Cheaper, more environmentally sustainable, and safer to ship, sodium-ion batteries could one day replace lithium-ion in a range of places.
While not as energy dense, sodium is much more abundant than lithium, so could remove much of the strain on precious metals as we keep electrifying.
How similar are sodium-ion and lithium-ion batteries?
Sodium is in the same column in the periodic table, one below lithium. It’s got similar properties, but its [atoms are] much bigger and heavier and there also some really clear chemical differences.
Manufacturing-wise, it’s a drop-in technology. If you can have a manufacturing plant that can make lithium-ion batteries, you can swap in sodium-ion batteries.
