Solid-state battery developer QuantumScape has announced a partnership with Corning Incorporated, one of the world’s leaders in glass, ceramics, and materials science, to develop new manufacturing capabilities. This agreement is another foundational step in QuantumScape’s quest to build a network of partners that will enable it to finally industrialize and scale its next-generation solid-state battery technology.
Anytime we hear anything from the QuantumScape ($QS) newsroom, it’s almost always something encouraging and/or exciting (albeit complicated and jargon-heavy). That’s to be expected when you’re one of the world leaders in developing next-generation solid-state battery technology – expected to one day arrive as the next evolution in battery tech and deliver a paradigm shift in energy density and safety.
Last we heard, QuantumScape had ended Q2 2025 with enough financial runway to continue solid-state battery development through 2029. Last June, QS’s proprietary Cobra solid-state separator process was fully integrated into its baseline production processes, enabling gigawatt-level solid-state cell production.
The Cobra breakthrough has laid the groundwork for higher-volume B1 sample production of its flagship QSE-5 solid-state lithium-metal cells, which will eventually lead to scaled output for the battery market, especially in the form of BEV batteries.
QuantumScape has secured significant financial backing through its partner, PowerCo – the battery division of the Volkswagen Group, which has committed an investment of nearly $300 million. As QuantumScape’s production practices continue to evolve, it has secured a new partner in Corning Incorporated to develop and commercialize ceramic separator (a key component in solid-state battery tech) manufacturing.
QuantumScape partners with Ceramic specialist Corning
QuantumScape shared details this morning as it announced Corning as its latest development partner. Corning Inc. ($GLW) is a leader in glass and ceramics, providing materials to tech giants like Apple and Samsung. Through the agreement, QS and Corning intend to jointly develop ceramic separator manufacturing capabilities for the former’s solid-state batteries.
The ultimate goal of the partners is to achieve high-volume production of QuantumScape’s ceramic separators to expedite the commercialization of its solid-state technology. QS CEO and President, Dr. Siva Sivaram, elaborated:
Corning’s world-class capabilities in ceramics manufacturing makes it an ideal addition to the QS technology ecosystem. 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.
Today’s news is another example of QuantumScape securing viable partners with renowned experience in materials science and manufacturing to create its own system of next-generation battery manufacturing at scale.
As pointed out in its Q2 2025 report, QuantumScape is focused on installing higher-volume cell production equipment this year to support the scaled production of its solid-state cells. From there, QS will look to ship more samples of its prototype cells to its partners and share a more concrete timeline for actual field testing
