Lacroix Assesses Iten's Solid-State Battery Technology for Industrial Feasibility in France
Iten, a Lyon-based company specializing in microbatteries, has engaged Lacroix to evaluate the industrial feasibility of its solid-state battery technology as a sustainable alternative to non-rechargeable button cells. The assessment, conducted at the Symbiose factory, aims to showcase France's potential in localizing strategic energy storage technologies, with preliminary results indicating successful integration of the technology into Lacroix's processes.

Iten, a Lyon-based deeptech company specializing in microbatteries, has tasked Lacroix, an electronics group from Nantes, to evaluate the industrial feasibility of a new energy storage technology as an alternative to non-rechargeable button cells, amid stricter European regulations. The assessment is taking place at the Symbiose factory in Beaupréau-en-Mauges, which opened in 2022.
This technology utilizes solid-state ceramic devices (SSCD) that are rechargeable, cobalt-free, and solvent-free, manufactured in France. The aim is to demonstrate France's capability to locally industrialize strategic energy storage technologies, currently dominated by Asia.
Preliminary results indicate success, with Lacroix (projected revenue of €636 million in 2024) successfully integrating Iten's SSCD into its electronic assembly processes. Additionally, the industrialization of a socket for mounting these components has been validated.
