I wouldn't want a battery in my basement. if there is a fire in the battery your house will turn into a smoking hole, in the literal sense. Maybe if it was an iron-air battery or something safe, but not the current generation chemistry batteries.
Seems like the peak was around 2017 but they never performed particularly well?[1]
The problem is if the promise from the name was true, they'd be everywhere - they're not, so invariably much like vanadiun-redox or iron-flow batteries it turns out all the other details make them more expensive and less performant.
" if the promise from the name was true, they'd be everywhere"
Not necessarily.
Lithium is still quite cheap, safety is not the number one demand - and it is mainly about optimizing production to achieve competive pricing.
So yes, mabye there are some blocking details I am not aware of, but otherwise I expect their time will come.
Even if it was a safer chemistry, I would still put it outside of my house, likely in a dedicated structure. Its a shit ton of energy potential regardless, and it can make maintenance and modification down the line way easier.
