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.

Isn't Prussian white super rare too?

It's a natrium-iron cyanide salt. Probably poisonous, not any harder to produce than any other industrial chemical, as long as you automate the process.

Maybe it's not easy to produce, but Na2Fe[Fe(CN)6] doesn't seem like it has any rare raw materials (but I'm a layman and just googled it).

Iron, carbon, and nitrogen? It’s been produced for hundreds of years.

Isn't that one of the colors Bob Ross was always using?
