QuantumScape shares increase by 30% after hours.

QuantumScape Inc. (QS) saw a significant increase in its stock price after hours on June 19, 2025, with shares rising by 30%. The upward movement was largely driven by the company's recent milestones and strategic partnerships in the solid-state battery sector.

QuantumScape has been making steady progress in its solid-state battery technology, which promises to revolutionize the electric vehicle (EV) industry. The company's latest achievements include the development of its "Cobra" separator production process [1], which is ready for initial separator processing, and the beginning of low-volume production of its initial B-sample cells for OEM testing [2]. Additionally, QuantumScape has signed an agreement with Volkswagen Group's PowerCo to mass produce its solid-state battery technology [3].

These developments have bolstered investor confidence in QuantumScape's ability to commercialize its technology and compete in the rapidly growing EV market. The company's solid-state batteries have shown promising results, including the potential for EVs to drive 500,000 kilometers without range loss [4], and the ability to fast charge in 15 minutes through 400 consecutive cycles [5].

The surge in QuantumScape's stock price reflects the market's optimism about the company's technological advancements and strategic partnerships. However, investors should remain cautious and continue to monitor the company's progress and financial performance.
