Lithium vs. Sodium - Is That a Good Idea?

Sodium is so much easier to access. And I think the US has ridiculous, I think the biggest reserves of sodium in the world by orders of magnitude. Yeah, and then that's the prime thing. People also point to like the fast charge capabilities of sodium ion. But my concern would still be, okay, so you're dealing with lithium versus sodium, which has an incant weight advantage,. Because each lithium ion is going to be much lighter than sodium.
