Altris reaches new milestone with 160 Wh/kg battery cell

The Swedish sodium-ion battery developer Altris presents a sodium-ion battery cell that has been validated for a best-in-class energy density of over 160 Wh/kg. This makes Altris’ battery cell commercially viable for applications such as cost-efficient and sustainable energy storage systems. The achievement marks an important milestone for Altris, which is now working to scale up the giga-manufacturing of its patented cathode material, Altris Prussian White.

Altris is proud to present a commercial-sized sodium-ion batterycell with its highest energy density to date, amounting to 160 Wh/kg. This achievement is made in a research partnershipwith Northvolt, a Swedish supplier of high-quality battery cells, which intendsto use sodium-ion technology as a foundation for its next-generation energystorage solutions in upcoming markets.

Altris’ sodium-ion battery cells are made from abundant raw materials and free from conflict minerals and toxic elements, such as nickel and cobalt. This while offering an outstanding performance in terms of longer life, more flexible working temperatures and safety.

“At Altris, we want to bring the world better, safer and truly sustainable batteries. Thanks to our amazing team and our strong collaboration with Northvolt, we continue to deliver state-of-the-art sodium-ion battery technology. By reaching an energy density that meets market demand, we have delivered on our roadmap. Now, we have our eyes set on achieving 200 Wh/kg and beyond, while keeping our chemistry pure and sustainable”, says Björn Mårlid,CEO of Altris

“The world has put high hopes on sodium-ion, and I’m very pleased to say that we’ve developed a technology that that will enable its widespread deployment to accelerate the energy transition. It’s an important milestone for Northvolt’s market proposition, but battery technology like this is also crucial to reach global sustainability goals, by making electrification more cost-efficient,sustainable and accessible worldwide”, says Peter Carlsson, CEO of Northvolt.

The 160 Wh/kg batterycell is the latest of several important milestones for Altris. During the spring, the company secured €4.8 million in bridge financing and geared up its management with Björn Mårlid as CEO and Christer Bergquist as CFO and Deputy CEO. In June, the company presented a pure Prussian White cathode material with a capacity of 160 mAh/g, which is the highest capacity declared to date in a Prussian White cathode material made solely from abundant raw materials.

To take further steps on its commercialisation journey, Altris is currently in the process of raising series B financing to scale up giga-manufacturing of its patented cathode material, Altris Prussian White.
