There are cylindrical cells available. The capacity is pretty low, 18650 cells are around 1.5AH and 26700 cells are around 3.5AH. They discharge down to 1.5V, so you will get less capacity if you use them in something designed for lithium cells.

Well I’m all about developing new technology and allowing the very best to sell the most.
Maybe someday in the future there will be an alternative to lithium batteries that really is better. But as you said, Sodium batteries aren’t as good.
RaoulDook@lemmy.world 10 months ago
They are actually better than Lithium in several ways. Sodium batteries have most of the capacity of Lithium batteries by weight, around 80% if I recall. But what they have to offer is being completely non-flammable, tolerant to wider temperature ranges, and they are made of materials that are cheap and abundant almost everywhere. It’s much better than having to source Lithium and Cobalt.
We could put Sodium batteries everywhere to power the grid since they are super safe, should be fine outdoors even.

Ok, so that sounds good for grid size battery packs and backyard generator replacements as well as indoor wall packs.

All depend on which point you compare. Because for charging, sodium win over lithium.

Just make a flat battery and roll it up. 🧌

Material scientists hate this one trick.
