Demonstration of production line for recycling of production waste into Fennac precursor

Altris’ vision is to contribute to the energy and climate transition by commercialising the cathode material Fennac for use in sustainable and safe sodium-ion batteries. Fennac-based batteries are free from critical elements such as lithium, cobalt, phosphorus and graphite and all raw materials can be manufactured within Europe.

Today, the production of Fennac uses a precursor and the cost of it is a substantial part of the total production cost. This leads to a high sales price and that Fennac primarily can be sold as a niche product where safety and sustainability are critical aspects. However, during the production, a by-product is also formed and the aim for this project is to recycle this by-product into the precursor that is used for Fennac production.

By doing so, the production costs can be lowered enough to enable Fennac batteries to compete on a large scale with lithium-ion batteries for stationary storage, e.g. connected to solar panels or to wind power plants
