Given that the batteries are expensive due to scarcity of the materials used, I think we would be better off actually tearing the used batteries down and using the material to build new batteries. Scarce materials really shouldn't be used in stationary batteries. Batteries using plentiful cheap materials should be used instead. These are going to be bulkier, and probably heavier as well, but that's really not important for stationary batteries. E.g. Sodium ion batteries instead of Lithium ion. >Here is an interesting variation on the idea of using EVs as distributed >generators: > >https://www.renewableenergyworld.com/storage/end-of-life-ev-battery-packs-find-a-new-use-as-stationary-storage/ > >End-of-life EV battery packs find a new use as stationary storage > > >Second-life energy storage system Smartville said it deployed its first >commercially available product, the MOAB energy storage system, at the >University of California San Diegos Library Annex. > > >MOAB both integrates and controls repurposed electric vehicle battery packs >from different manufacturers in one unified system. . . . > > >The company said that most batteries retired from electric vehicles retain >70% of their storage capacity, making them candidates for stationary >storage before being recycled. Cloud storage:- Unsafe, Slow, Expensive ...pick any three.
