Iten: Solid-State Micro-Batteries and European Energy Sovereignty Analysis

Iten, headquartered in Dardilly, France, is a deep‑tech scale‑up delivering novel solid‑state micro‑battery solutions. Its core value lies in miniaturized, high‑power energy storage developed entirely in Europe. Unlike conventional lithium‑ion cells, Iten’s ceramic solid-state batteries use no volatile liquids or cobalt and are designed for ultra-fast charging and high safety .

This allows autonomous sensors and wearables to achieve “endless” battery life (through energy harvesting) without sacrificing peak power. Such capabilities position Iten at the cutting edge of energy storage, with industrial‐scale production already underway.

This analysis answers: What solid-state ceramic micro-battery technology does Iten deliver, and how does it differ from conventional lithium-ion (no cobalt or volatile liquids, ultra-fast charging)? How mature is its industrial-scale production, and how does it fit European energy-sovereignty priorities? Which dual-use applications (autonomous sensors, wearables, energy harvesting) and partners does Iten target? What capability gaps or dependencies affect Iten's position in European energy storage?
