Tiamat SAS Overview

Pro stress-test →

Tiamat Energy, founded in 2017 in Amiens, France, develops sustainable sodium-ion batteries for mobility and stationary storage. The company is a spin-off from the French National Centre for Scientific Research (CNRS) and RS2E network university units. Tiamat positions itself as the leading manufacturer of sodium-ion battery cells for power applications, with ambitions to become the reference technology for power needs in stationary, power tools, and hybridization markets.

Strategic Profile

Pro stress-test →

Sodium-ion technology offers lower cost per kilowatt-hour and is free of lithium and cobalt, with abundantly available sodium offering benefits in sustainability and material sovereignty. Tiamat was the first company in the world to have recently commercialized a sodium-ion technology in an electrified product. In early 2024, Tiamat secured €30 million for a planned 5 GWh gigafactory near Amiens, France, aiming for 700 MWh annual capacity by 2025.

Competitive Landscape

Pro stress-test →

Chinese battery giant CATL has unveiled its Naxtra sodium-ion brand and plans a commercial line in 2025, and state-owned carmaker JAC Motors launched an EV with sodium-ion batteries in January 2024. Tiamat competes primarily with Chinese and established lithium-ion manufacturers entering the sodium-ion space, positioning itself on first-mover commercialization and European manufacturing sovereignty. Direct Western European competitors remain limited as the sodium-ion market remains nascent.

Industry Context

Tiamat SAS operates in Batteries.
