even if the theoretical limits for the new thing would blow modern batteries out the water.

The theoretical limit of energy storage density is extremely close to lithium ion batteries. At least as far as the actual lithum storage medium goes. Obviously there is a non-zero amount of mass in a battery that isn't energy storage, but there doesn't exist even a theoretical substance that would be better at storing energy then current lithium ion tech.
