I think you're being massively pessimistic on battery life. We already see that EVs routinely degrade much less quickly than was expected, with states of health better than 85% after a decade. I fully expect many EVs to have plenty of serviceable range at 20 or 30 years of age. And of course, an EV battery is stressed much more than a power grid reserve battery: smaller enclosure, deeper discharges, greater range of temperatures, less effective active cooling, etc. I would expect it to be possible to get 30 years or more out of a static system.
Plus, once it *does* reach end of life, the materials can be recovered and recycled and that will be dramatically cheaper than mining new materials. It's a circular economy that can last for centuries.
