I’m so desperate for home battery using sodium batteries. Safer and lower temperature it can operate at. Low energy density but I don’t care for home battery.

Every day, there's another news story about it... Just let me know when we can actually buy it. It's getting boring already.

Just imagine: ALL the money that flew into "Fossil & Co" throughout the last, lets say, 50 or 60 years, including all implicit fundings, like state-building-streets or universities-masters-engineering-focus-ICE, all the money for lobbying, all the money for all the (counter)campaigns (from ALL sides), and all that money.... ...WHAT IF we would have spent all of this money instead on Battery Research and all this Renewable Energy stuff? Where would we be today on techdev curve? ;-) ;-)

I switched the 12v lead-acid batteries on my EV to the 12v Lithium from OHMMU. Best upgrade I've done. I recently saw that they now offer 12V Sodium, and their warranty now went up to 3 years on the sodium, from 1 year. They have new data on its robustness.

That was fast. CATL is only now ramping up Naxtra production and it's already approaching price parity with LFP. This is early validation of the cost curve predictions for this chemistry. Most of this is destined for stationary storage that would likely have used lithium-based chemistry instead, or not been built-out at all. Every GWh of capacity sodium offsets is a GWh that isn't supplied by lithium, so demand for higher-value battery chemistry should be lower, and take prices with it. Good news all around.

> approximately $200/kWh for LFP batteries Huh? Automotive grade are like 50 and storage ones are like 30. Can someone confirm these prices because sounds a whole lot of BS or article not saying something (i.e. dancing around TCO).

mere cost parity seems kind of disappointing. I thought the main selling point (other than low temp) was supposed to be that it was cheaper.

I've probably drunk too much kool-aid somewhere else, have always assumed sodium-ion batteries are already cheap and it's just trying to beat LFP in terms of energy density...
