I want to replace my Lithium home battery, and what I really want to do it to move to one of the new sodium ion batteries..e.g like the one CATL is supposed to have at some point?

Anyone have a good idea when these will be available for consumers?

Bluetti has a small battery pack for now. I think the options for consumers will balloon once CATL mass produce sodium ion cells. Solix/anker, jackery, ecoflow, etc all use CATL cells already.

Na-Ion batteries are not practical for home storage right now. They have a much higher voltage range compared to LFP batteries, so regular inverters and chargers will not work reliably. Nothing insurmountable, but the supply chain is just not here.

Na-Ion cells are great for grid-scale storage because they potentially can go down to something like $20 per kWh. But bulk LFP cells are already at ~$60 per kWh, so their cost is not really a deciding factor anymore.

Why would you replace it? That asset likely has at least 10 years in it if you already have it.

Why? You also need to replace your inverter in that case.

Hopefully never. If they ever do, it means the local government truly doesn't care about you anymore.

Na is basically Li times 30. This is good in that they make really effective batteries. This is bad in that when the battery malfunctions, the energy is released at 30x the rate. So remember when that Telsa caught fire and the driver walked away very scared but ok. If those were Na-ion, they wouldn't be ok...or alive...or recognizable as human. Basically, these are far too dangerous for consumer use. And any grid scale battery will need about a mile of gravel around them to prevent any fires or deaths from explosions.
