QuantumScape Partners with Murata to Accelerate Solid-State Battery Production

QuantumScape (QS) has forged a strategic partnership with Murata Manufacturing (MRAAF), a Japanese electronics leader, to scale production of ceramic separators for solid-state batteries. The joint development agreement aims to enhance safety, charging speed, and energy density—critical metrics for next-generation energy storage.

The collaboration follows QuantumScape's recent deal with Corning (GLW), signaling rapid progress toward commercialization. Murata's expertise in ceramic materials positions the partnership to bridge the gap between lab-scale tests and industrial production. Discussions began in February 2025, reflecting deliberate planning for manufacturing scale-up.

Investors have responded positively, driving QS stock up 195% year-to-date in 2025. The company's QSE-5 battery prototypes have undergone real-world testing, though challenges remain in achieving mass-market viability. These developments coincide with growing global demand for advanced battery technologies across electric vehicles and grid storage applications.
