> It's a bad battery.

I think there are use cases where it's a very good battery if small enough devices are created. Specifically, an empty cell on its own is going to be much cheaper than a lithium battery. I could swap and store many cells in my garage, but I can't do that with a typical mounted battery. This means the capacity of cells would be limited by physical storage space. And if my solar system produces a lot more electricity that I could use on a normal day, it could make sense for a rainy day.
