QuantumScape Corporation, a leading innovator in solid-state lithium-metal battery technology, has officially inaugurated its Eagle Line a highly automated pilot production facility at its headquarters in San Jose. The event, held in February 2026, was attended by automotive customers, strategic partners and government officials, marking a key step in the company’s drive to advance next-generation battery manufacturing.
The Eagle Line represents a major milestone in QuantumScape’s long-term strategy to scale production of its QSE-5 solid-state cells. Built with cutting-edge automation and processes, this pilot line is designed to demonstrate scalable manufacturing methods and form the foundation for future gigawatt-hour-level production by licensing partners.
Central to the Eagle Line’s capabilities is QuantumScape’s proprietary Cobra separator process, which produces ceramic separators critical to solid-state battery performance. This process, now integrated into the company’s production workflow, enhances throughput and quality — enabling the Eagle Line to support higher-volume cell assembly and testing.
Once fully ramped up, the Eagle Line is expected to supply battery cells for customer sampling, testing and technology demonstrations, while also serving as a platform for further process improvements. The facility’s output will help automotive and energy partners evaluate QuantumScape’s technology ahead of full-scale commercial deployment.
QuantumScape executives described the Eagle Line as a pivotal achievement in the firm’s commercialization journey. According to CEO Dr. Siva Sivaram, the new line illustrates the company’s progress in translating laboratory breakthroughs into industrial-ready production systems — a critical advance toward broader adoption of solid-state batteries.
The inauguration follows a strong year of progress for QuantumScape, which in late 2025 completed the installation of key production equipment for the Eagle Line and began shipping advanced B1 QSE-5 cell samples featuring the Cobra process. These efforts underscore the company’s commitment to delivering higher-performance, safer and faster-charging battery technologies to the automotive and energy markets.
