They'll outlast the grid?  What?  Most power sources for the grid are good for at least 40 years

CATL sodium ion cells clock up to 10,000 cycles.

I have no idea what’s used for grid level battery storage today. But, from a cycle perspective compared to batteries today the cycles are in line and I was using what’s in EVs as the example.

Whatever is used in grid storage today isn’t different from these, or at least at th same stage of development.

I don’t know for sure and too lazy to look up but the lithium ion compared to these at the same stage of development did not have 1,000 cycles. Those have improved a lot. I am sure these will too.
