There were literally hundreds of exactly those articles I read or skimmed through in the past, none of them made it to mass market. It's almost as if there might be an underlying scam that produces these research hypes to grab investor money or something. Until the real problems are adressed, or looked at and then the research ceases.
I mean I really hope there are some leaps in battery technology soon, as many do, because it does not hold up at all to moore's law as it is kind of needed for mobile devices to progress as fast as silicon or other advancements. I just don't care for misleading articles anymore :)
