It's not like lithium-ion batteries have a fixed number of cycles. It depends heavily on how you use them. At reasonable temperatures and keeping within 30-70% SOC they last a lot, lot longer than if you use them fully or at elevated temperatures. For something like a big battery station, you can easily ensure the optimal battery conditions for long life. And then there's using alternate chemistries as mentioned.
