Can be a battery, but not a very energy dense one.

I think water purification might be the most interesting application.

Second most interesting is ion concentration, but there are other ways to do that, e.g. https://www.youtube.com/watch?v=eq7fR9ISuCw

But this doesn't require conductivity so it allows you to concentrate ions without adding salt - which is why it works for water purification.
