- The rally stems from delayed reaction to late-June announcement of successful Cobra separator process integration
- New Cobra process delivers 25-fold improvement in heat treatment speed compared to previous Raptor process

QuantumScape shares surged 16.69% to $8.18 on Tuesday in a session marked by exceptionally heavy trading volume. The solid-state battery developer saw 72.36 million shares change hands, more than three and a half times its 100-day average volume of 20.386 million shares.
The stock’s upward momentum appears to be a delayed reaction to the company’s late-June announcement about its manufacturing breakthrough. Investors are continuing to rally behind QuantumScape’s successful integration of its advanced Cobra separator process into baseline cell production.
This manufacturing milestone represents a critical step for the company as it progresses toward large-scale commercialization of its battery technology. The Cobra process enables faster and more energy-efficient production of the company’s proprietary ceramic separators, a core component of its lithium-metal batteries.
According to QuantumScape, the new process boasts a 25-fold improvement in the speed of heat treatment compared to the prior-generation “Raptor” process. This leap in manufacturing efficiency is being viewed by investors as a crucial step toward establishing a scalable gigafactory production line.
Proudly announcing a big technical milestone for the year: we've successfully integrated our Cobra separator process into baseline production operations. Cobra has a ~25x improvement in speed & occupies a fraction of the physical space of Raptor. https://t.co/lDa5LFHQbE
