QuantumScape Surges to 71st in Trading Volume with $10.34 Billion Day

On June 25, 2025, QuantumScape (QS) experienced a significant surge in trading volume, reaching $10.34 billion, marking an 807.83% increase from the previous day. This surge placed QuantumScape at the 71st position in terms of trading volume for the day. The stock price of QuantumScape rose by 30.95%, marking the second consecutive day of gains, with a total increase of 33.73% over the past two days.

QuantumScape's stock price surged following a major breakthrough in its battery production technology. The company announced that its Cobra ceramic separator process has become the standard in its battery production, marking a significant milestone in the development of next-generation batteries. This advancement is expected to have wide-ranging applications, not only for electric vehicles but also for general energy storage solutions.

The Cobra process represents a substantial improvement in production efficiency, treating battery cell components 25 times faster than previous methods and requiring much less equipment. This enhancement allows QuantumScape to scale production more easily, even to gigafactory levels. The new process is anticipated to deliver longer battery life, faster charging times, and lower costs, all of which are essential for the commercialization of solid-state batteries.

QuantumScape's long-time backer, Volkswagen, which holds a 24% stake in the company, is particularly interested in utilizing the new technology in its electric vehicles. Volkswagen signed a deal last year to license QuantumScape’s production technology. Additionally, QuantumScape has secured agreements to supply battery samples to several other major and luxury car manufacturers, further solidifying its position in the market.
