On October 23, 2025, QuantumScape announced that it has begun shipping B1 samples of its QSE‑5 solid‑state lithium‑metal battery cell. The shipment marks the first commercial‑grade delivery of the QSE‑5 platform and fulfills a key annual objective set for 2025. The B1 cells incorporate separators produced with the company’s Cobra process, which has been demonstrated to increase separator throughput by more than 25‑fold compared with earlier methods.
The B1 samples are destined for the company’s first vehicle program with the Volkswagen Group, specifically the Ducati V21L motorcycle, which serves as a real‑world demonstration of the QSE‑5’s no‑compromise performance profile. By shipping these cells, QuantumScape moves closer to achieving automotive‑grade reliability and high‑volume production, a critical step for the company’s commercialization roadmap. The launch of the Eagle Line, a highly automated cell‑production pilot line at the San Jose headquarters, supports the scaling of the Cobra‑based process.
This milestone underscores QuantumScape’s progress in translating laboratory breakthroughs into production‑ready technology. The company’s focus on a capital‑light licensing model means that the B1 shipments also signal to partners that the technology is ready for joint scale‑up, potentially accelerating the path to revenue generation. The event represents a tangible advance in the company’s journey toward commercial deployment of solid‑state batteries.
