Why do you need such long lifespan for grid storage? It’ll be much easier to service and change out modules in a grid storage plant than in a car. Most likely, when recycling tech is more widespread and efficient, you’ll want to recycle the cells quite often to stay at a high % SoH to get the most out of the material, and to exploit the latest chemistry advancements. Obviously li-ion doesn’t need to get cheaper to be used for grid storage. It’s used profitably for that purpose today. What kind of grid storage are you talking about? Li-ion is already excellent for frequency regulation and short term energy storage. Li-ion has never and will never be a solution for long term seasonal storage. Then you’ll want pumped hydro or other gravity based storage, flow batteries, thermal storage, liquid air battery, etc. I think liquid metal batteries might outcompete li-ion in the end. And they do probably have 30 year lifespans with little to no maintenance. But it’ll be the cost and rapid scalability that’s the critical factor.
