The approach could help accelerate adoption of solid-state batteries as automakers look to secure long-term supplies of next-generation energy storage.
