It's a little bit of a lot of things - academic vs industrial incentives, tunnel vision, and the necessity to prove 'impact' for grants. Pretty much every paper will claim something pretty extraordinary is now possible. I mean, why publish a paper on a battery technology if it isn't going to upset Li-ion or revolutionize grid storage? I'm not familiar with this specific instance but GP's point is exactly the sort of technical oversight or omission I'd expect.
