That's still a pretty pessimistic view of what the costs would actually be like. We've got pure renewable generation costs that are now pushing $0.015 LCoE. While high efficiency batteries (90% efficient round trip) might cost around your estimate, it would actually be much cheaper to use other forms of energy storage that might be less efficient, but then overprovision on generation to make up for the loss in efficiency.

My calculations assume the wind does not blow at night, that night-time power use is the same as daytime power use even though most people will be asleep, and that storage costs will not continue to decline despite anticipated improvements. It also has the imperfect assumption that storage becomes totally worthless after 4000 cycles instead of gradually degrading, but that degradation starts at the first use and I don’t know the curve so I can’t integrate it to find the total lifetime stored energy, which might be higher or lower than the simplified model I’m giving here.
