Tiamat Energy, established in 2017, emerged as a spin-off from the French National Centre for Scientific Research (CNRS) and University research units within the RS2E network. The company develops and manufactures sodium-ion batteries for mobility and stationary energy storage applications. Its innovative approach focuses on creating sustainable energy storage solutions that address current market challenges by utilizing sodium, a more abundant and cost-effective alternative to lithium. Since its inception, Tiamat has positioned itself as a significant player in the European battery manufacturing sector, with plans to establish large-scale production facilities.
Battery Technology
Tiamat’s sodium-ion battery technology represents a significant advancement in energy storage solutions. The company offers two distinct generations of batteries, each designed for specific applications. Their Gen1 batteries excel in high-power applications, delivering 90-110 Wh/kg capacity and supporting high discharge rates of 30C continuous and 100C pulse. These batteries demonstrate exceptional durability, lasting over 5,000 cycles.
The Gen2 batteries focus on medium energy density applications, providing 140-160 Wh/kg while maintaining cost-effectiveness. Both generations utilize abundant materials and eliminate the need for lithium and cobalt, reducing supply chain risks and environmental impact. The technology demonstrates superior safety features and fast charging capabilities, making it suitable for various applications, from power tools to electric vehicles.
The manufacturing process incorporates advanced techniques that ensure consistent quality and performance. Tiamat’s batteries are designed to operate effectively in both mobility applications, including hybrid vehicles and fuel cell systems, and stationary storage solutions such as uninterruptible power supply systems and data centers.
Recent Projects
In early 2024, Tiamat secured €30 million in funding for its planned gigafactory near Amiens, France. The company aims to raise an additional €120 million to complete the facility, which will have an initial production capacity of 5 GWh of first-generation sodium-ion cells. The first phase targets an annual capacity of 700 MWh by late 2025. Tiamat also formed a strategic partnership with battery system manufacturer LEAD to facilitate its transition to large-scale production.
Investors
Tiamat has attracted significant investment from major industry players. Stellantis Ventures, the venture capital arm of the automotive manufacturer Stellantis, has provided strategic funding to support sodium-ion technology development. Additional investors include Arkema, a materials science company, MBDA, a defense equipment manufacturer, and Bpifrance, the French national investment bank. These partnerships strengthen Tiamat’s position in the battery manufacturing sector and support its expansion plans.
