Is this U.S.-China selloff a buy? A top Wall Street voice weighs in
Investing.com -- QuantumScape (NYSE:QS) stock rose 7% Wednesday after the solid-state battery developer announced a joint development agreement with Murata Manufacturing for the production of ceramic separators used in its batteries.
The partnership aims to scale up the high-volume production of ceramic separators, which are critical components in QuantumScape’s solid-state battery technology. The agreement follows exploratory discussions that began in February 2025, during which the companies determined that Murata’s expertise in ceramics material formulation, sheet forming, and firing could be applied to mass-producing QuantumScape’s ceramic separators.
"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," said Dr. Siva Sivaram, CEO of QuantumScape. "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."
Murata’s President Norio Nakajima expressed similar enthusiasm, noting that the company will "leverage its strengths in ceramics technology to contribute to the high volume production of QuantumScape’s solid state batteries."
The agreement represents a significant step forward in QuantumScape’s commercialization efforts, as the companies will now focus on scaling ceramic separator production and exploring business models for bringing the technology to market.
