The Tesla giga factory produces 35GWh of batteries per year. It would take ~14 years for a giga factory to produce just one hour's worth of storage. We need days at least, potentially weeks depending on the mix of renewables. Again, the scale just isn't there for batteries.
This is why renewable evangelists assume something like hydrogen storage, or compressed air will deliver nearly-free storage. But that's just hope, who knows if these approaches will actually be competitive.
