I believe this is the paper: http://pubs.acs.org/doi/full/10.1021/acsenergylett.6b00029 http://pubs.acs.org/doi/full/10.1021/acsenergylett.6b00029 The headline, while not outright lying, is clearly playing on ambiguity to suggest a more sensational story The "student" is a doctoral student with multiple previous publications (and not, say, a 17 year old high school student) "Lasts 400 years" refers to the battery's potential ability to withstand a very high number of recharge cycles while maintaining capacity (and not, say, that it can supply energy from a single charge for 400 years)

> Lasts 400 years Still a lot better than 3-5 for existing techs. The battery would essentially be immortal. Perfect for large scale deployable for national power grids.

  3-5 years under ideal conditions. Stick a battery in a phone/laptop that regularly gets used in the heat and it will give up the ghost within a year. It's not even so much the ultimate lifetime that matters so much as the longer 95% capacity life, which is much shorter now. I wouldn't be surprised if this also has some major catch, like manufacturing cost, heat degradation, or instability under mechanical stress. So while it could be an really important discovery, I'll remain skeptic until I have a laptop battery that lasts for longer than 12 hours after a year of heavy use in a hot, humid climate.

    All phones I had lasted at least 3-4 years of constant extensive use. In my Samsung Omnia, I had to change a battery after 3 years just and I was using a lot of it - especially as a GPS unit. The battery fault was also my wrongdoing in this case.

  We'll have fusion before we have mega scale solar.

The news is also 4 months old. Original press release (unfortunately sans 'Bermuda Triangle scary secrets discovered? what do we know?'): https://news.uci.edu/research/all-powered-up/ https://news.uci.edu/research/all-powered-up/. The sheer laziness of the article to not even link to the PR release is amazing.
