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.

I believe you mean mass, not space if you cite the energy density per kg.

Technically correct (best kind) but in reality, to get the same capacity, you'll need more mass, which uses more space as well.

Well, it is a big difference when we are talking about applications like air or space travel where space might be a lot easier to increase than the capacity to carry extra mass.
