On 2 October 2025, QuantumScape Corporation and Corning Incorporated announced a joint agreement to develop high‑volume ceramic separator manufacturing for QuantumScape’s solid‑state lithium‑metal batteries. The partnership will focus on scaling the production of the ceramic separators that are integral to the QSE‑5 cell, QuantumScape’s first planned commercial battery.
Ceramic separators are a key differentiator for QuantumScape’s technology, providing superior safety, higher energy density, and faster charging compared to conventional polymer separators. By leveraging Corning’s world‑class ceramics manufacturing expertise, the collaboration aims to reduce production costs and accelerate the transition from laboratory prototypes to commercial‑grade cells.
The agreement complements QuantumScape’s existing licensing partnership with Volkswagen Group’s PowerCo, positioning the company to meet its 2026 field‑testing target and to secure a scalable supply chain for its next‑generation batteries.
