Why do you think Lithium is running out? There is enough Lithium that could be mined if there was enough political will (and sometimes price signals).
Besides, we might also use other battery types, such as Redox-Flow for long term storage.
The current “backup” plan is to produce Hydrogen or P2G continuously, store it, and use it in cheap, inefficient gas turbines for the week every few years (without large grid interconnectivity) where there is a prolonged Dunkelflaute.

In Germany we already often have more energy than we can use and wind turbines have to be shut down so the power grid doesn’t get overwhelmed. What we need most right now (here in Germany) is more grid expansion and not necessarily more energy production. Also, not every store of energy has to be lithium batteries.

In fact, sodium batteries seem to be taking off and the only downside they have compared to lithium batteries is battery density, which isn’t a problem for grid storage.
