The world has plenty of lithium. Just takes a couple years of mining to catch up.

There’s also a limitless source in the ocean. If prices got high enough we could just filter ocean water.

At what concentration though? At what price does lithium extraction from Sea water become economically viable? It feels to me that this is an entropy problem.

AFAICT, Lithium extraction from sea water is economical at current prices. What's preventing its mass adoption is the certainty the prices will stay at current levels.

There's also sodium, which makes for almost as good batteries for much cheaper.

Not for use in motor vehicles. Very good for infrastructure though.

No, they are great for cars. For infrastructure iron batteries are much better. Iron batteries are not suitable for cars though.
