12 January 2024

Key highlights

Arkema invested in Tiamat's €22 million fund-raising.
Tiamat aims to build a 5 GWh Giga-factory in France.
An initial 0.7 GWh tranche could be operational by end of 2025.
Sodium-ion batteries avoid lithium supply constraints.

Investment and Stake Acquisition

Arkema has acquired a stake in Tiamat, a start-up that emerged from the CNRS in 2017 and specializes in sodium-ion battery technology. This investment aims to accelerate the development of technical solutions for these lithium-free batteries.

Technology and Development

Tiamat has been focused on designing, developing, industrializing, and marketing sodium-ion batteries since its inception. These batteries offer an alternative to lithium-based technologies, addressing supply constraints associated with lithium.

Funding and Strategic Partners

Alongside strategic investors like Stellantis Ventures and MBDA, Arkema contributed to Tiamat's recent €22 million fund-raising. This financial boost, supported by the French government and the European Union, will help Tiamat scale its operations.

Future Plans

Tiamat plans to build a 5 GWh Giga-factory in France dedicated to sodium-ion battery cell production. The first phase, with a capacity of 0.7 GWh, is expected to be operational by the end of 2025. The project could eventually create up to 1,000 jobs.
