QuantumScape said on Monday it has signed a partnership with Corning to develop manufacturing capabilities for ceramic separators, a key component in its next-generation lithium-metal cells.
The collaboration marks another step in QuantumScape’s effort to industrialize and scale solid-state technology, which is seen as a potential leap forward in energy storage due to higher energy density and improved safety compared with today’s lithium-ion batteries.
“Corning’s world-class capabilities in ceramics manufacturing makes it an ideal addition to the QS technology ecosystem,” said QuantumScape Chief Executive Siva Sivaram. “Together with our ecosystem partners, we’re building the foundation for scalable production of our high-performance solid-state batteries and furthering our mission to revolutionize energy storage.”
QuantumScape ended the second quarter of 2025 with enough liquidity to fund development through 2029. In June, it integrated its proprietary Cobra solid-state separator process into baseline production, paving the way for higher-volume B1 sample production of its QSE-5 cells.

Volkswagen Group’s battery subsidiary PowerCo has invested nearly $300 million into QuantumScape, which has also focused on installing higher-volume production equipment this year. The company said it plans to ship additional prototype samples to partners and outline a timeline for field testing.
Corning, known for its glass and ceramics used by companies including Apple and Samsung, is expected to help QuantumScape move closer to high-volume manufacturing of solid-state cells.
