And then one of the biggest selling points of USB type C is moot - namely its longitudinal symmetry, which allows to plug it in without caring about orientation.
That's the joke.
It seems like we're always hearing about the next big thing in battery technology, but they seem to stay in research forever, and never hit the consumer market. The most exciting part of this, is that they say the'll be in consumer devices early 2017. I'd love to have one in my quadcopter!
Note that having a compressed energy ready for rapid release is exactly equal to handling an explosive in your laptop :) There are a lot of experimental batteries that have like 5x capacity of the current Li-ion ones, but melt and explode when heated or crushed, which makes them effectively useless. This is one of the hardest problems in high-capacity batteries - to avoid "rapid unscheduled heat dissipation" and the…
But that’s exactly what Li-ion batteries already do. x)

As you have it isolated from the house in a specially built enclosure or garden shed it's less likely to get damaged and even if it is the damage can be manageable.
Then again in these cases it's more of a matter of how cheap it is vs the amount of energy it can hold and size doesn't matter a much.
Most of the time these great battery breakthroughs go nowhere because they only manage to demonstrate with a tiny hand-built cell (often as not only presenting the result of the one cell that did finally work out of dozens of attempts), but there's no path to commercialisation.
If they really do ship usable batteries by november this could be huge.

In that case, maybe what's actually needed is not battery capacity, but quicker and more convenient recharging systems? Say solar, kinetic, or wireless charging stations spread throughout a city? Maybe incorporate some kind of "witricity" into the next WiFi proposal? If stuff can be recharged while it's being used, or within seconds, it shouldn't matter how much capacity the battery has.

TL;DR: guy used stock flashlight with two stock CR123 batteries in series. One discharged faster than the other, so it got reverse charged from the one holding more charge, and promptly vented hydrogen gas that got ignited and blew up. Guy got glass and metal shrapnel damage to his foot, and hydrogen fluoride poisoning resulting in permanent lung damage and other bad symptoms. It's really horrible. Bad stuff starts at page 5.

Well, that was a practical joke for over 5 years with USB 2, and I do not find it so funny when plugging in my phone to the charger half sleep at 3 o'clock in the morning.

"Yet just as safe and long-lasting as the lithium ion batteries used in consumer electronics" is not happy-making as energy density increases. The existing lithium-ion technology just barely keeps from overheating and blowing itself up, and it takes about six safety devices to prevent that. (Latest major hoverboard explosion story: [1] All those safety devices really are needed.) Lithium metal batteries (available now as non-rechargeable batteries) are even more dangerous, and are currently prohibited on US passenger-carrying aircraft. Lithium metal battery fires require a class D (flammable metal) fire extinguisher.
They're vague about the safety issue. "We're going to make the anode ultra-thin" is a concern. There are safer battery technologies, such as lithium iron phosphate. That won't run away thermally, and passes the "nail test", where a nail is driven through the battery. Less capacity than regular lithium ion, which is why it's not widely used, although you can buy such batteries commercially from A123. "Boosted" skateboards use them, because they don't blow up.
Solid Energy Systems, submit your cell for UL testing. Otherwise, lithium metal is, literally, not going fly.
