QuantumScape Corporation on October 21, 2026 announced plans for a 100 megawatt-hour (MWh) capacity cell production line intended to meet demand for solid-state batteries from markets including AI data centers, aerospace and defense, with the start of cell production on the planned line targeted for 2028.

To develop the line, the San Jose, California-based company has partnered with Muehlbauer Group, a German automation and manufacturing technology company, as an ecosystem provider of cell assembly equipment, according to the company’s announcement. QuantumScape describes itself as a global leader in solid-state lithium-metal battery technology and says its technology is designed to enable greater energy density, faster charging and enhanced safety.

QuantumScape 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, and engineering work on higher-throughput processes and equipment for the new line is underway, the company said.

Dr. Siva Sivaram, president and CEO of QuantumScape (QS ), said the company is excited to welcome Muehlbauer to the QS ecosystem, describing the German firm as an experienced and respected global player in manufacturing automation and battery equipment with “top-tier system integration capability, impressive engineering depth, and the scalability mindset necessary to bring our groundbreaking technology to the gigawatt-hour scale.” Sivaram said Muehlbauer joins what he called a world-class ecosystem of technology partners as the company works to 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. He said his company has been working on-site with QuantumScape in San Jose to develop a scale-up plan built on the foundation of the Eagle Line. Mühlbauer described his company as a preferred partner within QuantumScape’s ecosystem, citing decades of experience in turning innovative technologies into scalable production processes.

Eagle Line Pilot Facility

QuantumScape inaugurated the Eagle Line at its San Jose facility on February 4, 2026, at an event attended by automotive OEM customers, QS ecosystem partners and government officials, according to the inauguration announcement. The event included a showcase tour of the line, and Sivaram said the company was showing the Eagle Line to the world for the first time.

QuantumScape describes the Eagle Line as a suite of equipment, materials and highly automated processes forming the blueprint for production of QS technology. The line incorporates the company’s Cobra process, which QuantumScape calls a unique and highly scalable method for producing its proprietary separator. The company said that upon ramp-up, the Eagle Line will produce QS battery cells to support customer sampling and testing, technology demonstrations and product integration efforts. It is also intended to demonstrate scalable production of QS technology so that licensing partners can manufacture at gigawatt-hour scale in their own facilities, and to serve as a platform to develop and test further technology and process improvements at meaningful scale.

Dr. Luca Fasoli, QuantumScape’s chief operating officer, said in the February announcement that after deploying the Cobra process, the team rapidly moved to scale up the cell build process to increase output, scalability, automation and quality. Sivaram said the line marked the next major step in the commercialization of the company’s technology.

Muehlbauer Group Profile

The October announcement describes Muehlbauer Group as one of the most advanced suppliers of complete production solutions, with around 4,500 employees at 40 locations worldwide and 45 years of experience. It states that the group has achieved a leading position in the semiconductor industry with its die sorting technology and serves 90% of worldwide demand for RFID, and that more than 90,000 Muehlbauer machines and systems have been installed worldwide. The group specializes in high-precision, high-speed assembly systems, including in cleanroom environments.

QuantumScape stated that its expectations for the Muehlbauer partnership and for the design, development, build-out and timing of the planned 100 MWh cell production line, including the engineering of higher-throughput processes and equipment and the targeted 2028 start of production, are forward-looking statements subject to risks and uncertainties. Among the factors the company cited are the successful development and commercialization of its solid-state battery technology, the performance of third-party partners and suppliers, and market demand for EVs, AI data center, aerospace and defense, and other energy storage applications.
