QuantumScape Announces Planned 100 MWh Solid‑State Battery Line With German Automation Partner

The deal aims to apply Eagle Line lessons and automated cell‑assembly to move toward gigawatt‑hour scale manufacturing for AI data centers, aerospace and defense.

Overview

  • QuantumScape announced the planned 100 MWh cell production line and a manufacturing partnership with Germany’s Muehlbauer on Wednesday, a move that sent the company’s shares up in after‑hours trading.
  • The partnership will have Muehlbauer design and supply high‑throughput automated cell‑assembly equipment while joint engineering work is underway to scale processes for mass production.
  • QuantumScape says the plan builds on learnings from its highly automated Eagle Line pilot in San Jose, which Muehlbauer reviewed and used to propose specific design enhancements for scale‑up.
  • The company is targeting the start of cell production in 2028 but has not disclosed key details such as project financing, factory site, capital cost, production throughput, or customer offtake agreements.
  • If successful, the line would target non‑automotive, high‑performance markets that value higher energy density, faster charging and improved safety; investors and industry watchers should look for financing, site selection and firm supply contracts as the next proof points.
