Altris is a Swedish company who has discovered a new way to produce a sodium based cathode material using only renewable materials. This world-changing discovery enables a new generation of batteries that are not only friendly to the environment but also cheaper to produce than it’s competitors.

Altris specialises in producing highly sustainable cathode materials for rechargeable sodium batteries, enabling rapid integration of renewable energy sources.

Altris was founded on the idea that in order for a truly sustainable future to be realized, safer, environmentally friendly batteries free of toxic or expensive compounds are vital. We believe that batteries should enable renewable energy sources without sacrificing customers money or the environment. This is why we produce the first positive electrode material made from completely renewable, low cost materials.


Our cathode material consists entirely of sustainable components. There is no lithium, nickel or cobalt and bringing benefits such as price and supply stability and with no negative social or environmental impacts.

Low Cost

The product only consists of highly abundant materials, derived from low-cost precursors and produced via a low energy production process. This enables the production of cheaper batteries on a scale not currently possible.


Our product provides cost and sustainability benefits without sacrificing performance. With a theoretical capacity of 170 mAh/g and average voltage output of 3.2 V vs sodium, the material is on par with equivalent lithium technologies.
