Ask HN: Are Batteries Not Evolving?

For years that I hear about new developments in batteries but the feeling I got is that everything is pretty much the same: bigger batteries and more efficient CPUs/systems/hardware are making the difference, not the battery itself.

If I do a quick search, I find articles making reference to technologies like graphene, next-generation lithium or charges in 5 minutes, but I just don’t see real applications of all of these. Am I missing something?
