Our cathode material is a framework material consisting of sodium, iron carbon and nitrogen. The large pores inside the material enable the capture and storage of a range of atoms or molecules making the compound highly interesting for a range of applications.

Altris has developed a method to produce Prussian White in a form that is ideal for use as a positive electrode material in sodium ion batteries. Utilisation of the iron as a source of electrons and completely filling the material with sodium provides a theoretical capacity of 170 mAh/g and average voltage output of 3.2 V vs sodium.


Our cathode material is produced via patented low temperature and pressure synthesis route, in a fully-sodiated form, obligatory for application as a cathode material. Altris can produce and sell the material for application as a positive electrode material, for fundamental research purposes or for other applications such as photochromic windows.


The positive electrode material produced by Altris offers a low cost, sustainable alternative to other electrode materials without sacrificing performance. Rapid implementation into existing battery production lines ensures that our product is a “drop-in” solution.
