In a statement, Northvolt says its validated cell is more safe, cost-effective, and sustainable than conventional nickel, manganese and cobalt (NMC) or iron phosphate (LFP) chemistries and is produced with minerals such as iron and sodium that are abundant on global markets.
It is based on a hard carbon anode and a Prussian White-based cathode, and is free from lithium, nickel, cobalt and graphite. Leveraging a breakthrough in battery design and manufacturing, Northvolt plans to be the first to industrialize Prussian White-based batteries and bring them to commercial markets.
Reports across the web also say the technology enables the supply chain to become ecologically more sustainable, cheaper, abd less dependent on China.
What’s the use case for these batteries? Comments below indicate that they have a lower energy density and use a cyanide compound, which means that they won’t be for personal devices (form factor and safety!). Is the intent for grid scale storage from renewables? Would safety still be an issue (is there any way the cyanide could be evolved off as a gas due to over heating, over charging, etc?)
yes. grid scale storage is always what I heard from these where inexpensive beats density because volume difference is of little concern. In addition it keeps it from using up lithium that is necessary for other uses.
