Yes, it's too good to be true.
There was a debuking video about such batteries, but I couldn't find it again.
There was another battery, using radiactive element, promissing a life lasting of charge, but it was for very low power, and just a prototype proposal, for electronic hand devices. Is that possible in theory?
Edited... This was the video, I supose :
But Mr Goodenough new proposal wasn't said to be about 10x more energy, but the solide lithium or solidium was said to be 2x times the energy density o lithium.
The 10x proposal was from the guy, from a company.

Nope I'm calling BS on that.
The most energy dense chemical storage know to man that isn't too weird and could be useable is to oxidize aluminum with oxygen from the air. It's about 4 or 5 times the energy density of lithium batteries.
So when someone one says "my battery is 3, 5 or 10 times more energy dense than current batteries" the laws of physics say you should be skeptical.
