We are a Swedish company that has discovered a new way to produce a sodium based cathode material, using only renewable materials. Our groundbreaking discovery enables a new generation of batteries that are not only environmentally friendly, but also cheaper to produce.

Altris specialises in producing highly sustainable cathode materials for rechargeable sodium batteries.

Altris was founded on the idea that in order for a truly sustainable future to be realised, safer, more environmentally friendly and affordable batteries are vital. This is why we produce the world’s first high performing¬†cathode¬†material made from completely renewable and low cost materials.¬†


Our cathode material consists entirely of sustainable components. There is no lithium, nickel or cobalt. This approach ensures supply stability, without any negative social or environmental impacts.

Low Cost

Our product is made from highly abundant materials, derived from low-cost sources and produced via a low-energy production process. This enables the production of lower cost batteries.


Low-cost and sustainable, without sacrificing performance. With a theoretical capacity of 170 mAh/g and average voltage output of 3.2 V vs sodium, our material is on par with equivalent lithium technologies.
