Can someone with a science background help me- is this a break through for lithium batteries or discovery of Germanium batteries....

The anode of the battery is a germanium based material.........
Hype. Or at least premature. Little practical gain after a few years work.

Note the comments at the bottom.
You had to know the Germans were somehow involved.
