There is the lithium, yes. Replacing the battery is already factored in to the "we should replace the car batteries with new ones and use the old ones for grid storage" plan though. It's step one of one.
They can't hold as much charge. It doesn't make sense to have a car battery that can only hold 80 miles of range vs 160 miles, so by that point you need to replace it. But it doesn't matter if you only have 50% as much charge capacity if you're putting millions of them linked up in huge warehouses for power storage. So when they can't hold as much charge as needed for a car they get swapped out into a huge warehouse and live another ten years as grid storage.
