The energy storage revolution, which has already started, will definitely be accelerated with the AES 400MWh battery storage in Long Beach, CA.
The battery storage is provided by Fluence, not Tesla, unfortunately, but just the fact it's being built will force others to adapt or die.

Energy storage will take care of itself. All the battery packs from every EV produced will need to be disposed of at the end of their useful life for EVs. They will either be recycled or repurposed.
If battery tech advances fast enough that it is economic to recycle them into superior batteries this will be the outcome, otherwise they will just be repurposed for storage.
With every new EV produced there is latent storage capacity increasing along with it.
