QuantumScape Announces Plans for 100 MWh Solid-State Battery Production Line for AI Data Centers, Aerospace and Defense

Partners with Muehlbauer Group for Production Equipment

SAN JOSE, Calif., Oct. 21, 2026 (GLOBE NEWSWIRE) -- QuantumScape Corporation (NASDAQ: QS), a global leader in solid-state lithium-metal battery technology, today announced a planned 100 megawatt-hour (MWh) capacity cell production line to meet demand for solid-state batteries from markets including AI data centers, aerospace and defense. To develop this line, QS has partnered with Muehlbauer Group, a leading German automation and manufacturing technology company, as an ecosystem provider of cell assembly equipment.

QS is currently demonstrating scalable production of solid-state batteries using its highly automated Eagle Line pilot facility in San Jose. Muehlbauer evaluated the Eagle Line processes and developed design enhancements to bring the technology to mass production; engineering work on higher-throughput processes and equipment for the new line is underway. Start of cell production is targeted for 2028.

“We are excited to welcome Muehlbauer to the QS ecosystem,” said Dr. Siva Sivaram, president and CEO of QS. “Muehlbauer is an experienced and respected global player in manufacturing automation and battery equipment, and they’ve shown top-tier system integration capability, impressive engineering depth, and the scalability mindset necessary to bring our groundbreaking technology to the gigawatt-hour scale. They join a world-class ecosystem of technology partners as we bring solid-state batteries into mass production.”

“The Eagle Line proved to us that QuantumScape’s solid-state technology is ready to scale to the next level,” said Josef Markus Mühlbauer, CEO of Muehlbauer Group. “We have been working on-site with QS in San Jose to develop a scale-up plan built on the foundation of the Eagle Line. With decades of experience in turning innovative technologies into scalable production processes, we are proud to be a preferred partner within QuantumScape’s ecosystem and to contribute our expertise to the mission of revolutionizing energy storage and enabling a more sustainable future.”
