Tiamat: a sodium-ion gigafactory

opens in Hauts-de-France

Another first in Hauts-de-France! Tiamat, a start-up specializing in sodium-ion technology, has chosen Amiens as the location for its production plant. A new structuring project for Europe’s e-mobility sector.

Launched in 2017, Tiamat is an Amiens-based startup dedicated to the design, development and manufacture of sodium-ion batteries, a research topic at CNRS, UPJV and UTC Compiègne for over 10 years.

Following several rounds of fund-raising and the entry into the capital of major groups such as Stellantis, Arkema and MBDA, the startup is now moving on to the industrialization stage and aims to conquer the European market.

We’re going to move into the industrial stage and build our first real sodium-ion battery factory by 2025. This production unit will aim to produce between 500,000 and 700,000 batteries per day. Ultimately, this should create around a thousand jobs, which our start-up, which currently employs 20 people, is delighted about.

A structuring project, which will ultimately require an investment of over 500 million euros.

Commissioning of the gigafactory is scheduled for late 2025 for phase 1, and until 2029 for phase 3.

With its sodium-ion batteries, Tiamat is targeting the following markets:

• mobility
• stationary storage of energy (wind or solar)

The main material used in Tiamat batteries is sodium.

6th most abundant element on earth, its use reduces the need for rare strategic materials such as lithium and cobalt.

An innovative technology, fully committed to the Rev3 regional dynamic.

As a result, our batteries are more durable – with a lifespan of 10 years compared with 3-4 years for lithium batteries under conditions of continuous use – and 10 times faster to recharge (in just 5 minutes). And at a cost equivalent to lithium-based technologies. It’s an ecological, economical and reliable alternative.
