Here’s the thing: sodium chloride aka table salt is extremely abundant. We are not expected to run out of it in any measurable timeframe, and the effect of sodium mining on the oceans or ecosystems at large is negligible.

Same cannot be said of lithium, which currently forms the backbone of battery tech. It is rare, and its extraction is extremely polluting. In fact, lithium is responsible for a huge chunk of renewable energy’s ecological footprint.

Switching to sodium technology is like switching from silver to sand. It’s just one thing we truly have enough of.
