alt Hacker NewsI’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.

I want to have viable replacements for all the old school lithium ion battery packs so that I won't wonder when the day will come that one of the many we have will experience thermal runaway while nobody is around to deal with it. IMO a world where we no longer worry about spontaneous battery fires can't happen soon enough.
There is an aqueous variant of sodium ion batteries that are safer than lithium, but most sodium ion batteries are NOT that variant and are more dangerous than LiFePO4.
I thought the main advantage in comparison with LFP is the lower price(long term) and better sub-zero performance?
Sodium batteries will only continue to get cheaper. Cost parity now, but probably closer to 1/2 the price in a few years as production ramps up.
