When JB Straubel, the co-founder of Tesla and founder of Redwood Materials, joined QuantumScape’s Strategic Advisory Board in June, it wasn’t just another executive appointment—it was a signal that the long-promised era of solid-state EV batteries may finally be nearing reality. Based in San Jose, California, QuantumScape has spent over a decade refining a next-generation battery technology that could redefine electric mobility: solid-state lithium-metal cells with no liquid electrolyte, meaning higher energy density, faster charging, and a far lower risk of fire. After years of lab-scale progress, the company is now accelerating toward commercial production, backed by powerful alliances and breakthroughs in manufacturing.
For years, the promise of solid-state batteries has hovered just out of reach—promising twice the range of conventional EVs and charging in minutes, not hours, but stalling at the production stage. QuantumScape’s recent moves suggest that barrier is cracking. In June 2024, the company announced a multi-year R&D partnership with Honda, following the automaker’s successful technical evaluation of QuantumScape’s battery platform. This isn’t theoretical: Honda conducted hands-on testing and competitive benchmarking, a strong endorsement of the technology’s readiness. The collaboration will focus not only on refining the battery itself but also on scaling up manufacturing—a critical hurdle for any new energy technology.
Equally significant is QuantumScape’s partnership with Corning, the New York-based materials science giant, announced in September 2023. Corning is applying its Ribbon Ceramics manufacturing process—a roll-to-roll technique capable of producing ultra-thin, durable ceramic separators—to support mass production of solid-state batteries. This innovation could dramatically reduce costs and increase throughput, addressing one of the biggest bottlenecks in bringing the technology to market. Meanwhile, QuantumScape’s proprietary method of self-forming anodes during the first charge eliminates a complex and expensive fabrication step, streamlining production further.
The addition of both Straubel and Dr. Mark Maybury—a former US Air Force Chief Scientist and Lockheed Martin executive—to the Strategic Advisory Board underscores the company’s pivot from research to real-world deployment. With deep expertise in scaling battery manufacturing and transitioning advanced tech into commercial products, their guidance could prove pivotal. Backed by long-term support from Volkswagen’s PowerCo and now Honda, QuantumScape is positioning its batteries not just for cars, but for AI data centers and aerospace applications.
While a consumer-ready QuantumScape battery isn’t on shelves yet, the momentum is undeniable. Every new partnership, every technical validation, brings the electric future one step closer—not from distant policy mandates, but from the quiet, relentless work of engineers and innovators in California labs. The revolution isn’t coming. It’s already here, charging up in silence.
