From the article:
"The material the research team focused on was Li8/7Ti2/7V4/7O2, a binary system composed of optimised portions of lithium titanate (Li2TiO3) and lithium vanadium dioxide (LiVO2). "

and

"This cell exhibited a remarkable capacity of 300 mA.h/g with no degradation over 400 charge/discharge cycles."

No degradation is pretty impressive, current EV batteries are about 2% of max per year. After 5 years you’re driving 10% less miles between charges, which forces more charge cycles.

It's not really like that. Well-looked-after batteries see steeper initial loses and then much slower further losses.

So much for cheap and readily available materials. But that capacity is impressive
