What this report covers
Technologies: Autonomous Systems, Robotics & Swarms, Energy Storage, Propulsion & Power, Additive Manufacturing & Critical Supply Chains. A sourced, structured 11-page analysis for European defence and dual-use decision-makers, from the DFM research desk and built on official and primary sources.
About this report
Tiamat is a French deep-tech startup specializing in high-power sodium-ion batteries capable of ultra-fast charging. Born as a CNRS spin-off in 2017, the company’s core proposition is to deliver cost-competitive energy storage without relying on lithium, cobalt or nickel.
By exploiting abundantly available sodium materials, Tiamat promises a “sovereign independent supply chain” for batteries . This positions Tiamat at the intersection of Europe’s energy and defence priorities: its batteries can power heavy-duty vehicles, drones and grid infrastructure with high charge/discharge rates, while mitigating dependencies on foreign mineral supply.
Key questions this report answers
- What sets Tiamat's high-power sodium-ion chemistry apart from lithium-ion for defence applications that demand ultra-fast charge and discharge rates?
- How credible is Tiamat's claim of a "sovereign independent supply chain" free of lithium, cobalt and nickel, and where do residual material dependencies remain?
- At what technology readiness level do Tiamat's cells sit today, and what industrialisation gaps separate the 2017 CNRS spin-off from defence-grade volume production?
- Which European strategic programmes and industrial alliances is Tiamat aligned with, and how do they underpin the investment case in dual-use energy storage for vehicles, drones and grid?
