Sustainable high energy density cathode material for stationary storage solutions

Altris produces a high energy density cathode material for rechargeable batteries via a low-cost production method using only abundant elements. The material is a drop-in solution that readily works with existing technologies, which thus enables the rapid adoption of a truly sustainable rechargeable battery for stationary energy storage applications.

The need

The battery production industry has a need for low-cost, sustainable electrode materials that are free from nickel, cobalt and lithium. Furthermore, batteries capable of low temperature performance are in strong demand.

The solution

Altris has a patented solution for producing a practical cathode material for sodium batteries that is free from nickel, cobalt and lithium. Its elements – sodium, iron, carbon and nitrogen – are accessible, economical and pose no health or environmental hazard. The production process runs at low temperatures and pressures, saving both energy and raw materials. Unlike lithium ion batteries which generally fail below 0°C, the new material enables reliable sub-zero performance.

The value proposition

The company’s high energy density cathode material is one of the few electrode materials that is truly eco-friendly and comprises entirely abundant elements. It is low-cost, non-toxic, operates at low temperatures and its cost-effective, equally eco-friendly manufacturing process can be incorporated into existing battery-plants with no modifications to existing equipment. Batteries constructed with this material can be safely transported in a discharged state.
