So comparison is about the "amount of energy", not about mechanisms...
If they get this to work, they will just build something with 100x or 1000x the output.
The number isn’t really important here, some indication of how the development of the technology is coming along is what we care about. Compare this energy to the last best output.
If this works and we productionize it, we will suddenly go from 1/4 Tesla battery to 10,000 Tesla batteries.
