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.

    the strategy of retaining crystal interlayer water yielded a specific capacity of 280 mA h g−1 at 10 mA g−1, one of the highest capacities reported for SIB cathodes in literature. All I could find. This isn’t a statement about capacity(?) Units are wrong(?) Its worth noting how preliminary this research is. Currently these “batteries” are just jars with chemicals. pubs.rsc.org/en/Content/…/D5TA05128B www.rsc.org/suppdata/d5/ta/…/d5ta05128b2.mp4

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

    My very uneducated understanding is that sodium batteries can be produced virtually anywhere. Not every battery application needs to maximize energy density, so sodium batteries are good where that is the case. I also did not read about sodium ion batteries characteristics versus lithium ion, so there might also be other use cases where sodium ion batteries are better.

    Exactly this, there's a huge market for energy storage, where cost, power and cycle life matter way more than size and weight. And Na-ion can be produced in countries that do not have access to lithium mines, making transport less of an issue and countries more self-sustaining.

    There is a branch of battery research that is only focused on grid storage. It's the last piece to make solar and to a less extent wind unbeatably affordable. In a home solar setup, batteries are the other half of the cost and have not fallen as fast as the cost of the panels themselves, the other half of the cost. For fully off grid setups, they quickly become the main cost.
