ITEN S.A.

What ITEN S.A. does

ITEN S.A. is a French deep-tech industrial company founded in 2011 and headquartered in Dardilly, near Lyon, France. The company designs and manufactures solid-state ceramic lithium-ion microbatteries built around proprietary full-ceramic Li-ion electrodes and nanomaterial architectures. Its microbatteries deliver a 200C discharge rate — 40 to 100 times higher than conventional lithium-ion cells — enabling sustained milliwatt-level power output in ultra-compact form factors. ITEN holds more than 200 in-force patents and has invested in R&D for over 12 years, supported by 40+ engineers and PhDs on staff and a long-standing research relationship with CNRS formalized through the LabCom AMIE joint laboratory with ENS de Lyon, Université Claude Bernard Lyon 1, and ANR. Mass production of its first-generation solid-state ceramic microbatteries began in May 2025, marking a transition from R&D to commercial-scale output.

The company operates a B2B sales-led go-to-market, selling directly to OEM manufacturers and industrial buyers under negotiated contracts (FCA Dardilly, France) with payment terms of up to 30 days net. Pricing is not publicly disclosed and is determined by order specifications and volume. ITEN targets four horizontal application segments — IoT devices (asset tracking, smart sensors, smart meters), wearables (including AR glasses and smart contact lenses), healthcare and biomedical devices, and power backup systems — all requiring miniaturized, high-power, hazard-free energy storage. The only publicly named customer is XPANCEO, a UAE-based partner co-developing a proof-of-concept AR smart contact lens.

ITEN monetizes through hardware sales of its microbatteries, which integrate as Surface Mounted Devices (SMD) on standard electronics manufacturing lines. The company is RoHS-qualified, free of hazardous liquid electrolytes, and controls its full manufacturing process in-house from nanomaterial synthesis to final testing. Capital structure is private and venture-backed, anchored by a €80 million round closed at end-2022 with BPI France, Groupe SEB, Innovacom, EREN Groupe, and Habert Dassault Finance. The company has received the CES 2024 Best of Innovation Award and three consecutive French Tech 120 designations (2023–2025).
