QuantumScape, the solid-state battery developer backed by Volkswagen, has entered into a strategic agreement with Murata Manufacturing to explore collaboration on large-scale production of ceramic separators for its next-generation battery cells.
Japanese tech group Murata Manufacturing is globally recognised for its leadership in the development and production of passive electronic components and ceramic-based solutions, as well as communications and power supply modules.
QuantumScape is currently building out a robust ecosystem of strategic partners to industrialise its solid-state battery technology – an ecosystem that includes equipment suppliers, materials partners, automotive OEMs and contract manufacturers. Murata is now the latest addition to this growing network.
“Murata’s deep expertise in high-precision ceramics manufacturing makes them an exceptional partner as we look to scale production of our proprietary ceramic separator,” said QuantumScape CEO Siva Sivaram.
“By combining our groundbreaking Cobra separator production process with Murata’s proven capabilities and global manufacturing strength, this agreement has the potential to create significant value,” Sivaram continued. “It brings together QS’s advanced solid-state battery technology with Murata’s longstanding track record of delivering ceramic-based electronic components for some of the world’s most demanding applications.”
QuantumScape is based in San José, California. It is looking to develop solid-state lithium-metal batteries for electric vehicles. Its proprietary technology is centred around a solid ceramic separator, which enables the use of lithium-metal anodes – a configuration that promises significantly higher energy density, faster charging, and enhanced safety over conventional lithium-ion cells.
Volkswagen has been a key backer of QuantumScape since 2012 and remains its largest shareholder. In July 2024, the company signed a landmark licensing agreement with Volkswagen’s battery subsidiary PowerCo. Under this deal, PowerCo secured the rights to mass-produce battery cells based on QuantumScape’s technology, with an initial annual production capacity of up to 40 GWh, expandable to 80 GWh.
