Tiamat Energy is a French technology company specializing in the development and commercialization of sodium-ion battery cells as a sustainable alternative to lithium-ion batteries.[1][2][3] It builds two generations of batteries: Gen1 for high-power applications like power tools, off-road mobility, and stationary storage, and Gen2 for medium energy density needs in electric vehicles (EVs), stationary energy storage, and 2-3 wheel vehicles, targeting over 140 Wh/kg initially and aiming for 160 Wh/kg.[1][3] Tiamat serves industries including mobility (road, rail, marine, air), power tools, and energy storage for smart grids and data centers, solving key problems like lithium/cobalt dependency, supply chain vulnerabilities, high costs, and geostrategic risks through abundant sodium materials for price stability and sovereignty.[1][2][3][6] The company has achieved early commercial traction with a multi-year supply contract for power tools (Dexter Leroy-Merlin range)—a global first for mass-commercialized sodium-ion batteries—and is constructing a 5 GWh gigafactory near Amiens, France, with first volumes in Q1 2026.[1][2][3]
Growth momentum is strong, backed by investments from Stellantis Ventures and partnerships like Endeavour for AI data centers and grid applications, leveraging ultra-fast charging (60 C-rate) and cycle life tested on real-world workloads.[5][6]
Tiamat Energy was founded in late 2017 as a spin-off from nearly 10 years of academic research by the French National Centre for Scientific Research (CNRS) and university units within the RS2E (Réseau sur le Stockage Electrochimique) framework, headquartered in Amiens, France.[1][2][3][4] The idea emerged from CNRS-led innovations in sodium-ion batteries to address lithium-ion limitations, transitioning from lab research to commercialization.[2][3][4] Key early milestones include sharing evaluation samples since 2019 with major players across market segments, securing the world's first multi-year sodium-ion supply contract for power tools in recent years, and receiving a Stellantis Ventures Award in 2023 as one of 11 top startups.[1][6] These steps built pivotal traction, enabling plans for a gigafactory in the ZAC Jules Verne 2 area.[2][3]
Tiamat rides the sodium-ion battery trend as a response to lithium supply shortages, rising EV/storage demand, and decarbonization goals, offering a timely alternative amid geopolitical tensions over critical minerals.[1][2][6] Timing is ideal with global electrification accelerating—e.g., BEVs, AI data centers, renewables—where sodium-ion's local sourcing supports EU sovereignty and nets zero targets like Stellantis' Dare Forward 2030.[3][5][6] Market forces favoring Tiamat include abundant raw materials, lower costs, and superior power/safety for underserved niches like fast-charging grids and hybrids, influencing the ecosystem by pioneering commercialization, spurring regional jobs via its French gigafactory, and partnering with giants to integrate into AI infrastructure and mobility.[2][5] This positions sodium-ion as a complementary technology, diversifying battery options and accelerating sustainable energy transitions.[2][6]
Tiamat is set to launch gigafactory production in Q1 2026, scaling to 5 GWh annually and expanding Gen2 for broader EV adoption, fueled by investments and partnerships like Stellantis and Endeavour.[1][2][5][6] Trends like AI-driven grid volatility, renewable integration, and mineral independence will propel growth, potentially evolving Tiamat into a key sodium-ion leader by 2030 with 48 GWh capacity plans.[3] Its influence may expand through global supply for data centers and mobility, solidifying France's role in battery tech and delivering on the promise of sovereign, affordable electrification that began with CNRS research.[2][3]
Tiamat has raised $9.0M across 1 funding round. Most recently, it raised $9.0M Series A in February 2023.
