QuantumScape up 29% after announcing Cobra separator process milestone

QuantumScape (QS) shares are up 29% afterhours at $5.57. Earlier, the company stated: “QuantumScape announced a major milestone in the scale-up of its production capabilities: the successful integration of its advanced Cobra separator process into baseline cell production. Cobra forms the foundation of QS’s high-throughput, continuous-flow separator production platform. Designed to enable faster, more energy-efficient production with a smaller equipment footprint compared to earlier processes, Cobra represents a step-change improvement in ceramic separator manufacturing. Compared to the prior-generation Raptor process, Cobra offers a ~25x improvement in heat treatment speed and occupies a fraction of the physical space per film start – key advantages in the design of a scalable gigafactory production line.”
