> To power a house for a hundred hours you need a battery that can power 100 houses for 1 hour.

A battery that is meant to power a single house doesn't need to be able to output enough power for 100 houses.

It's important to not be misleading about that because, usually, the lower the rated output of a battery, the higher the power density can be. Which means cheaper and smaller batteries.

I'm not sure I follow. What battery are you referring to when you say a low power density battery can have a high energy density? A flow cell battery?

I'm talking about existing commodity batteries, like lithium ion batteries.
