The batteries chemistry has not improved that much but the density still improved. We were in a period where cost and manufacturing improved far faster then chemistry. But thanks to the investment in batteries there are improvements to the chemistry coming down the pipe.
Tesla is gone have DBE technology that should improve density by 10-20% at least. Full silicon anodes are being commercialized right now. Single Cristal Cathodes are gone come pretty soon. Thicker anodes are being increasingly worked on.
I think we are going to continue to go down the cost curve, both because of engineering and chemical improvements.

Where is that happening exactly? In all the fuel cell cars Toyota isn't selling very well?

It is happening everywhere simultaneously. Right now, tens of billions of dollars are being invested in hydrogen and fuel cell technologies. Anyone who pays attention knows that the revolution is happening as we speak.
I'm curious what this is based on. Last I checked, the li-ion batteries of today are basically the same from the ones we had 10-15 years ago. Sure, a little more silicon, a little less cobalt, but ultimately the same chemistry.
The biggest change for fuel cells is that they're moving from science project to mass production. There will be easily orders of magnitude reduction in cost. While this won't go forever, for the foreseeable future we should see a much faster rate of change for fuel cells and not batteries.
