Arkema invests in sodium-ion battery firm

Arkema has taken an unspecified stake in its French compatriot Tiamat, a pioneer in sodium-ion battery technology, having also contributed to Tiamat's recent €22 million fund-raising. The company said this is “once again demonstrating its willingness to be a key player in battery materials, offering a unique range of products adapted to all energy storage technologies”.

Tiamat was spun off from the Centre National de la Recherche Scientifique (CNRS) in 2017 and has since been developing, and marketing sodium-ion batteries, an alternative to lithium-ion technology that avoids the constraints associated with the supply lithium. It aims to build a dedicated 5 GWh Giga-factory in France, of which of 0.7 GWh could be operational by the end of 2025.
