QuantumScape, Murata enter into ceramic separator development agreement

Murata Manufacturing (MRAAY) and QuantumScape (QS) have entered into a joint development agreement aimed at high-volume production of ceramic separators for QuantumScape’s solid-state batteries. Since February 2025, the two companies have been exploring a potential collaboration toward the high-volume production of ceramic films. Through these discussions, it was confirmed that Murata’s technologies in ceramics material formulation, sheet forming, and firing could be applied to the high-volume production of QuantumScape’s ceramic separators. As a result, the two companies have now entered into the next phase of their collaboration, which includes scaling ceramic separator production and exploring a business model for commercialization. Siva Sivaram, CEO of QuantumScape, stated: “We are pleased to continue our collaboration with Murata, a world-class ceramics manufacturer, as we work together to advance the high-volume production of our ceramic separators. Partnership with Murata is an important part of building a robust global ecosystem of suppliers to support the commercialization of QuantumScape’s solid-state battery technology.”
