QuantumScape, a developer of solid-state lithium-metal batteries, said on Thursday it has started shipping B1 samples of its QSE-5 cell, marking a key milestone in the third quarter of 2025.
The QSE-5 cells feature separators produced using the company’s Cobra process. QuantumScape said the combination of the new cell design and improved production processes represents a step toward higher-volume manufacturing of its battery technology for electric vehicles and other applications.

The Cobra-based QSE-5 cells are included in the company’s first vehicle program with the VW Group, which features the Ducati V21L motorcycle. The program is intended to test the performance of the solid-state battery technology in real-world conditions.
QuantumScape is also installing an automated cell production pilot line, the Eagle Line, at its San Jose, California headquarters to support further scaling of production.
