I really doubt that battery plants for longer duration storage will be lithium based, something redox-flox based will be the future. But with batteries (especially grid scale, where energy and power density matter much less) there are a multitude of feasible options, some more, some less economic, which means in case of material shortages we can switch in the medium term. I also think hydroelectric storage is an underappreciated opportunity, which, if there is a serious issue with chemical battery supplies, could be reasonably quickly expanded. It's also silly to use batteries as base load, as is the concept of base load in general in combination of cheap, but non-dispatchable, renwables, which is one of the things that hurts the economics of nuclear plants.
