How long have you been watching this space? Batteries are hard and many many lab-scale advances don't make it. It's still cool to check them out, but skepticism is definitely warranted.
Before i take a real look at a flat earth model it has to at least predict solar eclipses and explain seasons. Before i take a look at 'EV Breakthrough' it has to address everything on this list.
Alternatively, a title less grand then 'EV Breakthrough' is also fine.
