[RE-wrenches] Sodium Ion vs Lithium Article

[Zeke Yewdall]

I have a small sodium Ion battery that I built last February and its
voltage is a bit wider than LFP or LTO, but not nearly as bad as Nickle
Iron, and not as bad as aquion either.  Probably not even as bad as
flooded lead acid honestly.  So, any inverter than can handle flooded lead
acid should be okay with them from what I've seen from my little 20AH test
battery.

When I built mine, prices were still a bit higher for Sodium ion compared
to LFP cells, and 20Ah was the largest cylindrical cell I could even get.
I think I saw some larger prismatics available now, can't remember the
price though.  And I have seen a few commercial batteries in addition to
cells. Bluetti has a power station using sodium ion now.

I've heard that the voltage range of the available SI batteries is very
wide, which might make their use with current inverters in our field
difficult. Sort of like the Aquion battery.
