Sodium ion batteries have less energy density as opposed to Lithium ion (100-150 WH per Kg instead of 150-250). I'm curious how much these "wet" batteries improve that. The article doesn't say.

Nonetheless, even if it's not the new battery for your car, it could be useful as energy storage for the grid, storing green (solar) energy for the night, and desalinating seawater at the same time.

We hear about a new battery chemistry like every week. Do most never get to commercialization?

They mostly these articles are showing new avenues for research. Most are deadends usually due to issues with production/scalability.

Sodium Ions batteries are coming to market, however the issue is that Lithium Ion are just improving faster and making it harder for Sodium Ion batteries to compete.
