Electrical Storage

Anyone able to pluck some figures out of the air for the efficiency of converting electricity to heat and then back to electricity again?

(Based on the idea that molten salt at solar plants is apparently very efficient for concentrating and storing the energy that's being collected. Could it be used as a battery in general?)
