President: Norio Nakajima
Murata Manufacturing Co., Ltd. (hereinafter referred to as “Murata”) and QuantumScape Corporation (hereinafter referred to as “QuantumScape”) 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.

Business Description: Development of next-generation solid-state lithium-metal battery technology for electric vehicles.
* solid-state lithium-metal battery: A solid-state lithium-metal battery replaces the polymer separator with a solid-state separator. This design enables a lithium-metal anode to be used, which is more energy dense than conventional anodes, allowing the battery to store a greater amount of energy in the same volume.
