QuantumScape Achieves Key Production Milestone with Cobra Separator Integration

QuantumScape Corporation (NYSE:QS) is one of the best performing mid cap stocks so far in 2025. On June 24, QuantumScape announced the successful integration of its advanced Cobra separator process into baseline cell production. This represents a key 2025 goal and a step towards the commercialization of its battery technology.

The Cobra process forms the core of QuantumScape’s high-throughput and continuous-flow separator production platform. Compared to the previous-generation Raptor process, Cobra offers a 25x improvement in heat treatment speed and requires a fraction of the physical space per film start, which are advantages for designing a scalable gigafactory production line.

With Cobra now as the new baseline, QuantumScape aims to lay the groundwork for higher-volume B1 sample production. The company expects that future iterations of Cobra will continue to enhance these production metrics. QuantumScape expects to begin shipping QSE-5 B1 samples, which will be used for the testing phase of its launch program in 2026. The company also has a partnership with Volkswagen’s PowerCo subsidiary, which is licensed to produce up to 80 GWh/year of QuantumScape’s cells.

QuantumScape Corporation (NYSE:QS) develops and commercializes solid-state lithium-metal batteries for electric vehicles and other applications in the US.
