QuantumScape Stock Surges Post Announcing A Strategic Partnership – Check Out The Details

QuantumScape Corp. (QS) on Tuesday announced a strategic partnership with Corning Inc. (GLW) to advance the production of ceramic separators used in next-gen solid-state batteries. 

The collaboration aims to scale up manufacturing for the commercial deployment of QuantumScape's lithium-metal battery technology.

Following the announcement, QuantumScape stock traded over 5% higher in Tuesday’s premarket and became the top trending equity ticker on Stocktwits. 

However, retail sentiment around the stock shifted to ‘bearish’ from ‘neutral’ the previous day amid ‘normal’ message volume levels.

The companies plan to co-develop the processes needed for high-volume manufacturing of the ceramic components critical to QuantumScape’s battery design. The core of the partnership centers on ceramic separators, which are a key innovation in QuantumScape’s battery technology. 

Unlike conventional liquid-based lithium-ion batteries, QuantumScape’s approach utilizes solid ceramic materials to separate battery components, offering potential improvements in safety and performance.

“Together with our ecosystem partners, we’re building the foundation for scalable production of our high-performance solid-state batteries and furthering our mission to revolutionize energy storage,” said QS President and CEO, Siva Sivaram.

By combining Corning’s experience in precision glass and ceramics production with QuantumScape’s battery technology, the companies aim to bridge the gap between lab-scale prototypes and fully industrialized products. 

On September 8, QuantumScape announced the first-ever real-world test of its solid-state lithium-metal battery in a functioning electric vehicle, featuring a Ducati motorcycle equipped with QuantumScape’s QSE-5 battery cells.

QuantumScape stock has gained over 138% in 2025 and 115% in the last 12 months.
