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.

" but not the current generation chemistry batteries."

Check for "Saltwaterbatteries", they are starting to reach consumer markets and literally cannot burn as the energy is stored as ... salt water.

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.

Yeah, I'm not saying it's a good idea. But you could do it if you wanted to.

A sand battery would work[0] if you have the space ;)

LFP should be about as safe as other stuff people tend to store in their basements.

LFP's biggest issue is people aren't used to "Phenomenal Cosmic kW/h... itty bitty living space!" Yet.

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.
