Endeavour & Tiamat unveil ultra-fast sodium batteries for AI data

Endeavour has announced a strategic partnership with battery manufacturer Tiamat to deliver 60 C-rate sodium-based batteries for data centre and peak shaving applications.

The newly developed battery technology from Tiamat can fully charge and discharge more than 60 times within an hour, significantly exceeding the 1-3 C-rate capability of typical lithium-ion batteries. This ultra-fast charging and discharging capacity, combined with high energy density and long operational life, is aimed at meeting the demands of volatile artificial intelligence (AI) compute workloads and grid management.

Jakob Carnemark, Founder and Chief Executive Officer at Endeavour, said, "We are scaling the next generation of inverters and power routers capable of managing complex AI data center loads and enabling greater grid stability. Tiamat's battery chemistry is unique among other sodium chemistries. The batteries are currently being manufactured and have been tested by Endeavour over the last year on real-world AI workloads and complex grid transients for hundreds of thousands of cycles. We look forward to working with Tiamat to scale the solution globally and continue to support their growth."

Mickael Mauger, Director of Engineering at Endeavour's GridBlock power router division, addressed the challenges faced by existing solutions, stating, "Current UPS systems struggle with AI workloads, requiring additional bulky batteries and supercapacitors that consume valuable IT rack space. Our energy router technology maximizes Tiamat's power and cycling performance to handle demanding AI load profiles. This reduces capital and operating costs."

The batteries utilise a proprietary sodium-based chemistry that eliminates the presence of lithium, cobalt, and nickel. Endeavour highlights that the exclusion of these materials addresses concerns over resource scarcity and the humanitarian issues sometimes associated with traditional battery supply chains. The technology is described as having almost no risk of thermal runaway, a safety consideration that is important for critical infrastructure settings such as data centres.

Hervé Beuffe, Chief Executive Officer at Tiamat, said, "We are extremely pleased with this partnership, which provides long-term support from Endeavour and unique technology collaboration. It marks the culmination of many years of hard work developing our breakthrough technology for power applications. Over the last year of testing, it became clear that our battery technology was the only one currently capable of managing the complex loading and durability requirements that Endeavour's engineers were looking to solve."

Tiamat was established in 2017 in Amiens, France, and has focused on applying academic research to the industrialisation and production of sodium-ion battery technology. Its latest batteries will be used in Endeavour's range of infrastructure technologies, including its Edged data centres. According to Endeavour, access to these batteries will be made available exclusively through its platform to other companies operating hyperscale or data intensive services.

Endeavour's partnership with Tiamat is positioned as part of its ongoing mission to address large-scale infrastructure needs sustainably, with a focus on supporting the energy, water, and IT requirements of cloud and logistics industries.
